Is regression testing the same as end-to-end testing?

 


It is a testing method that ensures an update or change introduced in the code does not alter or modify the existing functionalities of the software application. Even a small code change can increase the usage of system resources, reduce page load time and may also slow down the application’s performance.

To avoid such pressing issues, regression testing is performed. Regression testing is performed whenever any new feature has been added or modifications have been done to the application during the software development process.

 

What is end-to-end testing?

End-to-end testing is a testing method that makes sure that the applications behave as expected and that the data flow is maintained for all kinds of processes and user tasks. A real-world scenario is simulated by initiating the testing process from end-user’s perspective.

More detailed test cases are added through which the test coverage is expanded. The test cases are run based on the end-user’s behavior in order to make sure that the application performs correctly.

 

Are regression testing and End-to-end testing the same?

No, regression testing and end-to-end testing are not the same. Following are the differences that will give you a brief idea about the dissimilarity between regression testing and end-to-end testing:

Regression testing

End-to-end testing

This testing method focuses on ensuring that the new changes does not alter the existing functionalities

This testing method focuses on the workflow

 

The flow of business processes is verified by making sure that the changes made to the system do not interfere with the old code’s functionality

The flow of business processes is verified by finding issues associated with the integrations or subsystem

Tests are run directly following a release or a change in programming

Tests are run continuously throughout the SDLC

Already executed test cases will be re-executed

Test cases are created

Testing is performed in a pre-production environment

Testing is performed in a simulated production environment that mimics end-user experience.

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

Image
  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,
