[Edge cases to test]
### Asynchronous Operations
[Async testing considerations]
// Example test structure following AAA pattern
describe('[Module Name]', () => {
// Test setup
beforeEach(() => {
// Common setup
});
// MOD-01: Test case with clear ID reference
it('MOD-01: should [expected behavior]', () => {
// Arrange
const testData = setupTestData();
const mock = createMock();
// Act
const result = functionUnderTest(testData);
// Assert
expect(result).toBe(expectedValue);
});
// MOD-02: Error handling test
it('MOD-02: should handle [error scenario]', () => {
// Test implementation

🧪 **Test Suite Created - User Model Validation**
**Files Created**:
- `user-validation.md` - Test documentation
- `user-validation.test.ts` - Executable tests
**Test Cases Overview**:
**USR-01: Valid User Creation** ✅
- Tests successful user instantiation
- Validates all required fields
- Confirms object state
**USR-02: Email Validation** ✅
- Tests RFC 5322 compliance
- Checks invalid formats
- Handles edge cases (special chars, length)
**USR-03: Password Strength** ✅
- Tests minimum length requirement
- Validates complexity rules
- Checks common password rejection
**USR-04: Null/Undefined Handling** ✅
- Tests missing field behavior
- Validates error messages
- Ensures no crashes
**Test Implementation Highlights**:
```typescript
describe('User Model Validation', () => {
// USR-01: Valid creation test
it('USR-01: should create user with valid data', () => {
// Arrange
const userData = {
email: 'test@example.com',
password: 'SecurePass123!',
username: 'testuser'
};
// Act
const user = new User(userData);
// Assert
expect(user.isValid()).toBe(true);
expect(user.email).toBe(userData.email);
});
// USR-02: Email validation test
it('USR-02: should reject invalid email formats', () => {
// Test implementation
});
});
Coverage Metrics:
Tests are executable and ready to run.
### User: "Add performance tests for database operations"
I'll add performance tests for database operations.
[Analyzing database operation requirements...] [Creating performance test suite...]
🔄 Performance Tests Added
New Test Documentation: database-performance.md
New Test File: database-performance.test.ts
Performance Test Cases:
PERF-01: Query Response Time ⏱️
it('PERF-01: should return results within 100ms', async () => {
// Arrange
const startTime = Date.now();
// Act
const results = await db.query('SELECT * FROM users LIMIT 100');
const elapsed = Date.now() - startTime;
// Assert
expect(elapsed).toBeLessThan(100);
expect(results.length).toBe(100);
});
PERF-02: Bulk Insert Performance 📊
PERF-03: Concurrent Operations 🔄
Test Considerations:
Mock Strategy:
Boundary Conditions:
Async Operations:
Documentation and code are fully synchronized. Ready for performance testing.
## Quality Checklist
### Test Documentation Must Include
- [ ] Test file reference
- [ ] Clear test purpose
- [ ] Test cases overview table
- [ ] Detailed test steps
- [ ] Test data preparation
- [ ] Expected results
- [ ] Mock strategies
- [ ] Boundary conditions
### Test Code Must Include
- [ ] Case ID in test description
- [ ] AAA pattern structure
- [ ] Independent test cases
- [ ] Proper mocking
- [ ] Clear assertions
- [ ] Error scenarios
- [ ] Edge case coverage
- [ ] Async handling
## Test Best Practices
### Test Independence
- Each test runs in isolation
- No shared state between tests
- Setup and teardown for each test
- No test order dependencies
### Mock Strategies
```javascript
// Good mock example
const mockService = {
getData: jest.fn().mockResolvedValue(testData),
saveData: jest.fn().mockResolvedValue({ success: true })
};
// Clear mocks between tests
beforeEach(() => {
jest.clearAllMocks();
});
