Example-based tests check specific cases you've thought of. Property-based tests let the framework generate hundreds of random inputs and find cases you haven't thought of. For Rust, the proptest crate brings property-based testing with automatic failure shrinking into the standard cargo test workflow.

Rust's built-in #[bench] attribute requires nightly and lacks statistical rigor. Criterion.rs is the de facto standard for benchmarking on stable Rust: it handles warm-up, measures statistical variance, compares runs against baselines, and produces HTML reports. Installation [dev-dependencies] criterion = { version = "0.5", features

cargo-nextest is a next-generation test runner for Rust that replaces cargo test with a process-per-test execution model, better terminal output, built-in retry logic, and significantly faster CI runs. It's a drop-in replacement — your existing tests work unchanged. Why nextest? cargo test runs

Rust ships with a built-in test framework. No extra dependencies, no configuration files — just annotate a function with #[test] and run cargo test. That simplicity is deceptive: the Rust test model covers unit tests, integration tests, doc tests, and benchmarks within a single coherent workflow. This guide covers everything

Rust's borrow checker and type system make certain mocking patterns harder than in dynamic languages, but the mockall crate brings first-class mocking support to Rust's test ecosystem. This guide covers the practical patterns you'll reach for in real projects. Why Mock? Mocks replace
