    Retesting vs Regression Testing: What’s the Difference?

    JibonBy JibonApril 9, 2023Updated:April 9, 2023No Comments2 Mins Read

    Software testing is an essential part of the software development life cycle. It ensures that the software meets the requirements and is functioning as expected. There are different types of testing, including functional testing, performance testing, security testing, and others. Two common types of testing are retesting and regression testing, but what’s the difference between them?

    Retesting:
    Retesting is the process of re-executing the failed test cases after the defects are fixed. It ensures that the defects identified in the previous testing phase are resolved and that the software is now functioning as expected. The goal of retesting is to ensure that the specific issue that caused the initial failure has been fixed and is no longer causing issues. Retesting is usually performed after the bug is fixed and the new code is integrated into the software.

    Regression Testing:
    Regression testing is the process of testing the software to ensure that the existing functionality has not been impacted by the changes or new features added in the software. It is performed after any change in the software, such as bug fixes, new feature addition, or code refactoring. Regression testing ensures that the changes or new features did not break the existing functionality of the software. It is essential to perform regression testing to ensure that any new changes or features do not have any unintended consequences on the existing features.

    Difference between Retesting and Regression Testing:
    Retesting and regression testing are different types of testing, but they are often confused with each other. The main difference between them is that retesting focuses on testing a specific issue that caused the failure, whereas regression testing focuses on testing the overall software functionality after any changes.

    Retesting is performed after the bug is fixed, while regression testing is performed after any change or new feature addition in the software. Retesting is usually done manually, while regression testing can be automated. Retesting has a narrower scope, whereas regression testing has a broader scope.

    In summary, retesting and regression testing are both crucial types of testing that ensure the software’s quality and functionality. Retesting focuses on testing a specific issue that caused the failure, while regression testing focuses on testing the overall software functionality after any changes. Both types of testing are essential to deliver high-quality software to the end-users.
