" summary

A migration at Docker cuts full test runs by about 6x faster and brings single-test feedback from over five seconds to almost instant by dropping complex wiring and adopting Jest features: immersive watch mode, deep git integration, and the parallelization library jest-worker. Jest exposes small packages like jest-diff and jest-validate, and a runner API plus create-jest-runner lets teams run Mocha, ESLint, Python or custom checks in parallel and combine multiple project configs.
