If there are any visual differences, Jest will report them.After running the test, Jest will generate a folder named image_snapshots containing the baseline and compared images. You can review and approve any changes as needed.Remember to replace the URL and adjust the test script to match your specific React component or application. This example demonstrates a basic setup for Visual Regression Testing with Playwright and React, and you can expand upon it to suit your project's needs.if you would like to watch a video, there is another example: https://www.youtube.com/watch?v=Y1eTK-j66PUThank you for taking the time to read the article. let me know in the comments your approach to visual regression testing?HASHTemplates let you quickly answer FAQs or store snippets for re-use.
