regressointiin

Regressointiin is a Finnish term that translates to "regression testing" in English. It is a software testing method used to ensure that recent code changes have not adversely affected existing functionality. The process involves re-executing previously run test cases to verify that previously developed and tested software still performs as expected. Regression testing is a crucial part of the software development lifecycle, helping to identify and fix bugs introduced during development or maintenance.

The primary goal of regression testing is to detect and prevent regressions, which are errors that occur when a new change causes a previously working feature to stop functioning correctly. This type of testing is often performed after code modifications, bug fixes, or system upgrades. By systematically testing the affected parts of the software, developers can gain confidence that the changes have not introduced any unintended side effects.

Regression testing can be performed manually or, more commonly, automated. Automated regression tests are particularly valuable because they can be executed quickly and repeatedly, saving time and resources. These automated test suites are designed to cover a wide range of functionalities, ensuring comprehensive coverage. The results of regression testing are then analyzed to identify any failures, which are then addressed by the development team. Implementing a robust regression testing strategy is essential for maintaining software quality and stability over time.
