tdd-assertions

Detecting weak test assertions involves identifying patterns that pass when code is broken, then substituting them with strong, verifiable checks. This skill works across Rust, Python, TypeScript, Go, and Shell to enforce high-quality assertions during test generation and review.

AI assistants systematically produce weak test assertions that pass when code is broken, which is the cardinal sin of TDD. This skill proactively triggers during test generation and review to identify weak patterns and replace them with verifiable assertions.

Strengthening weak assertions across multiple languages requires a cross-language detection tool covering Rust, Python, TypeScript, Go, and Shell. This skill identifies weak patterns and substitutes them with strong, verifiable assertions while providing explanations for each fix.

Yes, this skill supports Go and Shell test frameworks alongside Rust, Python, and TypeScript. It detects and repairs weak assertions across all five languages, ensuring tests fail appropriately when code is broken during test generation, review, and pre-commit flows.

Integrate assertion checking into pre-commit flows by triggering this skill as a mental checklist before committing test code. It detects weak patterns, substitutes strong verifiable assertions, and provides concise explanations for each change during pre-commit, test generation, and review flows.

Review each suggested change rather than blindly applying automated fixes, as this skill provides concise explanations for every substitution to ensure the strong, verifiable assertion fits your specific testing context, language, and framework requirements across Rust, Python, TypeScript, Go, and Shell.
