1. Validation of metrics collection and reporting.
  1. Testing of logging configurations and log collection.
  1. Validation of tracing and distributed tracing setups.
- **Setup**: The main test setup in this folder initializes the Istio control plane with telemetry configurations.

### Helm Integration Tests

- **Location**: `tests/integration/helm`

gateway in a dedicated namespace and restrict access.

For large-scale gateways it is optionally possible to use a dedicated pilot in the gateway namespace.

### Additional test templates

A number of helm test setups are general-purpose and should be installable in any cluster, to confirm
