User Acceptance Tests Form the Top of the Test Pyramid

User acceptance tests (UAT) are a type of software test carried out by the end users of an application. The aim is to ensure that the software fulfils certain requirements and expectations. The aim is to test the technical requirements as well as the user-friendliness and functionality.

How Do User Acceptance Tests Work?

User acceptance tests are an important step in the development process of an application and take place in the final phase before the software is deployed. The following factors are usually checked in this test phase:

  • Functional requirements: Here, users check whether the software enables the desired functions and processes and fulfils the original requirements for the software.
  • User-friendliness: Users evaluate the usability and design of the application. “Is the user interface intuitive and easy to understand?” is the key question.
  • Workflow requirements: Users test whether the software maps important workflows and fulfils the specific requirements.
  • Migration and compatibility during updates: When updates or changes are made, a check is carried out to ensure that existing data and functions continue to function correctly and that migrations can be carried out smoothly.
  • Scenarios: Different application scenarios are run through to ensure correct functioning.


What Is a Test Pyramid?

A test pyramid is a concept from software development that depicts the hierarchy of different test types in a hierarchical structure. The idea is to establish an efficient strategy for testing software.

A test pyramid typically consists of the following levels:

Unit tests form the basis of the test pyramid and test individual units of an application in isolation from each other.

The middle layer of the test pyramid is occupied by the integration tests. They check the cooperation of components and interfaces to ensure proper interaction. Any problems are thus detected promptly.

System tests represent a further level and test either parts of the system or the system as a whole. The focus here is primarily on the correct integration of all components. They also test whether functional and non-functional requirements are met.

With the User Acceptance Tests, end users ensure that the system not only meets their requirements, but also offers added value.

The test pyramid is based on two dimensions. The horizontal axis represents the number of test cases that are performed for an application. The vertical axis represents the complexity of the tests.

The vertical axis can be interpreted as the complexity of the test cases, the speed of execution or the type of validation.

Why Are UATs at the Top of the Test Pyramid?

User acceptance testing is crucial to identify potential problems or shortcomings – and therefore serves as the final step before the application is deployed. User feedback and evaluation are essential because they ensure that the application is suitable for the intended target group.

User acceptance tests focus on the customer perspective. When developing an application, the main goal is to maximise customer value. This should ensure that the end product meets the needs and requirements of users in practice.

The different perspectives also contribute to a differentiated picture of the software, as the tests provide important feedback on other use cases. Certain aspects may have appeared acceptable to developers in earlier test phases, whereas they are unacceptable to users.


Placing user acceptance tests at the top of the test pyramid emphasises the importance of the individual customer. They represent the highest degree of customer orientation. UATs are crucial for the commercial success of software, as they ensure that the desired customer benefit is fulfilled and added value is offered.

Software Testing Before Launch: 5 Tips for a Smooth Launch Experience

All software must be tested before launch. If this part is omitted, a whole host of bugs and security gaps in the code remain undiscovered.

We at have already been involved in many projects and can confirm this: Problems can always be found before the release. And the more complex your product is, the more bugs there will be (best example: Windows). That’s why testing is a central part of software development. And this part has to be done right.

Here we share with you 5 tips on how to ensure a smooth launch experience with tests.

Tip 1: Test Right from the Start

This tip comes first because it is the most important.

If your software is already “finished” and you want to start testing it quickly before the launch, you have already made a critical mistake. Because testing software is not something that should only be done shortly before the launch. It has to be done right from the start. And on a regular basis.

Software products work in much the same way as buildings: there is a structure. Each building block builds on another. And if the foundation is not built properly, everything that builds on it has to be demolished.

If you find out 2 weeks before the rollout that the entire structure of your code needs to be reorganised, there is always the same consequence: a headache.

Employees have to work overtime, your superiors are stressed, clients are dissatisfied and the company builds up a bad reputation. Early testing prevents this.

Integrate Testing into the Product Roadmap

If you want to plan your testing strategically right from the start, you need to integrate it into the product roadmap. This allows you to determine at which points in the development process which tests are to be carried out.

A major advantage of this approach is also better time planning. One of the most common excuses for not testing is “too little time”. And it’s true that software development is stressful. But if you plan everything from the beginning, you can set realistic deadlines and schedule time for testing.

Also important: The coders should be involved in the creation of the product roadmap. This is because they are good at estimating how long certain tasks and processes will take.

And if you have particularly little time for testing, you can try automated testing as a service (TaaS).

Tip 2: Carry Out the 4 Most Important Tests

These 4 tests must never be omitted before the rollout:

  • Unit tests
  • Integration tests
  • End-to-End tests
  • Acceptance tests

They test different areas and complement each other. Once your software has passed these tests, you can have much more confidence and trust in the product. But what are these tests all about?

Unit Tests – Check Isolated Code Sections

Unit tests require you to scrutinise and check small sections of code (units). This type of test must be carried out particularly early on so that errors in one unit do not affect other units.

Integration Tests – Checking Harmony between Units

With complex software, different units have to communicate with each other (e.g. front-end and back-end modules).

You use integration tests to check whether these units are in harmony with each other. Because if the interfaces have errors, this usually hinders the flow of data in the system.

End-to-end Tests – Testing the Entire System

End-to-end tests are larger tests that check the behaviour of the entire system from start to finish.

As already mentioned, software consists of various components. And in end-to-end tests, it is not individual parts of the software that are tested, but the entire system. In such tests, the software has to prove itself in real-life scenarios.

Acceptance Tests – Checking the Client’s Needs

The acceptance test always comes at the end. It is not carried out by you, but by the customer or an end user. If the tester has no problems and can navigate the application without help, the test is considered passed.

Tip 3: Put your Software to the Test!

When a carpenter has finished his work, he hammers hard on his table. This is done to test the stability of the table. When testing software development, something similar is done to the finished application. It is called fuzzing.

When fuzzing, the system receives unexpected and invalid input data. An active attempt is made to overload the system. This has the following advantages:

Security Gaps Are Uncovered

If you actively overload your software with fuzzing, you can recognise vulnerabilities based on the system’s reactions. This is important because such vulnerabilities are exploited by attackers.

Resilience Is Tested

If the software crashes during fuzzing, this means that the code does not provide enough stability. You can use such stress tests to find out whether the software is robust enough for the launch.

A crash is often caused by the code being too long and not being kept simple.

Regression Can Be Detected

Regression means that old errors that have already been corrected reappear. Unfortunately, regression often goes unnoticed. But if you carry out fuzzing regularly, you can detect such errors.

Tip 4: Use Flaky Tests

Most developers don’t like flaky tests. Because they are confusing. A flaky test leads to different results under identical circumstances. This is why these tests are usually deleted.

But you can actually use flaky tests to your advantage. If you find out what causes the test to be “flaky”, you can get to the bottom of problems that other tests don’t reveal.

Tip 5: Write Test Reports that Everyone Understands

Automated test reports have become very popular. They save a lot of work. But there is one problem: they are not always reader-friendly and often require a lot of knowledge. There are always participants and decision-makers in the project who do not have a deep technical understanding. In order to make informed decisions, they need to be able to understand the test reports.

For example, there could be a bug that cannot be fixed before the launch. In such cases, the decision-makers need to understand the bug. They have to decide whether the launch has to be postponed or whether the software can be released despite the bug. And this is only possible if the test report is clear and comprehensible. Even if the reader does not have a great deal of technical understanding.

The good news: There are also automated test reports that are easy to understand. At, we produce image-based test reports. They are easily understood by everyone involved. Contact us if you want to know more about this.

How Test Automa­tion Puts the Efficiency of Your Project in the Fast Lane

Imagine you are a passionate developer working on an exciting software project. The deadline is approaching and you feel the pressure to deliver a bug-free application that runs smoothly and delights users. But as you write the lines of code and perfect the functionalities, the fear of hidden bugs inevitably creeps in – those little imperfections that only become noticeable when the application gets into the hands of users.

Wouldn’t it be fantastic if all these worries could just disappear? Imagine if you could rely on your tests to be thorough, comprehensive and accurate – without the hassle and uncertainty of manual testing.

The solution to these concerns lies in the world of test automation.

In this article, we’ll dive into the exciting world of test automation together and explore how it can put your project’s efficiency on the fast track. We’ll see how tedious manual testing can become a thing of the past and how you can achieve better test coverage with ease. But that’s not all – we’ll also learn about an innovative solution that not only automates your testing, but also introduces the concept of Testing-as-a-Service (TaaS) to make your development journey even more seamless.

Join us on this journey as we overcome the obstacles of manual testing, maximising the efficiency of your development while ensuring that your application meets the highest quality standards. Let’s dive into the world of test automation and discover how you can save time, resources and nerves – without compromising on quality.

The Challenges of Manual Testing

Ah, the human factor – it can be a blessing, but also a curse. Sloppy mistakes, fatigue and carelessness can affect your tests. Manual testing can be a significant challenge in software development for a number of reasons:

  • Time required: Manual tests require a lot of time and resources as they have to be carried out manually by testers or developers. This can be particularly time-consuming for complex or extensive applications.
  • Repeatability: Repeatability is a problem with manual tests. As people are involved, tests cannot always be carried out in exactly the same way, which can lead to inconsistencies in the test results.
  • Human error: Manual tests are prone to human error such as sloppiness, fatigue or lack of attention. These errors can lead to errors in the application being overlooked or incorrect results being reported.
  • Limited test coverage: Due to time and resource constraints, manual tests cannot cover all possible scenarios and combinations that may occur in a complex application. This can lead to critical errors remaining undetected.
  • Scalability: Manual tests are difficult to scale. As the application grows or new features are added, more tests are needed, further increasing the time and resources required.
  • Costs: Manual testing can be costly as it requires teams of testers to continuously perform and monitor tests. This can put a strain on development project budgets.
  • Slow feedback cycle: Manual testing delays the feedback cycle for developers as they have to wait for test results from testers. This can hinder development and lead to longer iteration times.
  • Lack of reproducibility: With manual tests, it is often difficult to reproduce and isolate errors, especially if they occur intermittently. This makes troubleshooting and verification more difficult.
  • Complexity: Manual testing can be difficult in complex applications as they may require testing of different platforms, devices or environments. This can complicate the testing strategy.

As you can see, manual tests pose a major challenge, especially in terms of efficiency, consistency, test coverage and quality assurance. But don’t worry! Test automation takes this human factor out of the equation. No more mistakes due to daily form or tired eyes. The machine takes over.

Why Test Automation?

You certainly know the importance of testing for the quality of your software. But imagine if all those tedious tests could be automated! This is where test automation comes into play. It’s not just about saving time, but also about improving test coverage. Because we all know that manual tests can only scale up to a certain point.

Test automation brings with it a wealth of benefits that can significantly increase the efficiency and quality of your software development. Here are some of the most important advantages:

1. Faster Test Execution

Manual tests can be time-consuming, especially if they have to be repeated regularly. Test automation makes it possible to carry out tests in less time and at a higher speed, which speeds up the development process.

2. Higher Test Coverage

Manual testing can leave gaps in test coverage as it is difficult to cover all possible scenarios. With automated testing, you can run a wider range of test cases to ensure that different aspects of your application are thoroughly tested.

3. Consistency and Repeatability

Automated tests deliver consistent results, regardless of factors such as daily form or fatigue. This ensures the repeatability of the tests, which is important for tracking changes in the code over time.

4. Early Detection of Errors:

Automated tests can be used in the early stages of development, leading to the early detection of errors. This makes it possible to identify and rectify problems at an early stage, which ultimately reduces the cost of later corrections.

5. Better Utilisation of Resources

Automated tests can be executed in parallel, which maximises the utilisation of available resources. As a result, tests can be completed more quickly without overloading the resources of developers and testers.

6. Reduction of the Human Factor

Manual testing is prone to errors due to sloppiness, fatigue or human error. Automation eliminates this human factor and helps to improve the accuracy of test results.

7. Cost Efficiency

Although the initial outlay for setting up test automation must be invested, it leads to cost savings in the long term. Automated tests reduce the time and resources required for repeated manual tests.

8. Support of Continuous Integration and Continuous Deployment (CI/CD)

Automated tests are a crucial component of CI/CD pipelines. They enable code changes to be checked quickly and reliably and transferred to the production environment.

9. Scalability

With automated tests, you can easily scale test coverage by adding new test cases or updating existing ones. This is particularly useful as the application grows or new features are added.

Overall, test automation offers a variety of benefits that can improve the quality of your software, speed up the development process and utilise your resources more efficiently. It is an investment that pays off in the long term and helps to bring high-quality software to market faster and more reliably.

How does Test Automation Work?

Test automation refers to the process of using automated tools and scripts to perform software tests instead of having them performed manually by testers. These tools can use different techniques and approaches to automate tests. Here is a basic idea of how test automation works:

1. test script creation: First, test scripts or test cases are created that describe how the application is to be tested. These scripts are usually written in a specific scripting language or an automated test framework.

2. test tool selection: Automated test tools are selected that can automate the desired test scenarios. These tools can range from general test automation platforms to specialised tools for specific types of tests.

3. Set up the test environment: The test environment, which contains the application to be tested and all necessary dependencies, is prepared. Depending on the type of application, this can include various aspects such as software versions, databases, operating systems and hardware configurations.

4. Automation of the tests: The test scripts created are executed in the selected test automation tools. These tools can simulate the application, execute user input, compare expected results and detect errors.

5. Test execution: The test automation tools execute the created test scripts by controlling the application, executing actions and checking expected results. They can manipulate GUI elements, call APIs, query databases and more.

6. Test reporting: On completion of the tests, the automation tools generate reports on the test results. These reports contain information about which tests were successful, which failed and any errors that occurred.

7. error detection and correction: If automated tests fail, they indicate potential errors or problems in the application. Developers can use the reports to determine the exact cause of the error and fix it.

8. Integration into CI/CD pipelines: Automated tests can be integrated into Continuous Integration and Continuous Deployment (CI/CD) pipelines to enable seamless integration and deployment of code changes.

9. Scaling and maintenance: The test scripts can be updated and expanded as required to cover new functionalities or changed requirements. This enables continuous maintenance of the test automation.

Overall, test automation aims to reduce the manual effort involved in performing tests, increase test coverage, improve the accuracy of results and provide developers with quick feedback on the quality of their code. It also facilitates the execution of tests in different environments and ensures that repeated tests deliver consistent results. The Efficiency Revolution

The Test Pyramid: Components of an Effective Test Strategy

In addition to the planning and implementation of programming work, the development of new software also includes successful integration. Comprehensive testing is therefore a key factor in ensuring the introduction of a new system.

These tests uncover problems and errors that need to be rectified before delivery to the customer. The various tests build on each other. In this article, we introduce you to the so-called test pyramid and its meaning.

Comprehensive Tests – From the Base to the Top

Comprehensive testing of newly developed software is as important as the programming itself. Comprehensive testing of the system is therefore central and important before the product is launched at the customer. It serves as quality assurance. Testing makes it possible to recognise and rectify problems before the software reaches the end user. Testing should therefore take place from as many perspectives as possible. This is the only way to ensure that the customer can use the finished end product without any problems.

There are basically four different test procedures that should be carried out before finalising new software: Unit test, integration test, system test and acceptance test. The four different tests systematically build on each other and should therefore all be carried out.

In this context, we also speak of the test pyramid. The unit or component test forms the basis. The integration test builds on this at the second level, followed by the system test. The top of the pyramid is the acceptance test. Software that has made it this far should generally only have minor errors. The acceptance test is the last step before the customer, so to speak.

In the following, we will take a closer look at the test pyramid and explain what is tested on the four levels and why these tests are so important.

Basics First – The Unit Test

The unit test has different names, whether unit, component or module test, the purpose remains the same. In the test process, the unit test is used to test the smallest units of software code. These units are considered independently of each other. Only if the smallest parts are functional can the entire software system run without errors.

Unit tests form the basis of the test pyramid, which is obviously due to the fact that this is about the many individual codes that together form the software. The aim of analysing and checking is to find errors in these smallest units at an early stage. The testing process can be divided into four phases.

  • Planning: In order to carry out a test procedure efficiently, the process should be planned in advance. This includes, among other things, securing resources and personnel.
  • Test cases: The development and preparation of use cases follows on from planning.
  • Scripting: Creation of the scripts needed to perform the unit test.
  • Unittest: The testing of the individual units naturally comes at the end of the process. The results lead to the optimisation of the software units.

There are different methods for implementing a unit test. Both manual and automated options are available. Manual tests have a greater level of detail, as each individual step is documented. Automated procedures only provide information on the failed units.

Although a unit test cannot usually uncover all errors in the smallest units, this procedure provides early indications of problems. Costs are reduced by optimising the code units identified as faulty. The basis for further tests is also optimally prepared.

Step Two – The Integration Test

In the second step, software testing concentrates on the interaction of several units that were previously checked in the unit test. In the course of a complete test process, the focus widens. After the detailed testing of the individual units, the field of vision is now larger.

Integration tests look at the cooperation between the units, i.e. whether a unit refers to another unit, uses its interface and whether this works smoothly. It is precisely at these interfaces that errors can occur, which a unit test cannot identify due to its focus on the smallest part.

The result of the integration test shows which interfaces between two or more units do not fit together properly. Sources of error can thus be eliminated in a targeted manner.

Step Three – The System Test

The step-by-step check of the interfaces in the integration test is followed by the system test, which again has an expanded focus. As the name suggests, the entire software system is now put to the test. All other systems are now added and analysed as an overall construct. The aim is to clarify whether the software does exactly what it is supposed to do and whether unexpected errors or problems occur when the individual components work together.

Compared to a unit test, system tests require more time, resources and personnel. At this point, the effort required correlates with the complexity of the task. The test combinations are almost infinite. It is therefore important to utilise the resources efficiently. A customised test environment is therefore the be-all and end-all before carrying out the system test.

Once the software has successfully passed the system test and it has been ensured that all requirements have been met, the test process can be finalised.

At the Top – The Acceptance Test

In some cases, the system test is also the final stage of the test pyramid. However, the value of an acceptance test should not be underestimated. Once a software has gone through all the previous steps and the tests and corresponding adjustments have been made, it is worth carrying out a final test to scrutinise the overall construct once again.

The acceptance test is also known as acceptance testing. It is the really final step before the software is delivered to the customer.

This last test is a so-called black box test. The parameters of the test must therefore be defined in advance. The tester therefore determines all the characteristic values that are used to check the input and output data. Depending on who carries out the test, the acceptance test belongs to a different category. There are three different categories.

  • Customer Acceptance Testing: The tester is an external supplier
  • Factory Acceptance Testing: The tester examines the components
  • User Acceptance Testing: The tester is the user

User Acceptance Testing (UAT)

Whether referred to as beta, application or end-user testing, the most important sub-category of acceptance testing is user acceptance testing. Why is it so important? Quite simply, in this process the customer himself checks the software for its handling and usability. Feedback from the customer is some of the most helpful feedback a developer can get.

Ziel einer Software-Programmierung ist es, dem Kunden genau das Produkt zu erstellen, das er sich wünscht. Im UAT testet der Kunde nun die Software auf Herz und Nieren und schau, ob alles so funktioniert, wie es soll. Es steht damit die Benutzerfreundlichkeit und die Akzeptanz seitens der Anwender im Vordergrund.

For programming, the user review provides insight into topics such as Is the software intuitive to use? What problems occur during use? Does the software crash and in which situations does this happen?

If problems and errors occur, the manufacturer has the opportunity to make further adjustments and identify and eliminate the sources of error. In serious cases, the result is more labour-intensive, namely when important applications have been forgotten during programming or the user expresses further wishes when trying out the system.

Support with Testing

The various tests in the test pyramid are essential for bringing a successful product to market. While unit tests are carried out relatively quickly, the complexity and time required increase as the focus of the other tests increases. System tests and, above all, acceptance tests are therefore very time-consuming. In addition, system and acceptance tests are generally not automated and require manpower to carry them out.

In order to ensure the quality of the software, it is therefore advisable to consider support for the time-consuming tests. can help with user acceptance testing. One example clearly shows how the support provided by the experts works:

A customer had been struggling for some time with problems that occurred during his product demos. He was unable to remedy the problem himself and the source of the error could not be found. As the malfunctions were already leaving a bad impression on potential and existing customers, quick help was needed. provided the customer with the test environment, which was used to find the source of the error on the basis of comprehensive, automated tests. What did the customer do with the help of the test environment? It used the test tools to run through different scenarios and simulate the software in these examples. Since then, it has used the test environment for all product demos, as this allows it to ensure quality.

This shows that with, developers and project managers have a strong and competent partner at their side.

Climbing the Pyramid – Taking the Fear Out of IT Tests

Software errors can have a negative impact on the acceptance of the product. System crashes or malfunctions frustrate the user and dampen confidence in the application or the manufacturer. Even if they consume resources and time, extensive tests are therefore an important element in the development process. The test pyramid is a clear way of visualising the structure of the test process.

According to the pyramid, the test procedure should be well planned and prepared in advance. Good preparation ensures that there are no further undesirable delays during the test procedure. Test environments such as those from make test implementation even easier.

If you are looking for a solution to simplify the introduction of new software and support it with high-quality product demos, you should give a try. Rely on thorough testing and convince your customers.

Best Practices for the Successful Transition from Manual Testing to Automation

The transition from manual testing to automation is crucial in today’s fast-paced software development world. By automating testing processes, organisations can increase efficiency, improve quality and reduce time-to-market. However, there are some challenges to overcome, including careful planning, strategic approaches and collaboration between all team members.

A successful transition requires recognising best practices and implementing appropriate steps. For example, clear objectives should be defined, suitable tools selected and test scripts developed. Regularly reviewing and updating automated tests and training team members are also important aspects of a successful transition. With a well-thought-out approach, a company can ensure that it realises all the benefits of automation and continuously improves its software quality.

1. Thorough Analysis and Planning

The first and most important step for a successful transition to test automation is thorough analysis and planning. This involves understanding the goals, requirements and scope of the automation project. By identifying the appropriate test cases, resources can be utilised effectively. The prioritisation of test cases is based on their importance and the expected ROI (return on investment). Examples of suitable test cases could be regression tests, where a large amount of repetitive tasks can be automated. Performance tests or tests in complex environments can also be automated well. Careful planning lays the foundation for efficient and successful test automation.

Create a detailed time and resource plan for the automation project. Firstly, you should estimate the time required for the actual automation, taking into account specific tasks such as identifying processes that can be automated, developing scripts or testing the automation. Furthermore, it is essential to plan enough time for training team members to ensure that they have the necessary skills to carry out the automation successfully.

The familiarisation with new tools and technologies should also be considered, as these may require additional training. It may make sense to bring in external expertise or offer training to ensure that the team has the necessary knowledge.

2. Selection of the Right Tools

Choosing the right automation tools is crucial to the success of the project. There are a variety of test automation tools on the market, from open source options such as

  • Selenium
  • Appium
  • JUnit

to commercial solutions such as

  • Applitools
  • TestCafe
  • UFT
  • TestComplete
  • UIPath

Choose the tools that best suit the requirements and technologies of your project.

When selecting development and testing tools, copywriters should consider various aspects. Firstly, scalability is important – the selected tool should be able to keep pace with growing requirements. In addition, it should offer broad support for different platforms and technologies to ensure that a wide range of projects can be covered. The maintainability of the tool also plays a role, as it requires regular updates and bug fixes. An active community can help to clarify questions and solve problems. Finally, integration with other development tools is important to ensure a seamless workflow.

3. Gradual Introduction and Pilot Projects

A step-by-step approach is often recommended to make the transition from manual testing to automation a success. Start with a pilot project to familiarise the team with the new tools and methods and gain experience. Select test cases that are relatively easy to automate and offer a high benefit for the project.

After the pilot project has been completed and the results analysed, it is advisable to obtain feedback from the team members. This feedback can provide valuable insights and help to adapt the approach if necessary. If the pilot project is successful, it opens up the possibility of extending automation to other test cases and projects. This allows for more efficient testing and gives the team more time for other important tasks. Examples of possible extensions could be the integration of additional test tools or the automation of other project management processes.

4. Test Data Management

A critical aspect of test automation is test data management. Automated test cases require reliable and consistent test data in order to function correctly. Ensure that test data is managed in a clean and predictable environment.

Using mock data is an effective way to simulate databases and external dependencies in tests. By separating test data from production data, privacy regulations can be adhered to and potential data leaks can be avoided. Let’s imagine a developer is working on an e-commerce website and wants to test different scenarios, such as adding products to the shopping basket or completing an order.

Instead of using real customer data or credit card information, mock data can be generated, such as random names, addresses or credit card numbers. This mock data is realistic enough to perform realistic tests, but anonymised enough to protect user privacy. In addition, the use of mock data allows for greater flexibility in creating specific test cases and scenarios without compromising the actual production environment.

5. Code Quality and Versioning

Automated tests are essentially code, so code quality is critical. Follow best practices for software development, such as modular and well-structured code, clear commenting and consistency in the naming of variables and methods.

Effective version control is crucial for managing the code of automated tests. It enables the team to track changes and undo them if necessary. This not only minimises the risk of errors, but also improves collaboration. An example of a popular version control software is Git, which allows developers to create branches and work on different features or fixes in parallel.

In addition, Git provides features such as merging and rebasing to merge changes into the main code and resolve conflicts. With well-managed version control, the test team can go through faster feedback loops and ensure that all changes are properly documented.

6. Continuous Integration and Continuous Testing

Integrate test automation seamlessly into the CI/CD (Continuous Integration/Continuous Deployment) process. Automate the execution of tests when new code changes are submitted. This enables potential problems to be recognised and rectified at an early stage and the quality of the code to be improved.

By automating the deployment and execution of tests in different environments, a copywriter is able to ensure that an application works both consistently and reliably. This makes it possible to identify potential problems or incompatibilities at an early stage and take appropriate countermeasures. For example, it is possible to test whether a website is displayed correctly on different browsers or whether mobile apps run smoothly on different operating systems.

In addition, different network conditions can also be simulated to ensure that the application functions optimally under different connection qualities. Overall, the automation of tests in different environments helps to significantly improve the quality and performance of an application.

7. Continuous Improvement and Training

Test automation is an ongoing process that requires continuous improvement. Gather feedback from team members and stakeholders to identify potential weaknesses and bottlenecks.

Continuous investment in training and development of the team is vital to ensure they always have the latest skills and technology. This enables team members to keep up with constantly evolving requirements and maximise their efficiency. For example, test automation training could be provided to ensure that the team has the necessary knowledge and skills to automate tests effectively.

It is also important to keep up to date with developments in the field of test automation and adapt the strategy and tools accordingly. New tools and techniques such as Continuous Integration or Behaviour Driven Development can help to further optimise the automation process. Overall, a well-trained team helps to ensure that tests can be carried out more efficiently, thereby improving the quality of the software.


The transition from manual testing to automation brings numerous advantages for companies. By using automated tests, they can optimise their software development and shorten the time-to-market. This enables faster delivery of updates and new features to customers. By thoroughly analysing the requirements and scope of testing, companies can ensure that they select the right tools for their test automation. A step-by-step approach is advisable to minimise the risk of errors and ensure a smooth transition. It is also important to integrate test automation into the already established CI/CD process to enable continuous integration and deployment. Examples of suitable tools are Selenium, Appium or JUnit, depending on the specific requirements of the project. The use of frameworks such as Behaviour Driven Development (BDD) can also help to create clear and understandable test scenarios.

Continuous improvement and training of the team is crucial to keep up with the latest technologies and best practices and to ensure efficient test automation. By regularly training the team, they can expand their knowledge of tools such as Selenium or Appium and develop new automation strategies. In addition, best practices such as setting up a continuous integration system or implementing code reviews can help improve the quality of the software. Costs can be reduced by recognising and correcting errors early on in the development process. This not only leads to higher customer satisfaction, as high-quality products are delivered, but also to a motivated team that is constantly developing and growing.

If you do not yet have the necessary expertise in-house to make the switch from manual to automated tests, you can also opt for a Testing-as-a-Service solution. The provider takes over the testing for you. You can find more information about this service at

The Relationship between Conventional User Acceptance Testing (UAT) and Customer Satisfaction

Is the customer satisfied? This question is answered with the UAT – the last important step in software development. It cannot be automated. And skipping it is not a good idea.

Because this test has a great influence on the customer’s satisfaction. That’s why you have to pay special attention to how it is carried out. Because it is about much more than the functionality of the application.

If you want to have customers who praise your business and recommend it to others, read this article to the end. Here we explain how the UAT influences customer satisfaction and how you can use this to your advantage.

The Basics: What Are UATs All About?

Applications are usually tested by developers. This is because there are many types of tests that require a lot of expertise. But with UATs, an end user tests the application. Without any prior knowledge.

For example, if you have developed a customer relationship management software, it has to be tested by a salesperson at the UAT. Or if you have developed a video game, it should be tested by a gamer.

At the end of the test you must be able to answer the following: Does the end user find his way around? Or is he confused and unable to navigate the application without help? The test scenario must always be as realistic as possible.

Step by Step: This Is How a UAT Must Proceed

A successful UAT is planned and has a clear process.

Step 1: Set the test objectives

At the beginning, you need to define what a successful test would look like. You also need to define the circumstances under which the test is considered a failure. It would be best if you define this together with the client. That way you have common expectations for the test.

Step 2: Planning

For a UAT, you have to prepare a lot of things. For example, you need to find end-users and, if necessary, sign a non-disclosure agreement with them. Also decide whether the test will take place via Zoom or in an office.

Also be careful when scheduling time. Unexpected errors can occur that prolong the whole process. (If you have been to UATs before, you probably know that the demonstration effect also exists in computer applications).

Step 3: Implementation

There must be a lot of concentration during the performance. Avoid distractions as much as possible. And most importantly, record everything that happens during testing, otherwise you will lose all the feedback.

Step 4: Reporting

Prepare a report by evaluating the results of the UAT. Then you have to determine the next steps in consultation with the client.

What Influences Customer Satisfaction

Before we talk about the relationship between UATs and customer satisfaction, it is important to clearly define how customer satisfaction is created in the first place.

IT service providers often have a simple answer to this question: “A good end product makes the customer happy” is often said. But that is not the complete answer. Because you are not just offering the customer an end product, but a process.

Was this process painful and exhausting? Then the client will be less satisfied with your service, despite a good end product.

In addition, applications must be produced in collaboration with the customer. For this collaboration to work well, pay attention to the following:

  • Communication
    Ask the client many questions. This shows that you want to understand them. Customers always want to feel that their needs are being addressed. Also remember to give regular updates. If there is a long period of radio silence, your client will feel neglected.
  • Transparency
    Something is not going as planned? Don’t try to cover it up. Instead, talk openly about challenges and share how you plan to solve your problems. This builds trust. But if deadlines have to be pushed back unexpectedly, customers feel disappointed.
  • Adaptability
    Not all clients know what they really want. And a client’s wishes can change in the middle of a project. You have to react to this professionally and be as adaptable as possible. However, there are also limits. Not all changes of direction are realistic in software development. But in such cases, you can’t just say “no”, you have to offer the client several options.

Why UATs Are Crucial for Customer Satisfaction

Einer der stärksten Faktoren, der Kundenzufriedenheit beeinflusst, ist der Ablauf des UATs. Das sind die Gründe:

  • Customers actively participate in the development process
    In UAT, customers are highly involved because they voice their opinions and concerns. Because of this involvement, a stronger bond with the product is created. Those who participate in cooking appreciate the food more.
  • Perception of quality increases
    With a smooth UAT, the customer’s confidence in the product increases. There is a sense of security before the launch. However, there can also be an opposite effect if the test does not go well. But usually there are no perfect UATs where no suggestions for improvement can be collected. In fact, it has a better effect on the client’s satisfaction if they find suggestions for improvement themselves. Because that way you can implement their ideas. And in the end, they have a product that they know works exactly as they want it to.

How to Conduct UATs for Maximum Customer Satisfaction

Now you know how a UAT influences your customers’ satisfaction. But there are other aspects you need to consider to ensure that the UAT maximises your customers’ satisfaction:

Ask Questions in the Right Way

During the UAT, you have to ask the client many questions. And these questions must be thoroughly prepared beforehand. But the way you ask these questions has a big impact on the client’s perception.

Wrong: In your opinion, has this feature been implemented well?

Right: You expressed at the beginning that [need] is important to you. That’s why we implemented [feature]. Does this meet your expectations?

This shows that your product is not a general solution, but a customised application. Therefore, do not use generic questions. Prepare an extremely individualised questionnaire!

Keep the Process Simple

UATs must not be too long. Because if the testers lose concentration, they can make human errors.

The process must also be simple. This way, all participants can follow attentively without anyone getting lost in thought.

Get the Customer Talking

A big problem with UATs is shy clients. They prefer to keep thoughts to themselves and are not comfortable voicing criticism.

You have to counteract this. Create a relaxed atmosphere and let the client know that criticism will not hurt their feelings. It also helps to provide multiple feedback channels. For example, some prefer to provide certain concerns in writing afterwards.

And now?

With the help of the UATs, the application was improved and optimised and finally taken live. The customers are satisfied and everyone is happy. End of story.

No, because now it’s about keeping the customer satisfied too. This is where the automated UATs come into play. They keep checking that the customer’s wishes continue to be served and that important suggestions are not suddenly ignored.

The importance of unit tests for reliable software development and how they can be usefully supplemented

Are you always looking for ways to make your software development more robust and reliable? Then stay tuned, because today we’re diving into the fascinating world of unit tests and showing you why they’re at the heart of solid software development.

Why Are Unit Tests so Important?

Imagine you are building a house. Before you paint the walls and lay the carpets, you want to make sure the foundation is solid, right? That’s what unit tests are in the software world – they are the foundation on which your application stands. These tests take small pieces of your code and check that they work as they should. You don’t want one tiny bug to bring down the whole building, do you?

Unit tests are a basic method of checking the functionality of individual components or modules of an application. They work by testing specific parts of the programme code in isolation, usually individual functions or methods. In this isolated environment, input data is provided and the expected output results are predefined. When the unit test is executed, it compares the actual output results with the expected results. If they match, the test is considered to pass, otherwise an error is reported. Unit tests are usually automated, which means they can be run quickly and repeatedly to ensure that changes in the code do not have undesirable side effects on existing functionality. This thorough testing process at the smallest level helps to detect errors at an early stage and improve the overall quality of the software.

Complement Unit Tests with End-to-End Testing – A Fantastic Idea

Sure, unit tests are fantastic, but look a little further ahead. At the end of the testing process you will find the end-to-end tests. This is where your software is put through its paces by real users. Sounds exciting, doesn’t it?

Supplementing unit tests with end-to-end tests is a best practice in software development that offers several benefits. Here are some reasons why it is a good idea to use both types of tests in your development strategy:

1. Holistic testing: End-to-end testing simulates the actual running of an application by bringing together different components and modules. This makes it possible to check the interactions between the different parts of the application and ensure that they work smoothly when working together.

2. Realistic scenarios: End-to-end tests can simulate real user scenarios where multiple steps are performed in the application. This ensures that the application is tested in an environment that is as close as possible to real-world usage and helps uncover potential problems that may not be detected in isolated unit tests.

End-to-end tests cover integrations between different modules and services. This is especially important if your application consists of multiple services or APIs, as they ensure that all interfaces work properly and data is transferred correctly.

4. overall view error detection: While unit tests tend to focus on specific parts of the code, end-to-end tests identify errors caused by the interaction of different components. An error can show up at the interfaces between components, disrupt the data flow or cause unexpected behaviour.

5. Confidence in overall quality: The combination of unit tests and end-to-end tests provides a higher level of confidence in the quality of the application. While unit tests ensure the correctness of small sections of code, end-to-end tests provide a more comprehensive view of the entire application and help identify potential problems on a broader level. Your Companion to End-to-End Reliability

So if you want to look beyond unit tests, is your new best friend. This platform helps you not only test the small building blocks, but also ensure that your entire software runs like well-oiled clockwork. gives you the power to test in a cloud of ease and efficiency. No tedious installation and configuration – just log in and test, ensuring your software meets the highest standards.

Conclusion: Your Software, Strong as a Bear!

In the end, your decisions influence how robust and reliable your software will be. Unit testing is the first step, but don’t forget to go a step further afterwards. And for the ultimate polish, we recommend you take a look at and find out how we can help you with your testing.

Acceptance Testing – How to Make Sure Your App Meets Users’ Expectations

Acceptance testing, also known as User Acceptance Testing (UAT), is an essential step in the software development process. Their main goal is to ensure that an application meets users’ expectations and satisfies their needs. In this post, we take a closer look at how acceptance testing works.

You can find out more in this article:

  • what acceptance tests are
  • how acceptance tests work
  • what types of acceptance tests there are

Why Acceptance Tests Are Relevant

By testing an application from the user’s perspective, potential defects can be identified before the software goes into regular operation. UAT involves running through different scenarios to ensure that all functions run properly. Examples of UAT could be:

  • filling in a form on a website
  • the testing of search functions
  • trying out support materials such as help pages.
  • Checking the correct display of content on different screen sizes

These tests enable developers and customers alike to optimise the product before launch and ensure that it meets the desired requirements. Acceptance testing is an essential part of application quality assurance. A positive test result ensures that the likelihood of the application actually being used after its release increases.

How Acceptance Tests Work

Before the acceptance test, different test criteria are defined that the application must fulfil. These test criteria can, for example, relate to usability and specific functions. Acceptance testing actively involves real users in the evaluation process of an application before it is released. This procedure provides an invaluable opportunity to understand the needs and expectations of future users.

Feedback and suggestions for improvement can identify and address weaknesses to ultimately ensure an optimal user experience. The UAT can take different forms, for example, internal acceptance tests with company employees or external tests with a representative target group.

Volunteers or paid testers are invited to put the application through its paces. The feedback from the testers is recorded in detail and then forwarded to the developers or other responsible persons. This enables them to make appropriate changes before the application is published.

Types of Acceptance Tests

We know different types of user acceptance tests:

  • Beta Test
    When conducting a beta test, the main focus is on determining whether an application meets general expectations. This test is ideally conducted by end users who belong to the actual target group.
  • Operative acceptance test.
    Operational acceptance tests ensure that the workflow of a software really works.
  • Black Box Test
    In black box testing, the testers check the functions of a software, but without having any knowledge of the underlying code.
  • Performance Acceptance Test.
    A performance acceptance test is a useful tool for testing the functionality of an application under different conditions of use. For example, it can be used to test whether an application works reliably even with a high level of simultaneous use by a large number of testers.
  • User Acceptance Test.
    A user acceptance test is an effective method to evaluate the user-friendliness of an application. Testers are given various tasks to find out how intuitive and straightforward the operation of the application is. For example, they might be asked to find certain functions or perform actions.

When conducting acceptance tests, different types can be used, varying according to the requirements and circumstances. The selection of the appropriate test type depends on factors such as the test environment and requires a detailed analysis of the requirements.

 Conclusion: What Are Acceptance Tests?

Acceptance tests are the last step before an application is published. They should paint as realistic a picture as possible of how high the acceptance of the application is among future users. That is why real test persons are used here. Their feedback forms the basis for any changes before publication. Because acceptance tests are important. Beta tests and user acceptance tests are carried out manually because experience and intuition cannot yet be automated.

Operational acceptance testing, black box testing and performance acceptance testing, on the other hand, can already be automated. The automation of acceptance tests is accordingly becoming more and more important, as it offers numerous advantages. The most important point here is that the company can be sure that their application works properly from the customer’s point of view.

By using tools like, companies can automate UATs. Automation allows for shortened development times and cost savings, as tests can be performed faster and less manual effort is required. It is also important to ensure that an application works properly in the future. It can also facilitate communication between developers and testers, minimising misunderstandings.

Some examples of automated acceptance tests are checking the login on a website, testing payment processes in e-commerce applications or validating forms in web applications. Using automation not only increases efficiency, but also improves the quality of the software.

When it comes to making your product shine, “integration testing” is the keyword. But wait, it gets better. is the heaven of efficiency, the land of better test coverage and the paradise of lower costs. Sounds like a dream, doesn’t it? Let us show you how this magic works.

In this blog we will look at:

  • what UAT is in the first place,
  • why you should automate it
  • and how you automate UAT.

What is User Acceptance Testing (UAT)?

Imagine you have a great idea for a piece of software. You and your team work hard to bring it to life. But at the end of the day, it’s not just technical brilliance that counts, but also user satisfaction. This is where User Acceptance Testing comes in.

UAT is the last stop before launch. It is the moment when your software is put through its paces by the real user. They simulate real-life scenarios to ensure that the software meets their requirements and works properly.

Why is UAT so Important?

The answer is simple: users are what make your software successful. You could have the best technology in the world, but if your users feel frustrated or confused, all the hard work has been for nothing.

UAT offers the possibility to look at the software from the user’s point of view. Does everything work as it should? Is the user interface intuitive? Are their needs being met? These are the questions to which UAT provides answers.

How Can You Automate UAT?

Imagine if you could run recurring UAT scenarios with a snap of your fingers. The answer? Automation. By freeing the process from human hands and letting algorithms take the wheel, you achieve precision, speed and consistency.

Step by step: UAT automation

1. Identify test cases: Start by identifying the recurring test cases. These are best suited for automation.

2. tool selection: Select the right tool for automation. There are many tools on the market to help you automate your UAT tests.

3. create test scripts: Create scripts that cover the test cases. These scripts simulate the users’ actions and check whether the expected results are achieved.

4. Prepare test data: Prepare test data that will be used in the automated tests. This data should reflect realistic scenarios.

5. Automated execution: Let the magic begin! Run the automated tests and watch as your software is put through its paces.

Review the results of the automated tests. Identify bugs that need to be fixed and analyse the performance of your software.

Efficiency: The Clock of Success

In a world where time is precious, automation could be your secret weapon. Faster results mean faster iterations. As you improve the product, sends your tests on a rollercoaster ride. They come back faster, more thorough than ever before.

UI testing: Cover the User Interface at the Bottom of the Testing Pyramid and Optimise your Software Deve­lop­ment with TaaS.

In today’s agile software development environment, it is essential to deliver high quality software while maximising test coverage. As a product manager and CTO, it’s important to choose the right testing strategy to effectively test your application’s user interface (UI). UI testing is a critical part of the software quality process, but it should not be at the beginning and dominate the testing pyramid. In this article, we’ll look at how you can cover UI testing at the bottom of the testing pyramid, taking advantage of Testing-as-a-Service (TaaS).

Why the Test Pyramid?

The test pyramid is a proven concept introduced by Mike Cohn. It serves as a guide for finding the right balance between different types of tests. The pyramid consists of three layers: Unit tests at the base, followed by integration tests and UI tests at the top. The idea is that the base of the pyramid (unit tests) should contain the largest number of tests, followed by fewer integration tests and even fewer UI tests at the top.

This hierarchy makes for faster test execution as unit tests are isolated and run faster, while UI tests are the slowest as they test the application through the user interface and thus take more time.

The Challenges of UI Testing

UI tests are crucial for ensuring the user experience. They simulate a user’s interaction with the application and check that all components work together seamlessly. However, they also bring some challenges:

  1. Time required: UI testing is time-consuming and can slow down test execution, especially for complex applications or when using traditional testing frameworks.
  2. Maintainability: UI tests are prone to instability due to changes in the user interface, which requires constant adaptation of the tests.
  3. Scalability: As application complexity increases, scaling UI tests can become problematic.

The Solution: UI Tests at the End of the Test Pyramid

To overcome the challenges of UI testing and use the test pyramid effectively, we recommend placing UI tests at the end of the pyramid. Start with the basics by writing unit tests for each individual function. Then run integration tests to ensure that the modules of the application work together properly.

Only then should UI tests be written to check the full interaction of the application. This way you minimise the number of UI tests and optimise the test coverage of your application.

Testing-as-a-Service (TaaS) as a Solution

This is where Testing-as-a-Service (TaaS) comes in. TaaS is a cost-effective and scalable solution for UI testing of your application. With TaaS, you can use specialised testing teams that specialise in UI testing and automated scripts. This saves you the time and resources it would take to build an in-house testing team.

A recommended TaaS tool is “”. With its visual, user-friendly interface and comprehensive testing options, offers an ideal solution for efficiently testing the user interface of your application. It supports UI testing for different platforms and allows seamless integration into your development process.


As a product manager and CTO, it is important to choose the right testing strategy to ensure software quality while optimising test coverage. The test pyramid is a proven concept to place the UI tests at the end and increase the testing speed. With Testing-as-a-Service (TaaS), especially, you can make your app’s UI testing cost-efficient and effective.

Invest in the right tests and tools to gain the trust of your users and deliver high quality software. Your users will thank you for it!
