Tester Detective

About

Tester Detective is a specialized quality assurance skill for Claude Code that replaces unreliable text searches with precise AST (Abstract Syntax Tree) structural analysis to map test relationships. By analyzing function callers through claudemem, it identifies exactly which tests cover specific logic and highlights high-impact coverage gaps. It is particularly useful for developers and QA engineers who need to audit test quality, find untested edge cases, and prioritize new test creation based on code importance and PageRank metrics.

Key Features

• Automated identification of high-priority untested functions
• PageRank integration to prioritize critical logic gaps
• AST-based caller analysis for precise test-to-code mapping
• Infrastructure mapping for test frameworks, mocks, and utilities
• Detailed test quality reporting and edge case auditing
• 1 GitHub stars

Use Cases

• Auditing an existing test suite to ensure edge cases and error paths are covered
• Mapping complex test infrastructure and helper utilities in large repositories
• Identifying critical business logic that lacks unit or integration tests
