Tast (go/tast)

Tast logo with Go gopher with green rubber PASS stamp

Tast is an integration-testing system for Chrome OS. Its focus is on maintainability, speed, and ease of interpreting and reproducing test results. It supports building, deploying, and running tests. It doesn't implement other functionality like managing labs of devices used for testing, scheduling tests, or storing test results.

To try it out, see the quickstart document. The overview is a good starting point for learning more about how the system is structured.
