To write unit tests in Rust, define a `#[cfg(test)]` module with test functions calling the target code and asserting expected behavior. This isolates tests from production builds while validating core library functions.

The RED-GREEN-REFACTOR cycle in Rust TDD involves writing a failing test first, writing minimal code to make it pass, and then refactoring. This workflow promotes robust, maintainable code through structured patterns.

Rust integration tests evaluate the public API of your library by placing test files in a top-level `tests` directory. This separates integration testing from internal unit tests to ensure external behavior correctness.

Yes, you can implement property-based tests and async tests in Rust. This Skill provides testing strategies and example patterns to handle asynchronous code execution and validate properties across generated inputs.

Best practices for organizing Rust tests involve using structured patterns for unit, integration, async, and property-based tests. Following these guidelines streamlines test writing and enables developers to create robust, maintainable code.
