Regression Testing

Regression Testing

Whenever a change in a software application is made, it is quite possible that other areas within the application have been affected by this change. Regression testing is performed to verify that a fixed bug hasn't resulted in another functionality or business rule violation. The intent of regression testing is to ensure that a change, such as a bug fix should not result in another fault being uncovered in the application.

Regression Testing Is Important Because Of The Following Reasons −

• Minimize the gaps in testing when an application with changes made has to be tested.
• Testing the new changes to verify that the changes made did not affect any other area of the application.
• Mitigates risks when regression testing is performed on the application.
• Test coverage is increased without compromising timelines.
• Increase speed to market the product.
