Testing Guidelines

Name: testing-strategy
Author: block

Unit Tests

Test one thing per test
Use descriptive test names: test_user_creation_fails_with_invalid_email
Mock external dependencies
Keep tests fast and isolated

Integration Tests

Test API endpoints with realistic data
Verify database state changes
Clean up test data after each test
Use test fixtures for common scenarios

Running Tests

# Run all tests
npm test

# Run unit tests only
npm test:unit

# Run integration tests (requires database)
npm test:integration

# Run tests with coverage
npm test:coverage

Test Structure

tests/
├── unit/           # Fast, isolated unit tests
├── integration/    # Tests requiring external services
├── fixtures/       # Shared test data
└── helpers/        # Test utilities

Best Practices

Arrange-Act-Assert: Structure tests clearly
One assertion per test: When possible, test one behavior
Descriptive names: Test names should describe the scenario
No test interdependence: Tests should run in any order
Clean state: Each test starts with a known state

Coverage Goals

Aim for 80%+ line coverage
Focus on critical paths first
Don't sacrifice test quality for coverage numbers
