kiertotestit

Kiertotestit, also known as cycle testing or regression testing in software development, is a process of executing a predefined set of test cases to verify that recently implemented changes have not adversely affected existing functionality. The core idea is to ensure that the software, or a specific module within it, continues to work as expected after modifications. This is particularly important in agile development environments where frequent code changes are common.

The term "kiertotestit" implies a cyclical nature, where the testing phase is revisited after each significant development iteration. This helps to catch bugs early in the development lifecycle, reducing the cost and effort required to fix them. The set of test cases used in kiertotestit often includes a combination of critical path tests, core feature tests, and previously identified bug-fix tests. Automation plays a crucial role in efficient kiertotestit, allowing for rapid execution of a large number of tests without manual intervention.

The primary objective of kiertotestit is to maintain software stability and prevent the introduction of new defects. By repeatedly testing the stable parts of the system against new code, development teams can gain confidence in the overall quality of the software. This practice is fundamental to continuous integration and continuous delivery (CI/CD) pipelines, where automated kiertotestit are triggered with every code commit. The results of these tests provide rapid feedback to developers, enabling them to address issues promptly.
