How to achieve effective Regression Testing?

 



Following are the three key factors that can be implemented to achieve effective regression testing:

1. Strategic management of workforce: This factor is linked with the human resource management that is crucial for carrying out effective regression testing. The team members are strategically managed by the QA manager, whose objective is to encourage and push the team members to do their level best in line with testing activities.

If regression testing is performed by the same tester continuously, then the chances are that the tester will eventually lose interest as the work becomes mundane. So, the QA manager and team leads must make sure that the testers are rotated around certain specific time frames in order to carry out regression testing productively.

2. Effective maintenance of regression test suite: A repository of regression test suites needs to be maintained.Whenever an integration or new change occurs, respective test cases need to be created and then added to the regression test suite. 

Some of the existing test cases can also be moved into the list of regression test cases. All test cases should be maintained and kept in a single place so that at the time of every regression test cycle, they can be executed in a streamlined manner.

Test cases can be qualified for regression test suite based on a certain specific criterion. Test cases should be regularly screened in order to make sure the efficiency and accuracy of test suites. The regression test suite should be optimized by the categorization of test cases into re-testable, reusable and obsolete test cases.

3. Problematic scenarios should be clearly identified: Problematic areas need to be focused and worked upon in order to enhance the process of regression testing. Due to several factors such as clarity of requirements, developer expertise, the difference in complexity level of each module etc., some software modules may have less bugs than others. Bug reports are also a key platform through which assessment can be done like only some modules having a larger number of issues.

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,
