Headless is all about facilitating shift-left motion. It enables development teams to get fast feedback on code and increase build efficiency by running atomic tests wherever they’re needed, but especially early in the delivery pipeline. It works by leveraging headless Chrome and Firefox browsers on Linux in a Kubernetes, container-based environment. In other words, you can now put the theory behind shift-left testing into practice and test on every commit. Then you pair that with full cross-browser testing at the end of the development process, and you’ve got a truly holistic testing strategy.
