Question

What is regression testing? Can someone explain with example?

Answer 1

Regression testing is when you select partial or complete executed test cases and re-execute them to ensure proper functionalities. This testing is done to make sure that new code changes do not have any side effects on the existing functionalities. 

These are a few of the use cases of regression testing:

• Test cases which have frequent defects
• Functionalities which are more visible to the users
• Test cases which verify core features of the product
