Modern visual regression testing with puppeteer and blink-diff
Visual regression testing: compare your current state against your baseline. It's nothing new. We've done this for ages. Comparing two images. Looking at the current version and the previous one. Searching for the difference. On our own. Manually.
Well, Chiagi does this automatically. It takes a screenshot from a given URI and compares it to the previous version.
Chigai is designed to be used in your tests. You can use it in your favourite testrunner. As a regression tool. If your layout changes, it won't go on unnoticed.
Chigai uses the chigai-mock-server module for running tests against a deterministic url. It provides one endpoint for static, never changing content. It provides one endpoint for random changing content.
