Welcome to the home page for cargo-nextest, a next-generation test runner for Rust projects.
- Clean, beautiful user interface. Nextest presents its results concisely so you can see which tests passed and failed at a glance.
- Up to 60% faster than cargo test. Nextest uses a state-of-the-art execution model for faster, more reliable test runs.
- Identify slow tests. Use nextest to detect tests that take a long time to run, and identify bottlenecks during test execution.
- Designed for CI. Nextest addresses real-world pain points with continuous integration scenarios.
- Use pre-built binaries for quick installation.
- Set up CI-specific configuration profiles.
- Reuse builds and partition test runs across multiple CI jobs. (Check out this example on GitHub Actions).
- Automatically retry failing tests, and mark them as flaky if they pass later.
- Print failing output at the end of test runs.
- Output information about test runs as JUnit XML.
- Cross-platform. Nextest works on Linux and other Unixes, Mac and Windows, so you get the benefits of faster test runs no matter what platform you use.
- ... and more coming soon!
Install cargo-nextest for your platform using the pre-built binaries.
Run all tests in a workspace:
cargo nextest run
For more detailed installation instructions, see Installation.
Note: Doctests are currently not supported because of limitations in stable Rust. For now, run doctests in a separate step with
cargo test --doc.
