Explore Key 10 Difference between Retesting and Regression Testing
When it comes to software testing, two important terms often mentioned are retesting and regression testing. While they might sound similar, they serve distinct purposes in ensuring the quality and reliability of software applications. Let’s delve into the ten key difference between retesting and regression testing in simpler way that will help you to understand.
10 Difference between Retesting and Regression Testing
Purpose: Retesting is done with the intention of confirming whether a particular flaw or problem has been fixed after being reported and fixed. Regression testing, on the other hand, checks to make sure that any updates or modifications to the software haven’t resulted in any unintended side effects.
Scope: The scope of the retest is the particular functionality or area where the problem was found and fixed. Regression testing, on the other hand, involves testing the entire system or application to find any fresh flaws that might have appeared as a result of recent changes.
Test Cases: Retesting entails running only the test cases that were unsuccessful in the initial run to see if the problem has been fixed. Regression testing involves running a broad range of test cases to make sure all current functionalities are still operating as intended.
Timeframe: Retesting is typically done right away after the identified problem has been fixed. On the other hand, regression testing is carried out at various times throughout the software development lifecycle, such as following the addition of new features or during system integration.
Test Data: The same input data that was used to first identify the flaw is used when retesting. Regression testing, however, needs a wide range of test data to account for various scenarios and guarantee that the changes made haven’t negatively impacted the functionality that already exists.
Automation: Because retesting only requires a small number of test cases, it can frequently be done by hand. On the other hand, because it necessitates repeatedly running a large number of test cases, regression testing frequently benefits from automation tools.
Focus on Defects: Retesting aims to confirm that the particular problem has been fixed and is no longer present. Regression testing is concerned with finding any new problems or flaws brought about by recent changes, even if they have nothing to do with the original problem.
Execution Frequency: Retesting is a one-time task carried out following the resolution of a defect. The iterative process of regression testing is carried out frequently over the course of the software development lifecycle.
Documentation: Retesting documentation is primarily concerned with finding the root cause of the problem and validating the solution. Regression testing documentation gives details on the test cases that were run, the test scenarios that were used, and any flaws that were found.
User Perspective: Retesting addresses the user’s concerns and validates their experience, according to the user’s perspective. Regression testing makes sure that despite the introduction of new changes, the overall user experience is maintained.
Software development teams can efficiently plan and carry out their testing strategies to ensure the delivery of high-quality software that satisfies user expectations and functions dependably in a variety of scenarios by understanding these ten difference between retesting and regression testing.
