To enforce Test-Driven Development in Rust, this Skill guides you through writing a failing test first, implementing minimal code to pass it, and then refactoring. It ensures adherence to the Red-Green-Refactor cycle for maintainable code quality.

Idiomatic Rust testing patterns include using cfg(test) for conditional compilation, leveraging anyhow and thiserror for error handling, and structuring tests with Arrange-Act-Assert workflows to ensure clear, isolated test validation.

Writing a failing Rust test before implementation requires defining expected behavior using the Arrange-Act-Assert pattern. This Skill enforces the TDD step of creating a failing test to validate requirements before writing the actual logic.

Yes, this TDD workflow supports Rust refactoring tasks by ensuring existing tests pass after code modifications. It enforces the Refactor step of the Red-Green-Refactor cycle to maintain code quality without changing external behavior.

You need cfg(test) to isolate test modules from production builds and anyhow or thiserror for idiomatic error management. This Skill integrates these Rust patterns to enforce structured Arrange-Act-Assert test workflows.

TDD requires failing tests before implementation to confirm the test accurately validates new logic. This Skill enforces this TDD step in Rust, ensuring tests fail initially and pass after writing minimal code, guaranteeing correct coverage.
