validate-tests -- Test Anti-Pattern Detection

Corresponding rule: testing.md

Purpose

Statically detect anti-patterns in test code based on behavior-driven testing principles (testing.md). Identify patterns that hurt maintainability, such as implementation-detail testing, excessive mocking, and shared global state.

Input

• Target: test files (*.test.*, *.spec.*, test_*, *_test.*)
• Default search path: entire project. If CLAUDE.md specifies a test directory, that path takes precedence.

Validation Categories

1. Vague Test Names

Detect patterns where test names provide no clue to the cause of failure.
