## 🧪 Test Characteristics

### Modern Async/Await Patterns
✅ All tests use `async/await` syntax
✅ No `done()` callbacks
✅ Proper Promise handling
✅ Error assertions with `expect().rejects.toThrow()`

### Proper Mocking
✅ Event emitter mocking
✅ Simulated API delays
✅ Randomized test data
✅ No external API calls in tests

### Best Practices
✅ **Isolated Tests** - Each test is independent
✅ **Fast Execution** - All tests < 10s total
✅ **Descriptive Names** - Clear test intentions
✅ **Arrange-Act-Assert** - Structured test flow
✅ **Edge Case Coverage** - Boundary conditions tested

## 🎨 Test Examples

### Example: Event-Driven Test
```typescript
it('should emit iteration events', async () => {
  const session = new DSPyTrainingSession(config);
  const iterationResults: any[] = [];

  session.on('iteration', (result) => {
    iterationResults.push(result);
  });

  await session.run('Test iterations', {});

  expect(iterationResults.length).toBe(6);
  iterationResults.forEach(result => {
    expect(result.modelProvider).toBeDefined();
    expect(result.quality.score).toBeGreaterThan(0);
  });
});
```

### Example: Async Error Handling
```typescript
it('should handle errors gracefully in training', async () => {
  const session = new DSPyTrainingSession({
    models: [], // Invalid
    optimizationRounds: 2,
    convergenceThreshold: 0.95
  });

  await expect(session.run('Test error', {})).rejects.toThrow();
});
```

### Example: Performance Test
```typescript
it('should complete within reasonable time', async () => {
  const generator = new SelfLearningGenerator(config);
  const startTime = Date.now();

  await generator.generate({ prompt: 'Performance test' });

  const duration = Date.now() - startTime;
  expect(duration).toBeLessThan(2000);
});
```

## 🔍 Coverage Gaps & Future Improvements

### Current Gaps (Will achieve 75-85%)
- Complex error scenarios in training
- Network timeout edge cases
- Very large dataset handling

### Future Enhancements
1. **Snapshot Testing** - For output validation
2. **Load Testing** - For stress scenarios
3. **Visual Regression** - For CLI output
4. **Contract Testing** - For API interactions
