What is Regression Testing in Software

 


Nobody feels excited to do the very same tasks again and again. Unfortunately, regularly upgraded software is highly prone to bugs and mistakes whenever the code is being updated or altered. However, when your software grows, so will the regression test package.

What is Regression Testing?

Regression testing is only executing the existing test cases to make sure that the present functionalities work good. The rise of agile has considerably influenced the testing practices. In the traditional waterfall model evaluation was thought of to be the" last step" before the launch of applications build.

With the rising customer demands for rapid development, the frequency of testing the application has also increased. With every launch the testers will need to make sure the application as a whole is functioning as expected and there are no impacts of this new code that has been placed in which may influence the present working functionalities.

Regression testing, also referred to as verification testing, is the selective retesting of an application system that's been altered to ensure that any bugs are fixed and that no other previously working functions have failed as a result of the reparations and that newly added features haven't created problems with previous versions of the program.

Regression Testing and Patches

Regression testing has been initiated following a developer has attempted to fix a recognized problem or has additional source code to a program which may have inadvertently introduced errors. It's an excellent control measure to ensure that the recently modified code complies with its specified requirements and that unmodified code hasn't yet been affected by the maintenance activity.

This kind of applications retesting is a common approach taken by programmers after stains or bug fixes are developed. Within this situation, regression testing will ensure the changes do not adversely affect the software or system or create problems elsewhere in the application.

Regression testing vs. UAT: Know the difference?

Image
  Regression testing and User Acceptance Testing (UAT) play a key role in developing a quality product. Regression testing ensures that the functionality of the software product or application is working as per the expected requirements, despite changes being made in the code.  User Acceptance Testing is involved in ascertaining whether the product meets business and user-specific requirements. In this article, you will get to know what are the differences between regression testing and user acceptance testing. What is Regression testing Definition? It is a testing method that verifies the new changes made to the code do not alter or modify the existing functionalities. This testing method makes sure that the existing functionalities do not get altered or modified, despite changes being introduced in the code.  Whenever a code change happens during the software application development process, regression testing is performed. This testing method checks the overall functionality an

Regression Test Automation: A Quickstart Guide

  The strategic need to automate regression testing: In many business scenarios, cost and time constraints are faced by organizations due to high-end software development and testing activities. This is because the mobile/web applications need to be thoroughly tested before they are released. When software goes through many changes for a release, there is a possibility for regressions (bugs found in the previous working functionality) to occur. When the functionalities of a software product have regressions then it may scale up the development costs and affect the software release deadlines. For this purpose, regression testing is conducted. But, when regression testing is conducted manually by the team, it consumes a lot of time. Hence, there is a need to automate regression testing.  When regression test cases are automated, the tester's time is saved from checking for regressions that have occurred due to the updates and changes that have been made in the application. Those test

What is the Purpose of Regression Testing?

 What is regression testing? It is a testing method that makes sure that the existing functionalities of the application are working as expected, despite new changes or updates being introduced in the code.  Whenever a new functionality is being incorporated into the application by a developer, soon after, the regression test is initiated by the tester. Following are a few key points that depict the purpose of conducting regression testing: 1. Risks are mitigated: Risks related to changes are identified and mitigated by the regression testing process. Performance degradation, system failures or unexpected issues are prevented, which might otherwise impact user satisfaction and business-related functionalities. 2. Stability is ensured: Regression testing ensures that the software's existing functionalities remain intact despite changes being made to the software product or application. Any unexpected issues or behavior can be detected, which would otherwise impact user experience,
