Nextest is one of the very small handful of tools I use dozens or hundreds of times a day. Parallelism can reduce test suite execution time significantly, depending on your project, and has saved me cumulative days of my life. The output is nicer, test filtering is nicer, leak detection is great, and the developer is friendly and responsive. Thanks sunshowers! The one thing we've had to be aware of is that the execution model means there can sometimes be differences in behaviour between nextest and cargo test. Very occasionally there are tests that fail in cargo test but succeed in nextest due to better isolation. In practice this just means that we run cargo test in CI. |

The behavior differences mean some projects (like wgpu, and nextest itself) only support nextest these days. There's also support for setup scripts which can be used to pre-seed databases and stuff.
