<critical_constraints> ❌ NO tests without edge cases ❌ NO generic assertions (assertTrue) → use specific (assertEqual, toEqual) ❌ NO test dependencies → each test must be independent ✅ MUST follow Arrange-Act-Assert (AAA) pattern ✅ MUST mock external dependencies (APIs, DB, filesystem) ✅ MUST use descriptive test names (what + expected outcome) </critical_constraints>
