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 cases that are repeatable and stable are automated.

What is automated regression testing?

Once a change or update takes place in a product, specific automated techniques and tools are used to test the software product from an automated regression testing standpoint. The automation process makes use of specific processes, workflow and test scripts within a regression testing technique. 

The amount of time, cost and other specific resources that are spent on identifying and fixing bugs in a product is considerably reduced through the tactical use of automated regression tests.

The regression testing process is carried out at a faster pace and maximum test coverage is provided at a much lower cost through the regression test automation platform.

Regression test automation best practices:

1. Successful test cases need to be re-run: In an agile scenario, even the successful test cases need to be repeatedly re-run to make sure that the application is able to function properly on a continual basis.

2. Regression test cases should be updated: There should be a constant updation of regression test cases to make sure that the test suite has been updated with the changes that have been recently introduced 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

How do I build automation test framework for regression testing?

 There will be certain projects wherein developing a software product or application is considered to be complicated. Hence, in such scenarios, regression testing can play a significant role as it helps in re-executing test cases to make sure that the changes made in the software do not impact existing functionality or introduce new bugs. A regression test automation framework helps streamline the regression testing process and makes it more effective. In this article, you will get to know how to build a test automation framework for regression testing. What is regression testing? It is a testing method wherein the existing functionalities of the software product or application do not get altered when new changes have been introduced in the code. What is automated regression testing? Regression test cases are automated, so that they can be performed several times and problems with any new build can be identified accordingly. These steps are repeated to make sure that every aspect of th

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,
