In modern software development, software engineers and chief technology officers (CTOs) face the challenge of delivering high-quality products in the shortest possible time and with limited resources. However, to ensure a software project works, a quality assurance team must manually work through checklists step by step, after each change. A slow, expensive and error-prone process. Test automation, on the other hand, can not only speed up the development process, but also reliably ensure the quality of the software. In the following, you’ll learn how.
7 Reasons for Automated Tests
- Faster defect detection: A large number of test cases – far more than would ever be possible through manual testing – are performed in a short time. As a result, potential errors are detected early and can be corrected before they develop into costly problems in production.
- Time savings: Manual tests tie up the development team and require a lot of time and effort. Automated tests run around the clock without human intervention. The development team can thus focus on other critical tasks, resulting in accelerated time to market.
- Repeatability and consistency: Automated tests deliver consistent results because they are always performed according to the same predefined steps. This ensures that the same test conditions are present each time and that potential errors are reproducible, which facilitates their elimination.
- Scalability: As a project grows, automated testing can be easily adapted to meet increasing requirements. New features and modules can be quickly integrated and tested without having to redevelop the entire testing strategy.
- Cost reduction: Early detection and correction of errors through automated tests helps to minimize the costs for subsequent error corrections in the production phase. In the long term, this leads to savings in overall software development spending.
- Improved code quality: Automated tests encourage writing modular, reusable, and well-tested code. Developers must carefully consider how they design their tests, which has a positive impact on the overall quality of the code.
- Confidence in changes: Regularly executed automated tests can provide confidence in changes. Developers and CTOs can be confident that new features or updates will not have unwanted side effects on existing functionality.
Common tests that can be automated
In order to take full advantage of test automation, it is important that the various types of automated tests are integrated into the development process from the very beginning. Common tests during software development include:
- Unit tests, for testing individual code units,- Unit tests, for testing individual code units,
- Integration tests, for testing the interaction between different code units,- Integration testing, for testing the interaction between different code units,
- System tests, for testing the entire software,- System testing, for testing the entire software,
- Regression tests to ensure that changes to the software do not cause new bugs,- Regression testing to ensure that changes to the software do not cause new bugs,
- and user acceptance tests, in which the functionality of the application is checked from the point of view of the target group.- and user acceptance tests, in which the functionality of the application is checked from the point of view of the target group.
Conclusion:
In summary, automated testing leads to faster development, reduced errors, and overall higher code quality, which in turn leads to increased efficiency and competitiveness.
Our automated user acceptance tests alone have saved customers an impressive 40% in testing costs and cut the time-to-market for new features by half. Our test managers analyze customer needs and work with customers to develop tailored test strategies and plans. In this way, we ensure that testing activities meet individual requirements.
