5 regression testing types that you should know

In an age where companies are continuously releasing new updates to their software, regression testing has become more and more essential to a successful software development lifecycle. Yet just like all other areas of software testing, regression testing requires strategic thinking and implementation so that it will provide the most value. There are many different ways to do regression testing, which you can choose based on factors such as the stage of software development or your team’s time and resources.

This infographic offers a brief overview of some of the most common regression testing types:

Corrective regression testing

  • Analyzes the impact of new code on the software’s already existing code
  • Uses a subset of existing test cases to reduce the costs and efforts needed for retesting

Selective regression testing

  • Analyzes the impact of new code on the software’s already existing code
  • Uses a subset of existing test cases to reduce the costs and efforts needed for retesting

Progressive regression testing

  • For when there are new test cases and changes in program specifications
  • Ensures that a new or updated version of your software does not compromise your already existing features

Partial regression testing

  • Tests issues when new code is added to already existing code
  • Ensures that a system in continuing to work after adding new code

Unit regression testing

  • Most important part of unit testing
  • Focuses on the code as a unit, while blocking all associated dependencies & interactions during testing
