cargo-nextest
A next-generation test runner for Rust projects, an alternative to cargo test.
Loved for running very large Rust test suites quickly12 and keeping CI times down.3 The one reported caveat is that its process-per-test approach may make machines running endpoint security tools like CrowdStrike Falcon hang during test runs.4
