+## Useful crates for writing tests
+
+Rust comes with only basic support for writing tests.
+
+Here are some additional crates which we recommend for writing tests:
+
+* [googletest](https://docs.rs/googletest): Comprehensive test assertion library in the tradition of GoogleTest for C++.
+* [proptest](https://docs.rs/proptest): Property-based testing for Rust.
+* [rstest](https://docs.rs/rstest): Support for fixtures and parameterised tests.
