You should also include comments or annotations to describe the aim and scope of your baselines and screenshots. Additionally, you should preserve and maintain your screenshots and baselines using a version control system or a cloud-based service. Sharing and communicating with the client will help you understand their demand and make the best possible result. 6. Updating The Baseline Updating the baseline is a very crucial step in the visual regression testing process when performed in LambdaTest. It consists of the practice of taking the feedback result and analyzing them. If the result is considerable, you can approve this update in the baseline. And if you think that it is not worth consideration, you can simply reject them. But you need to mention all these in the baseline. It is because this will help you in the future because you can see all your testing logs in the baseline. Mention the changes that were done intentionally, their reasons, and such things. It will also help all the team members have an overview of the changes that are going on in the software testing process. 6. Optimize Testing Coverage And Scope Always remember to prioritize the testing scope for each component, specifically when executing visual regression testing in cloud platforms like LambdaTest. The high-priority components must be paid more attention, and they should be executed with high precision. Use the concept of full-page and component-based screenshots to compare the changes visually by the testing team. Using this practice in visual regression testing will help achieve a better UI experience and enhance the testing results. You can use some advanced features like custom attributes. These attributes help find the elements separately during visual regression testing. Also, you can use the trigger events and DOM concept. These will help to perform the screenshot comparison effectively. 7. Performing Parallel Testing Apart from this, you can leverage parallel test execution in performing visual regression testing in LambdaTest. Executing parallel testing is what makes visual regression testing productive and effective, though, along with those other factors. 8. Learn From Failure It is the final practice that all testers must follow to perform visual regression testing on the cloud and during test automation. Learn from your previous failure. Document the mistakes that you have made previously. Write down the tool feedback and in which specific tool you got some issues performing the testing process. And learn from these highlights. Make your testing goal and work on your failures. This will bring the best result for your software application. Also, it will help in the overall development of the organization as well as the individual tester. You should follow These best practices while performing visual regression testing on the cloud. Conclusion Visual regression testing is mainly used to find any kind of visual malfunctioning and errors in the software. Visual inconsistency is one of the major reasons that lead to decreased number of users of a product. Some of the best practices that every testing team should follow to perform visual regression testing using the cloud are the selection of appropriate tools, using documentation, using AI-based test cases, etc. Various tools can be used to automate testing and perform visual regression testing on the cloud, such as LambdaTest.
