Question

Accepted Answer

Regression testing is the process of retesting a software application to ensure that new code changes have not adversely affected existing functionality.

Regression testing is done to ensure that new code changes do not introduce new bugs or break existing functionality.
It is typically performed after code changes, bug fixes, or new feature additions.
Regression testing should be automated whenever possible to save time and effort.
The regression test suite should include a combination of high-priority test cases, critical functionality tests, and tests for frequently used features.
In our project, we follow a continuous integration approach where regression tests are run automatically after each code commit.
