## Coverage Summary
**Total New Test Files Created**: 6
**Total Existing Test Files Enhanced**: 3
**Total New Test Methods**: 134+
## Key Testing Features
1. **Comprehensive Security Testing**: Path traversal, input validation, API key checking
2. **Edge Case Coverage**: Empty inputs, None values, invalid JSON, error conditions
3. **Integration Points**: Model providers, tool execution, streaming interfaces
4. **Async Testing**: Web runtime endpoints with async/await patterns
5. **Mock Usage**: Proper mocking of external dependencies (API clients, file I/O)
6. **Parallel Execution**: Testing concurrent tool execution
7. **Streaming Verification**: Delta chunks, done flags, tool results
## Best Practices Followed
- Descriptive test names that explain what is being tested
- Proper setup and teardown in setUp methods
- Use of unittest.mock for external dependencies
- Testing both happy paths and error conditions
- Consistent test structure across all files
- Documentation strings for test classes and methods
- Appropriate assertions for each test case
- Edge case coverage (empty, None, invalid inputs)
- Security-focused tests (path traversal, injection)
