3. Isolation And External Factors:

Remember that the isolated environment should not be affected by any external factors. They include network latency or fluctuations, system updates, or background processes running on the testing machine. These factors may lead to visual error and malfunctioning of the software application. External influences can potentially introduce visual errors and cause malfunctions in the software application.

Ensuring a controlled environment by addressing the factors safeguards the accuracy of the testing results. All the screenshots and visual reports of the testing process will be saved in that specific folder. This will help to perform visual comparisons effectively.

4. Scriptless Test Cases

Visual regression testing on the cloud platform using scriptless test cases is the best approach. Since numerous cloud-based AI tools are available, test automation can be utilized to develop test cases simultaneously. It is because the testing scope of a programmed test case is limited.

But using AI technologies offered by LambdaTest for test case design opens up possibilities for the testing team to consistently cover the testing scope. It will perform visual testing against some test cases, and again, it will recreate the test cases according to the previous result and analysis. This practice will bring the best visual result for your software application.

5. Documentation Of Visual Test Cases

Documentation is a very effective and important practice in any software testing process. In visual regression testing, you need to test and verify the components visually, and here it is important to mark down your observations, bugs, and analysis and work on them accordingly.

For your visual regression tests performed in LambdaTest, you should create clear and succinct test cases and descriptions. 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.

Hope you get an understanding of the best practices for visual regression testing using the cloud and their various aspects after reading this article.
