How to Automate Regression Testing

 


What is automated regression testing?

Automated regression testing provides an accurate and quick check to make sure that new code changes have not altered the existing features. This testing method ensures that a software product or application is thoroughly verified after any changes have been made.

It’s a testing technique that uses workflows, plans and scripts to improve and speed up the testing process. Through automation, extensive test coverage can be achieved, and regression testing is accelerated.

 

How to automate regression testing?

A computer is involved in interacting with the application as a user would through the test automation process. This means interacting with the UI. There are certain applications that may have been tested via an API or CLI. There are two aspects involved in testing a UI.

Firstly, there is an automated way of choosing and interacting with the UI elements (e.g., text fields, buttons, etc.,). Secondly, the steps need to be run through that make up the test plan.

Selenium can be used in this scenario and is considered a de facto standard for UI testing. The application can be interacted with Selenium WebDriver. A script can be used and written in any language. Web Driver gets the information from the script to know what needs to be selected on the screen and what needs to be done accordingly. For example, the login button can be found and clicked on it.

 

The following are the tools used for automating regression testing:

1. Sahi Pro: It is a robust commercial testing tool designed to provide comprehensive testing solutions and automate web applications. The process of web application testing is simplified by a range of features, including cross-browser compatibility, scripting capabilities and record-and-playback functionality.

 

2. Selenium: It is a popular open-source automation tool for automating web browsers. Selenium WebDriver offers a simple API to interact with web elements, allowing developers to automate tasks like navigating pages, filling forms and clicking buttons.

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...

Regression testing vs. UAT: Know the difference?

  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 fu...

Regression Testing Guide 2020-21

Organizations all across the globe are striving hard to achieve quality software that satisfies their customers. But due to ever-changing customer demands and customer preferences, organizations add new features and upgrade their apps. But these frequent changes and upgrades make the application more prone to bugs and errors. Regression testing is an effective way to deal with such complexities. What is regression testing? Regression testing is an important software testing type in which functional and non-functional tests are re-executed to ensure that existing functionalities of the system remain unaffected and works fine whenever any change is made to the software. It checks whether the previously existing functionalities are working fine or not and identifies bugs in the software if any. When should regression testing be done? • Regression testing should usually be performed whenever any new feature is developed or if any existing feature is improved • Whenever UI updates are made ...
