# cargo-nextest

18 Hacker News commenters recommended cargo-nextest and 1 criticized it, November 2025 to November 2026. It was recommended in 3 of 13 months.

**Verdict:** Fast Rust test runner people say cuts test and CI times and just works. Caveat: per-test processes can't share connection pools, and endpoint security software can hang tests.
