Have you ever spent hours on perfecting a UI, only to have it break in subtle ways by later regressions? Small details like positioning, borders and colours might get changed in subtle ways, and gradually get out of control. With automated visual regression testing, you’ll catch all these kinds of issues, reducing tedious and error-prone manual testing. What a participant will get out of my presentation: * Get to know about what visual regression testing is. * Understand the basics through a hands-on demonstration using Playwright's web browser-based end-to-end tests, and Percy. * When to use these kinds of tests; where it saves time and improves software robustness.
