What Are The Differences Between Regression Testing & Retesting?

What is regression testing?

It is a black box type of software testing which is performed to ensure that any recent code change in the software does not affect the existing functionality of the software. It involves re-running functional and non-functional tests to ensure that software works as expected even after frequent code changes.

What is retesting?

It is also known as confirmation testing and is performed to ensure that the defects which were raised during the SDLC (software development life cycle) are fixed and work according to the specifications. During retesting, the failed test cases are re-executed and passed.


Today every enterprise wants quality software and wants to deliver a good UX. Therefore enterprise updates their software from time-to-time. But usually, whenever any change is made, a bug arises in software, or existing functionalities get affected. Also, there are chances that some tests will pass and some will fail, which again need to be tested until they are passed or the bug is fixed. This is where retesting and regression testing play their role. But often people get confused between these two testing types. Therefore we have mentioned the major point of difference between these testing methods. Leverage regression testing from a next-gen QA and software testing services provider to achieve high-quality software.
