cargo-nextest is a next-generation test runner for Rust, running tests up to 3x faster than cargo test with per-test process isolation. It includes libraries for core runner logic, metadata, and a filterset expression language, plus first-class CI support with JUnit export and retries.

Use cases

• run Rust tests faster than cargo test
• retry flaky tests automatically
• partition tests across CI workers
• export test results as JUnit XML
• select tests with a filter expression language
• detect and time out slow tests
• stress test by looping over tests many times

When to choose

• you maintain a Rust project with a large or slow test suite
• you need reliable, structured test reporting in CI
• you want per-test isolation, retries, and timeouts
• you need to partition tests across multiple CI machines

When to avoid

• your project is not written in Rust
• you rely on cargo test's shared-process test execution model
• you need a test framework for languages other than Rust
