- No meaningless `assert_ok!()` tests
- Rich assertions with specific expected values

### ✅ Edge Cases & Error Paths
- Empty/null cases tested
- Boundary values tested
- Concurrent operations tested

## 🎓 Key Learnings

### Chicago TDD Best Practices Applied
1. **State-based testing**: Every test verifies observable outputs, not implementation
2. **Real collaborators**: Minimal mocking, maximum use of actual objects
3. **AAA pattern**: Clear structure in every test
4. **Behavior verification**: Tests answer "what does the code do?" not "does the code exist?"

### Test Quality Metrics
- **No meaningless tests**: Every test verifies specific behavior
- **Rich assertions**: Specific expected values, not just `assert!(result.is_ok())`
- **Edge case coverage**: Empty inputs, boundary values, error paths
- **Async safety**: All async tests use `--test-threads=1` for determinism

### Production-Ready Standards
- ✅ No placeholders or `unimplemented!()`
- ✅ No `TODO` comments (all tests complete)
- ✅ No stubs (all tests verify real behavior)
- ✅ All tests have clear documentation
- ✅ All tests follow project conventions

---

## 🔮 Future Enhancements

### Potential Additions (if needed)
1. **Performance Tests**: Benchmark ollama request latency
2. **Load Tests**: Test with concurrent requests (100+ simultaneous)
3. **Retry Logic Tests**: Exponential backoff behavior
4. **Circuit Breaker Tests**: Fault tolerance patterns
5. **Metrics Tests**: Request/response telemetry
6. **Security Tests**: Input sanitization, injection prevention

### Integration Points
- Hook into CI/CD pipeline for automated execution
- Add coverage reporting to track 80%+ target
- Integrate with testcontainers for real ollama instance tests
- Add mutation testing for test quality validation
