How to Perform Automated Visual Regression Testing | LambdaTest

Are you tired of manually performing visual regression testing for your web applications? :yawning_face:

Look no further! :point_down: LambdaTest has the solution to use automated tools to perform visual regression testing for web applications.

As we already know, regression testing aims at verifying the systems changes against any code or feature updates, visual regression testing works on a similar logic but checks on the visual aspects of the software. In other words, it checks on code changes that could break the visual interface of the software.

The implementation of visual regression testing require integration into CI/CD pipeline. Besides, the process requires writing and running tests along with a browser automation framework that replicates the user actions. Furthermore, visual tests work by generating, analyzing, and comparing the browser snapshots for detecting any pixel changes called visual diffs or perceptual diffs or CSS diffs or UI diffs.

To define the process, it can be divided into four easy steps:

Creating test scenarios

Using an automation testing tool

Reviewers to check on the reports generated

Fixing bugs and updating the same through visual checks
