Test Quality Standards

Patterns Applied

• AAA Pattern: Arrange, Act, Assert (100% compliance)
• Mocking: Comprehensive API mocking via setup.ts
• Fixtures: Shared test fixtures (mockUserToken, mockItems, etc.)
• Error Handling: Realistic async scenarios and error cases
• Accessibility: Semantic HTML and ARIA compliance checks
• Edge Cases: Empty states, timeouts, validation failures

Code Quality

• Proper cleanup with beforeEach() / afterEach()
• Helper functions for render (reduce duplication)
• Consistent naming conventions
• Type-safe with TypeScript strict mode
• Comments for complex test scenarios
