11## AI-Specific Testing Approaches
12 
13### 1. AI Service Mocking
14```typescript
15// Mock AI service responses for consistent testing
16const mockAIService = {
17  complete: jest.fn(),
18  stream: jest.fn(),
19  embed: jest.fn()
20};
21 
22beforeEach(() => {
23  mockAIService.complete.mockResolvedValue({
24    content: 'Mocked AI response',
25    usage: { prompt_tokens: 10, completion_tokens: 20 }
26  });
27});
28```
29 
30### 2. Integration Testing Patterns
31```typescript
32describe('AI Integration Tests', () => {
33  it('handles real AI service responses', async () => {
34    // Use test API keys for integration tests
35    // Test with actual AI services in staging
36    // Validate response formats and data
37    // Handle rate limiting and timeouts
38  });
39  
40  it('gracefully handles AI service outages', async () => {
41    // Test failure scenarios
42    // Validate fallback behaviors
43    // Ensure user experience remains smooth
44  });
45});
46```
47 
48### 3. Performance Testing
49- Monitor AI response times
50- Test under concurrent load
51- Measure token usage and costs
52- Validate memory usage patterns
53 
54### 4. End-to-End Testing
55```typescript
56// Test complete AI workflows
57describe('AI Chat Flow', () => {
58  it('completes full conversation cycle', async () => {
59    // Send user message
60    // Receive AI response
61    // Validate UI updates
62    // Test conversation history
63  });
64});
65```
66 
67### 5. Error Scenario Testing
68- Test API rate limit handling
69- Validate quota exceeded scenarios
70- Test network failure recovery
71- Verify error message display
72 
73### 6. Data Quality Testing
74- Validate AI response formats
75- Test prompt injection prevention
76- Verify content filtering
77- Check for appropriate responses
78 
79### 7. Accessibility Testing
80- Test screen reader compatibility
81- Validate keyboard navigation
82- Check color contrast compliance
83- Test with assistive technologies
