Before being made available to end users, software testing is essential for guaranteeing the quality and dependability of software programs. Retesting and regression testing are two often used phrases among the different testing approaches that are frequently brought up in the context of software testing. Although at first look at these phrases can appear to be identical, they have different meanings in the context of software testing. We shall explore the distinctions between retesting and regression testing below in order to comprehend their importance in software development.

**Retesting**:

Retesting is a software testing technique that focuses on verifying whether a specific defect or issue has been resolved after it has been reported and fixed by the development team. It involves re-executing the same test case that initially identified the defect, but this time with the intention of confirming whether the issue has been successfully rectified. The primary objective of retesting is to ensure that the reported defect no longer exists in the software.

**Regression Testing**:

Regression testing, on the other hand, is a more comprehensive testing approach that ensures new code changes or modifications do not negatively impact the existing functionality of the software. It involves running a set of test cases that cover various aspects of the application to identify any unintended side effects caused by recent code changes. The goal of regression testing is to catch potential regressions unexpected issues that arise due to modifications in the codebase.

Regression testing helps in identifying and addressing such issues before they reach the end-users. Testers execute a predefined suite of test cases to verify that both the modified and unaffected parts of the software are functioning as intended.

**Key Differences**:

**Focus and Scope**:

- Retesting targets specific defects that have been reported and fixed.

- Regression testing examines the overall application to ensure new code changes have not affected existing functionality.

**Objective**:

- Retesting aims to verify the successful resolution of a reported defect.

- Regression testing aims to detect unintended side effects of code changes and prevent regressions.

**Test Cases**:

- Retesting involves executing the same test case that initially exposed the defect.

- Regression testing involves a suite of test cases covering various aspects of the application.

**Timing**:

- Retesting is performed after a defect has been fixed.

- Regression testing is conducted after new code changes or modifications are made.

**Coverage**:

- Retesting has a narrower focus, addressing specific defects.

- Regression testing has a broader focus, covering multiple areas of the application.

**Conclusion**

In the ever-evolving realm of test automation, where precision and efficiency are paramount, the distinction between retesting and regression testing takes center stage.
