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 “testup.io”. With its visual, user-friendly interface and comprehensive testing options, testup.io 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 testup.io, 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!
