"""
Comprehensive Test Suite for Synchronous HttpClient

Tests all features and functionality of the HttpClient including:
- HTTP methods (GET, POST, PUT, PATCH, DELETE, HEAD, OPTIONS)
- Authentication (Basic, Bearer, OAuth2, API Key)
- Request/Response handling (JSON, form data, multipart, files)
- Headers and parameters
- Configuration (timeouts, retries, SSL, compression, protocols)
- Error handling and edge cases
- Performance features
