Writing Your First Visual Regression Check in Playwright
Blog post from Checkly
Playwright` is a browser automation framework that enables developers to automate web browsers in order to test their websites and applications. It allows users to write tests using JavaScript, which can be used to compare two screenshots and detect visual regressions. The `maxDiffPixels` setting can be configured to decide how far the current snapshot can vary from the baseline. However, screenshot tests are not portable across different machines due to rendering engine differences. To overcome this, `Checkly`'s visual regression monitoring tools can be used with Playwright, allowing for continuous monitoring of websites and alerts when visual comparison fails. With Checkly, monitors can be run on virtual machines managed by the platform, making it easier for teams to manage their tests as part of a shared repository.
