Jest in Strict Mode – Finding and Preventing Flaky Tests

Arthur Buldauskas at React Boston 2019

Have you ever ran into flaky tests? How about tests which pass but should not have? This is a story about how we went about finding these dangerous tests in a suite of over 13,000 tests and what tooling we've built to prevent them from coming back. Hopefully our story and tooling can help you on your own team, big or small.
