Testing user interfaces has always been tricky. The details of UI are nuanced and subjective. “Does this look right?” Co-opting existing testing solutions like unit, E2E, and snapshot tests tends to be brittle and time-consuming.

It turns out to be a pragmatic yet precise way to test component libraries. This presentation goes over why to consider visual testing, what tools are needed, and how it fits into your development process.
