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-cli provides a clean facade for chiga-core. The regression testing of a given url and creating a fresh reference item beforehand. Chigai-cli is designed to be used in your favourite build script.
Provide a url and options such as the viewport width (default: 1024), viewport height (default: 720) or a threshold (default: 0.01 = 1%) for the image comparison. Chigai-cli creates a new screenshot of the whole page and compares it to the last specified reference. If their difference is lower than the given threshold it will exit with 0``, otherwise 1```.
If you know you changed the layout, just set a new reference item before running the tests again.
