TDD Guide

Test-driven development skill for generating tests, analyzing coverage, and guiding red-green-refactor workflows across Jest, Pytest, JUnit, and Vitest.

Capabilities

Capability	Description
Test Generation	Convert requirements or code into test cases with proper structure
Coverage Analysis	Parse LCOV/JSON/XML reports, identify gaps, prioritize fixes
TDD Workflow	Guide red-green-refactor cycles with validation
Framework Adapters	Generate tests for Jest, Pytest, JUnit, Vitest, Mocha
Quality Scoring	Assess test isolation, assertions, naming, detect test smells
Fixture Generation	Create realistic test data, mocks, and factories

Workflows

Generate Tests from Code

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

Analyze Coverage Gaps

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%+)

TDD New Feature

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

Tools

Tool	Purpose	Usage
`test_generator.py`	Generate test cases from code/requirements	`python scripts/test_generator.py --input source.py --framework pytest`
`coverage_analyzer.py`	Parse and analyze coverage reports	`python scripts/coverage_analyzer.py --report lcov.info --threshold 80`
`tdd_workflow.py`	Guide red-green-refactor cycles	`python scripts/tdd_workflow.py --phase red --test test_auth.py`
`framework_adapter.py`	Convert tests between frameworks	`python scripts/framework_adapter.py --from jest --to pytest`
`fixture_generator.py`	Generate test data and mocks	`python scripts/fixture_generator.py --entity User --count 5`
`metrics_calculator.py`	Calculate test quality metrics	`python scripts/metrics_calculator.py --tests tests/`
`format_detector.py`	Detect language and framework	`python scripts/format_detector.py --file source.ts`
`output_formatter.py`	Format output for CLI/desktop/CI	`python scripts/output_formatter.py --format markdown`

Input Requirements

For Test Generation:

Source code (file path or pasted content)
Target framework (Jest, Pytest, JUnit, Vitest)
Coverage scope (unit, integration, edge cases)

For Coverage Analysis:

Coverage report file (LCOV, JSON, or XML format)
Optional: Source code for context
Optional: Target threshold percentage

For TDD Workflow:

Feature requirements or user story
Current phase (RED, GREEN, REFACTOR)
Test code and implementation status

Limitations

Scope	Details
Unit test focus	Integration and E2E tests require different patterns
Static analysis	Cannot execute tests or measure runtime behavior
Language support	Best for TypeScript, JavaScript, Python, Java
Report formats	LCOV, JSON, XML only; other formats need conversion
Generated tests	Provide scaffolding; require human review for complex logic

When to use other tools:

E2E testing: Playwright, Cypress, Selenium
Performance testing: k6, JMeter, Locust
Security testing: OWASP ZAP, Burp Suite
