Rstest 0.12 adds E2E and Module Federation testing support, speeds up large test suites with VM pools and test environment prebundle, and officially introduces a new JavaScript API.

Rstest 0.11 is a transitional release on the way to 1.0: it breaks and settles the test options, mock, pool, and shard APIs, and also makes V8 coverage faster and aligns fake timers with the latest @sinonjs/fake-timers.

> May 14, 2026 · 9aoy, fi3ework

Rstest 0.10 makes test runs faster and more reliable: a new threads pool, --changed / --related test filters, persistent build cache, memory-aware worker spawn, --trace profiling, and cleaner worker output.
