In what cases is regression testing conducted to verify changes in the application?

Regression testing is conducted in the following cases:

• After making changes to the code (bug fixes, adding new features) to verify that these changes did not break existing functionality.
• When updating dependencies or libraries.
• After refactoring the code.
• When integrating new modules or components.

The goal of regression testing is to ensure that the application works correctly in all previously tested scenarios, despite the changes.
