Cargo-nextest: A Next-Gen Rust Test Runner 3x Faster Than Cargo Test
Cargo-nextest: 3x faster than cargo test, per-test isolation, first-class CI
I built Cargo-nextest to solve the speed and reliability issues in Rust testing. It runs up to three times faster than the standard cargo test, offering per-test isolation and a modern interface. With powerful filtering, automatic retries, and first-class CI support, it helps developers identify misbehaving tests and scale their workflows efficiently across Linux, Mac, and Windows.
Treat tests as cattle, not pets.

Thanks for posting about this! I'm the main author of nextest, and it represents my best foot forward for how Rust testing should be done. Happy to answer questions though I might be a bit intermittent.

The "execution model" page[1] is documentation at its best!
It answered 90% of the questions I had at the monent. Thank you!

Super happy user here! It's an excellent piece of engineering.
We're running a fork that supports a "sidecar" server for running multiple integration tests against. So if any tests that need the server are included, it spawns the server, runs the integration tests, and then shuts it down. By re-using the same server we speed up our runs tremendously.

I love nextest, it's been great. This along with bacon catches a lot of issues.

I love nextest. without it my CI could take hours

watch it running 32.5k unit tests without breaking a sweat!
