About this tag
Regression testing on WindowsForum.com covers the practice of re-running tests to ensure that new updates, patches, or feature changes do not break existing functionality. Discussions include Microsoft's Image Transform AI update KB5066124 for Copilot+ Windows 11, where regression testing helps verify that incremental improvements to inpainting and image-editing features do not introduce new bugs. Another thread examines a Windows 11 beta bug that unexpectedly reintroduced the Vista startup sound, highlighting how regression testing can catch unintended changes. A third thread details an Outlook CPU crash caused by a faulty update, underscoring the importance of regression testing in preventing business continuity issues. Finally, automated testing via WebDriver for Microsoft Edge is discussed as a method to perform regression testing on web applications.
