SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Identifies and eliminates "test theater" anti-patterns in tests, ensuring tests verify real behavior rather than just producing a passing verdict.

Core Features & Use Cases

Anti-Patterns Catalog: Detects meaningless error checks, brittle timing, shallow validation, redundant coverage, and thread-safety theater.
Quality Testing Patterns: Provides concrete examples for deterministic async testing, proper coordination, and data integrity checks.
Language Considerations: Guidance tailored to common languages (Go, Rust, Python, etc.) as appropriate.

Quick Start

Ask Claude to review a test suite and identify anti-patterns, along with concrete improvements and example of improved tests.
