cargo-nextest

cargo-nextest is a test runner for Rust projects. It is a replacement for the built-in cargo test command, with a clearer interface and more control over test runs.

It runs each test in isolation, shows results as they finish, and selects tests with a filter language. It can also record test runs, rerun failed tests, and export traces for analysis. The project says it can run up to 3 times faster than cargo test in its benchmarks.

• Per-test isolation for more reliable runs
• Filter language to select the tests you need
• Retries and per-test settings for slow or flaky tests
• JUnit XML output for CI systems
• Setup scripts that run before tests start

Rust developers and teams with large test suites. CI pipelines benefit from its partitioning across workers and its JUnit output.

cargo-nextest is free and open source under the Apache 2.0 license. It can be installed as a pre-built binary or built from source, and it runs on Linux, Mac, Windows and other Unix-like systems. The site notes that versions 0.9.125 through 0.9.149 have a security issue, so use version 0.9.150 or later.
