rust-testing

Structure Rust tests by placing unit tests inside cfg(test) modules within your source files and integration tests in a separate tests directory. This separation isolates internal logic from public API boundary tests.

Yes, property-based testing with proptest validates Rust edge cases by automatically generating diverse test inputs to verify invariants. This catches edge cases that manually written unit tests often miss.

Mock components in Rust testing using the mockall crate to isolate dependencies and verify interactions. This allows testing specific module behaviors without executing the actual underlying logic.

Yes, it supports TDD workflows by providing structured testing patterns to guide test-first development. You can scaffold tests, implement Rust functionality, and validate reliability throughout the process.

Test async code paths in Rust using tokio or async-std test runtimes to execute and verify asynchronous operations. This ensures your async functions behave correctly under concurrent execution conditions.

Refactor legacy Rust code with better test guarantees by applying structured unit, integration, and property-based testing patterns. This establishes a reliable safety net before modifying existing logic.
