This generates unit tests across Python, JavaScript, TypeScript, Java, and Go by analyzing your source code structure and creating framework-specific test suites. It extracts functions and classes via AST parsing, then outputs pytest or Jest tests with fixtures, mocks, and assertions covering happy paths, edge cases, and error handling. The Python implementation calculates cyclomatic complexity to prioritize what needs testing, and it includes React Testing Library patterns for component tests. You'll want this when bootstrapping test coverage for existing code, though the generated tests are scaffolds that need refinement. The edge case handling is somewhat generic, so expect to add domain-specific assertions yourself. Good for getting to 60% coverage quickly, less so for nuanced business logic validation.
