Regressiotesteissä

Regressiotesteissä, often translated as regression testing, is a crucial phase in software development. It involves re-executing previously conducted tests to ensure that new code changes, such as bug fixes or feature additions, have not adversely affected existing functionality. The primary goal is to detect unintended side effects and regressions, confirming that the software still behaves as expected after modifications.

The process typically involves a suite of test cases that cover the core functionalities and critical paths of the application. When new code is introduced, these existing tests are run again. If any of these tests fail, it indicates a regression, meaning a previously working part of the software has broken. Identifying and fixing these regressions is essential for maintaining software stability and quality.

Automated regression testing is widely adopted to make this process more efficient and repeatable. Automation allows for the execution of a large number of test cases quickly and consistently, freeing up human testers to focus on more complex or exploratory testing. This not only speeds up the release cycle but also improves the overall reliability of the software. Without thorough regression testing, the risk of introducing new bugs into a stable system increases significantly.
