rstest

rstest is a high-performance testing framework for Rust, built on top of Rspack, designed for developers who need fast, scalable test execution in large codebases. It leverages Rspack's incremental compilation and parallelization to dramatically reduce test run times compared to traditional Rust test runners. Its interest lies in bringing the speed of modern JavaScript bundler-based testing to the Rust ecosystem, enabling near-instant feedback for developers working on complex projects.
