Many testing aspirants have difficulty in understanding the difference between regression testing and retesting. In this blog, we are going to look into the key difference between these two types of testing. Also, we are going to learn more about the relationship between regression testing and retesting.
So, let’s try to answer the question
“What is the difference between Regression Testing and Retesting?”
Regression Testing is a type of software testing executed to ensure whether a code change/update/release/patch has not unfavorably disturbed current features & functions of an application.
Re-testing is a type of testing performed to check whether test cases that were unsuccessful in the final execution are successfully passed after the defects are repaired.
In the Regression Testing, the test cases are extracted from functional testing to ensure that no new defects are included due to the software update/change & to check whether original features and functionality are working as expected. Regression testing also ensures that no new defect is introduced to the system. Once the regression test suite is created, the test cases can be automated using automation tool but the same is not applicable for Re-testing.
Jumping into the detailed comparison
In regression testing, the defect logged by tester while testing the software application is fixed by the developer. In Retesting the same defect is checked to make sure whether the defect is fixed or not using steps to reproduce mentioned in the defect.
