## Integration Tests High-Level Architecture

### Pilot Integration Tests

- **Location**: `tests/integration/pilot`
- **Purpose**: Tests related to the Istio Pilot component, which is responsible for configuring the Envoy proxies.
- **Focus**:
  1. Configuration of Envoy proxies by Pilot.
  1. Communication between Pilot and Envoy proxies.
