tdd-guide
Test-first development and test generation for Jest, Pytest, JUnit, Vitest or Mocha: red-green-refactor, fixtures and mocks, coverage gaps. Use whenever the user asks to write tests (before or after the code), mock a dependency or raise coverage.

Test-driven development skill for generating tests, analyzing coverage, and guiding red-green-refactor workflows across Jest, Pytest, JUnit, and Vitest. -- 1. Provide source code (TypeScript, JavaScript, Python, Java) 2. Specify target framework (Jest, Pytest, JUnit, Vitest) 3. Run testgenerator.py with requirements 4. Review generated test stubs 5. Validation: Tests compile and cover happy path, error cases, edge cases 1. Generate coverage report from test runner (npm test -- --coverage) 2. Run coverageanalyzer.py on LCOV/JSON/XML report 3. Review prioritized gaps (P0/P1/P2) 4. Generate missing tests for uncovered paths 5. Validation: Coverage meets target threshold (typically 80%+) 1. Write failing test first (RED) 2. Run tddworkflow.py --phase red to validate 3. Implement minimal code to pass (GREEN) 4. Run tddworkflow.py --phase green to validate 5. Refactor while keeping tests green (REFACTOR) 6. Validation: All tests pass after each cycle -- Input source function (mathutils.py): Command: Generated test output (testmathutils.py): -- Command: Sample output: -- | Tool | Purpose | Usage | |------|---------|-------| | testgenerator.py | Generate test cases from code/requirements |
