Install cargo-nextest and run cargo nextest run to execute Rust tests in parallel for faster feedback.
Install cargo-nextest via rustup or cargo install, then replace cargo test with cargo nextest run to execute tests in parallel.
cargo install cargo-nextest
cargo nextest run
This command runs all tests in your workspace using the faster nextest runner, automatically detecting test binaries and executing them concurrently.
cargo-nextest is a faster alternative to the standard Rust test runner. It runs your tests in parallel instead of one by one, significantly reducing wait times. Think of it as upgrading from a single-lane road to a multi-lane highway for your test suite.
