# Apple Dev MCP - Testing Guide
This document outlines our comprehensive testing strategy to ensure all Apple development content (design guidelines + technical documentation) remains discoverable and accessible through both traditional MCP and Desktop Extension interfaces.
## 🎯 Testing Philosophy
Our testing approach prevents the "0 results" problem by ensuring that:
1. **All major content is discoverable** through natural search terms (design + technical)
2. **User expectations are met** when searching for Apple development concepts
3. **Cross-platform consistency** is maintained across iOS, macOS, watchOS, tvOS, and visionOS
4. **Content fusion works correctly** - design guidelines integrate with technical documentation
5. **Desktop Extension functionality** works seamlessly with traditional MCP integration
6. **Synonym coverage** handles different ways users describe the same concepts
## 📊 Test Results Summary

### 2. Content Validation Tests (`content-validation.test.ts`)
Validates that:
- All content files are discoverable by their primary terms
- Search index accurately represents actual file content
- Platform-specific content is properly filtered
- Relevance scoring works correctly
- Synonyms and alternative terms are handled
### 3. Authentication Search Tests (`authentication-search.test.ts`)
Specifically tests the authentication/login scenarios that were previously failing:
- Critical authentication terms (login, authentication, security)
- Sign in with Apple content discoverability
- Privacy guidelines accessibility
- Component spec functionality
- Search quality validation
### 4. Dynamic Content Discovery Tests (`crawlee-hig.test.ts`)
Tests specific to dynamic content discovery functionality:
- **Recursive page crawling** (2-level depth discovery)
- **Content quality validation** (JavaScript error page detection)
- **Cache performance** (TTL and graceful degradation)
- **Content processing** (HTML to markdown conversion)
- **Apple website compatibility** (SPA architecture handling)
### 5. Quick Coverage Script (`scripts/test-coverage.js`)
Lightweight test that can be run anytime to verify:
- **41 critical search terms** that users commonly look for
- **Platform-specific searches** across all Apple platforms
- **Component specification functionality**
- **Technical documentation integration**
- **Dynamic content discovery performance**
- **Overall discoverability score**

## 🚨 Failure Detection
### What to Monitor
1. **New "0 results" scenarios** when content is added
2. **Relevance score degradation** (scores dropping below thresholds)
3. **Platform filtering issues** (iOS searches returning macOS-only content)
4. **Content discovery failures** (pages not being found or processed)
5. **Cache performance issues** (TTL expiration or degradation problems)
6. **Technical documentation gaps** (missing API docs or broken links)
7. **Synonym gaps** (synonyms not finding related content)
### Automated Alerts
The tests will fail if:
- Any critical search term returns 0 results
- Relevance scores drop below minimum thresholds
- Platform-specific searches fail to find platform content
- Dynamic content discovery process fails
- Content processing returns errors or invalid content
- Technical documentation integration breaks
- Cross-platform consistency is broken
### Coverage Thresholds
- **Critical Terms**: Must maintain 100% coverage
- **Overall Discoverability**: Must stay above 90%
- **Platform Coverage**: All 5 platforms must be searchable
- **Component Specs**: Core components must return content
## 🔄 Continuous Monitoring
### When to Run Tests
1. **Before releases** - Full test suite
2. **After content updates** - Quick coverage check
3. **CI/CD pipeline** - Automated on every change
4. **Monthly health checks** - Comprehensive validation
### Test Data Maintenance
- Update critical terms list as new Apple features are added
- Add new synonym pairs when users report search issues
- Expand platform-specific tests for new OS versions
- Include new Apple technologies in coverage tests
## 🎯 Success Criteria
### ✅ Excellent (95-100%)

### ⚠️ Fair (70-84%)
Significant discoverability issues, needs attention
### ❌ Poor (<70%)
Major search gaps, user experience degraded
## 📈 Future Enhancements
### Planned Improvements
1. **User query analytics** - Track real search patterns
2. **Semantic search testing** - Natural language queries
3. **Performance benchmarks** - Search speed validation
4. **A/B testing framework** - Compare search algorithms
