Understanding the Difference Between Retesting and Regression Testing in Software Testing

When it comes to software testing, it's crucial to distinguish between retesting and regression testing to ensure comprehensive quality assurance. Let's delve into the key differences:

Retesting:

Retesting is the process of checking a specific bug fix or a code change made by developers in the software. It involves verifying that the identified defect has been successfully rectified and the related functionality is working as intended. This type of testing focuses on confirming that the issue identified in the earlier stages has been resolved.

Regression Testing:

On the other hand, regression testing aims to ensure that the recent code changes or new features introduced in the software have not negatively impacted the existing functionalities. It involves re-executing previously conducted tests to validate that the modifications made have not caused any unintended side effects or bugs in other parts of the application.

In summary, retesting is specific to validating bug fixes, while regression testing checks for unintended impacts on the overall software functionality due to recent code changes. Both types of testing are vital components of a robust software testing strategy, helping to maintain the quality and reliability of the software product.
