What are the main stages of regression testing?

Regression testing process typically includes the following stages:

1. Defining the scope of testing — selecting the functionality that may be affected by code changes.
2. Preparing test scenarios — choosing or updating existing test cases that cover critical and changed areas.
3. Executing tests — running the selected tests, manually or through automation.
4. Analyzing results — checking whether tests passed successfully, identifying new defects.
5. Reporting — documenting results and communicating information to the development team.

Regression testing helps ensure that the changes made did not disrupt existing functionality.
