Writing Tests

Core Principles

When writing tests:

1. Use Jest with describe/it blocks
2. Use Effect-TS for async operations (not async/await)
3. Test both valid and invalid cases
4. Add debugging to production code using Effect.logDebug in the code being tested
5. Add debugging to test code using console.log in tests
6. Enable console logging while debugging - Use enableConsoleLogging() and setLogLevel('debug') in beforeEach, then change to setLogLevel('error') when tests are ready
7. Prefer real implementations over mocks - Use real services, managers, and components unless mocking is absolutely necessary
