# Testing Agent

## Purpose

Automate test execution, coverage reporting, and quality validation across all testing frameworks used in LightSpeed projects.

**Implementation Note:** This agent uses npm scripts defined in `package.json` rather than a dedicated `.agent.js` script file. The workflow executes `npm run check` which orchestrates linting and testing via package.json scripts.

## Responsibilities

- Execute unit tests using Jest for JavaScript/TypeScript
- Run integration tests for API endpoints and services
- Execute E2E tests using Playwright for browser automation
- Run PHPUnit tests for WordPress plugin/theme code
- Execute pytest for Python scripts and automation
- Generate and validate code coverage reports
- Ensure minimum coverage thresholds are met (85% for critical code)
- Report test failures with actionable diagnostics
- Reference [LightSpeed Testing Standards](https://github.com/lightspeedwp/.github/blob/master/.github/instructions/tests.instructions.md)

## Test Frameworks Supported

- **Jest** - JavaScript/TypeScript unit and integration tests
- **Playwright** - End-to-end browser automation testing
- **PHPUnit** - WordPress PHP unit tests
- **pytest** - Python automation and script testing
- **Bats** - Shell script testing

## Workflow Integration

This agent is invoked by the testing workflow (`.github/workflows/testing.yml`) which runs:

```bash
npm run check  # Runs: npm run lint:all && npm run test
```

## Instructions

When activated:

1. Analyze test suite configuration and dependencies
2. Execute all applicable test suites in parallel where possible
3. Collect and aggregate test results and coverage data
4. Identify failing tests and provide diagnostic information
5. Generate coverage reports and validate against thresholds
6. Output a summary with pass/fail status and recommendations
7. Highlight any blocking issues for CI/CD

## Coverage Requirements

- **Critical code paths:** 85% minimum coverage
- **Utility functions:** 80% minimum coverage
- **UI components:** 75% minimum coverage
- **Overall project:** 75% minimum coverage

## Related Workflows

- **testing.yml** - Main test execution workflow (runs `npm run check`)
- **linting.yml** - Code quality checks (runs `npm run lint`)
- **ci.yml** - Comprehensive CI checks (being renamed to testing.yml)

## NPM Scripts

The agent uses these npm scripts:

- `npm run test` - Execute JavaScript tests with Jest
- `npm run test:js` - Jest with coverage and detection options
- `npm run check` - Combined linting and testing

## Best Practices

- Always run tests locally before pushing
- Write tests alongside feature implementation
- Aim for high coverage on critical business logic
- Use meaningful test descriptions and assertions
- Mock external dependencies appropriately
- Keep tests fast and focused
- Update tests when requirements change
