Test-driven development skill for generating tests, analyzing coverage, and guiding red-green-refactor workflows across Jest, Pytest, JUnit, and Vitest. For Test Generation: For Coverage Analysis: For TDD Workflow: When to use other tools: - Capabilities - Workflows - Tools - Input Requirements - Limitations - Provide source code (TypeScript, JavaScript, Python, Java) - Specify target framework (Jest, Pytest, JUnit, Vitest) - Run test_generator.py with requirements - Review generated test stubs - Validation: Tests compile and cover happy path, error cases, edge cases - Generate coverage report from test runner ( npm test -- --coverage ) - Run coverage_analyzer.py on LCOV/JSON/XML report - Review prioritized gaps (P0/P1/P2) - Generate missing tests for uncovered paths - Validation: Coverage meets target threshold (typically 80%+) - Write failing test first (RED) - Run tdd_workflow.py --phase red to validate - Implement minimal code to pass (GREEN) - Run tdd_workflow.py --phase green to validate - Refactor while keeping tests green (REFACTOR) - Validation: All tests pass after each cycle - Source code (file path or pasted content) - Target framework (Jest, Pytest, JUnit, Vitest) - Coverage scope (unit, integration, edge cases) - Coverage report file (LCOV, JSON, or XML format) - Optional: Source code for context - Optional: Target threshold percentage - Feature requirements or...
