Native Image Tests
==================

This executes OkHttp's test suite inside a Graalvm image.

The native image runs JUnit 5 tests in the project.

## Testing Strategy

### Unit Tests
- Individual component testing for each feature
- Mock-based testing for protocol interactions
- State machine validation

### Integration Tests
- Feature interaction testing
- Network failure simulation
- Performance benchmarking
- Compatibility testing with Windows Server 2016/2019/2022
