## Test Coverage

The project includes comprehensive unit tests for all core components:
- `CurlTest`: Tests for static factory methods and basic HTTP operations
- `CurlRequestTest`: Tests for request builder, headers, parameters, body content, SSL, proxies, timeouts
- `CurlResponseTest`: Tests for response handling, status codes, content retrieval, resource management
