- **Setup Requirements**: Requires the Istio control plane to be initialized with Pilot.

### Ambient Tests

- **Component Focus**: Primarily focuses on Ambient mode components, including `ztunnel`.
- **Setup Requirements**: Requires the Istio control plane to be initialized with `ztunnel` and other ambient components.
