Title: What are the regression testing examples?
Summary:
Companies all around the world want to achieve reliable software that offers a seamless customer experience. To do so, companies make every effort to create bug-free software. But a new bug isintroduced or an old bug is re-introduced mostly whenever a code change is made, which affects the existing functionality of the software. To make sure that the software doesn't have any defects or bugs, regression testing is used. Let us now understand what exactly is regression testing, why is it needed, what are the approaches and examples of regression testing practice.
Body:
What is regression testing?
Regression testing is a black box software testing type that includes rerunning functional and non-functional tests to verify that a recent code change in the software does not affect the existing
functionalities of the product. This is done to ensure that the product works fine with newfunctionalities, bug fixes, or any changes in the code of the software.
In the regression testing method, previously executed test cases are re-executed to ensure that product remains bug-free and works as expected even after frequent changes.
Why should businesses leverage regression testing?
Businesses can get a lot of benefit by conducting regression tests on their software. Below mentioned are some of the benefits that business can achieve if they adopt regression testing:
Early defect detection – Regression test helps to identify defects early and easily. It check the complete functionality of the software to find defects in the product when any code changes are done.
Early defect fixing –Regression tests helps to fix defects early in the software development lifecycle.
Ensure stability – By automating the regression test, bugs are identified and resolved constantly after every code change, which makes the product bug free and reliable
Ensure business continuity – Automated regression tests free up teams to let them focus on other important tasks. This ultimately helps in ensuring business function continuity.
Ensure faster delivery of quality product – Faster bug identification and fixing help teams to push product faster in the market.
What are some of the examples of regression testing?
Below mentioned are some of the examples of regression testing:
Case- Fixing a defect Consider a scenario where the login button is not working on a login page and a tester reports a bug stating that the login button is not working. Once the developers fix the bug, the tester tests it to make sure the login button is working as expected. Simultaneously, the tester tests other functionality that is related to the login button.
Case - Adding new functionality
Suppose earlier the website allows login only via email, but now a new feature is added which allows login via Facebook also. Now the tester tests that the new functionality works fine and ensures
whether this new functionality has not affected any existing functionality.
Below mentioned are some approaches to regression testing that will help you to understand in what other ways regression testing is done.
Bug regression – In this technique the testers check a specific bug that has been allegedly
fixed
General functional regression – It included running regression test on all areas of software or app to check if recent changes have resulted in code destabilization
Conversion and port testing – It involves running a suite of test cases to ensure that the application has been successfully ported to a new platform.
Conclusion:
Regression testing is an important software testing type that can be done at any stage of SDLC. It helps to ensure the proper functionality of the software. Since the software has to go through constant updates and frequent changes it is very essential to perform effective regression tests after every code change.
Leverage regression testing from a next-gen QA and software testing services provider to get high-quality software that delivers a seamless CX.
