Hi @jkdowdle, Thanks for testing the latest alpha. This is an intentional change. jest did not support watch mode and coverage at the same time last year, so the previous behavior of yarn test --coverage did not run in watch mode.

Now that jest supports --coverage flag in watch mode, the following behaviors are supported by default: yarn test --coverage which runs jest in watch mode and prints coverage of the touched files yarn test --coverage --watchAll=false which runs jest in non-watch mode and prints coverage of all files.
