Test Standards

Refer to test-standards.md for detailed testing guidelines.

Key Principles

1. Test Validity - Tests verify requirements, not implementation details
2. Coverage - Happy path, edge cases, error scenarios, integration points
3. Methodology - Appropriate mocking, test isolation, clean setup/teardown
4. Maintainability - Readable tests, minimal duplication, clear test data

Anti-Patterns to Avoid

• Logic duplication (re-implementing production logic in tests)
• Module-level mocking (prefer fetch-level mocks)
• Private method testing (test through public interface)
• Boundary testing gaps (client-server, null vs undefined)
• Form testing gaps (schema-only tests are insufficient)
