What are Regression Testing Tools for Bugzilla?

Regression testing tools are software tools used to detect and fix any functional or technical issues with a program. They are helpful in ensuring that changes to an existing system do not create any unexpected problems. Regression testing tools help find bugs, verify the functionality of a feature, and test for proper integration between components. The primary purpose of regression testing is to ensure that bug fixes work properly, that new features function correctly, and that no new bugs have been introduced with the modification. Regression testing tools can be used for unit tests, end-to-end tests, integration tests, exploratory tests and more.
