Regression testing is the repetitive running of already successfully completed test cases. The intention of regression testing is to verify that modifications and enhancements to a test object do not break the already successfully completed tests.
Implementing modifications within an extensive, unified code base can present inherent challenges. The introduction of new features, bug fixes, or enhancements may potentially impact the operational stability of an application, web-based system, or site. Although automated tests, such as unit tests, serve as a valuable tool for addressing this issue, the following comprehensive resource on regression testing seeks to offer an alternative approach with detailed insights and guidance.
