GitHub Star Comparison
| No | Name | GitHub Stars | Description | Trend | License | Type | Official Site |
|---|---|---|---|---|---|---|---|
| 1 | built-in testing (標準のテスト機能) | ⭐ 105.1k | Basic testing functionality built into the Rust standard library. Write unit tests using the `#[test]` attribute and run with `cargo test`. Provides simple syntax with assertion macros (assert!, assert_eq!, etc.). | Still used as the foundation for all Rust projects in 2025, with other testing libraries built on top of standard functionality. Combined with Rust's ownership system, enables safe and efficient testing. | Apache-2.0/MIT | Standard Library Testing | Official |
| 2 | quickcheck | ⭐ 2.6k | Automated property-based testing library based on Haskell's QuickCheck. Generates random inputs to test properties and uses shrinking to find minimal counterexamples on failure. Provides a simple and efficient approach. | Continues to be used in 2025 for applications where simplicity and performance are important. More lightweight and faster compared to proptest, but functionally inferior in some aspects, making the choice dependent on use case. | Unlicense/MIT | Property-based Testing Framework | Official |
| 3 | proptest | ⭐ 1.9k | A property-based testing library inspired by Python's hypothesis. Tests properties of code against arbitrary inputs and automatically shrinks to minimal test cases when failures are found. Provides more flexible and advanced shrinking than QuickCheck. | Has become the de facto standard in property-based testing in 2025, adopted by many new projects due to being more feature-rich and flexible than QuickCheck. Features have matured and are stable. | Apache-2.0/MIT | Property-based Testing Framework | Official |
| 4 | rstest | ⭐ 1.4k | A fixture-based testing framework supporting parameterized tests and dependency injection. Efficiently defines multiple test cases using case attributes and supports async tests. Reduces duplication in test code. | Popularity continues to grow in the Rust ecosystem in 2025, particularly valued in projects requiring parameterized tests or complex test setups. Actively maintained with new features being added. | Apache-2.0/MIT | Fixture-based Testing Framework | Official |
