Verify the Tungsten Fabric deployment

This section explains how to use the tungsten-pytest test set to verify your Tungsten Fabric (TF) deployment. The tungsten-pytest test set is part of the TF operator and allows for prompt verification of the Kubernetes objects related to TF and basic verification of the TF services.

To verify the TF deployment using tungsten-pytest:

If a previous run is still enabled (spec.features.tfTest.enabled is true), disable it first and wait until the tf-test-tungsten-pytest Pod terminates. The operator does not start a new test run while the previous one is enabled.
Enable tfTest in the TFOperator custom resource for the operator to start the Pod with the test set. The tungsten-pytest run is disabled by default:
```
spec:
  features:
    tfTest:
      enabled: true
```
Wait until the tf-test-tungsten-pytest Pod reaches the Running, Succeeded, or Failed state.

To keep track of the tests execution and view the results, run:
```
kubectl -n tf logs -l app=tf-test
```

Optional. The test results are stored in the tf-test-tungsten-pytest PVC. Copy the results before you disable tfTest:

Deploy the Pod with the mounted volume:

# Run pod and mount pvc to it
cat <<EOF | kubectl apply -f -
apiVersion: v1
kind: Pod
metadata:
  name: tf-test-results-pod
  namespace: tf
spec:
  volumes:
    - name: tf-test-data-volume
      persistentVolumeClaim:
        claimName: tf-test-tungsten-pytest
  containers:
    - name: tempest-pvc-container
      image: ubuntu
      command: ['sh', '-c', 'sleep infinity']
      volumeMounts:
        - mountPath: "/tungsten-pytest/data"
          name: tf-test-data-volume
EOF

Copy the results locally:

kubectl -n tf cp tf-test-results-pod:tungsten-pytest/data/results.xml results.xml

Remove the test results Pod:

kubectl -n tf delete pod tf-test-results-pod

Disable tfTest. The operator removes the tf-test-tungsten-pytest Pod:

kubectl -n tf patch tfoperator.tf.mirantis.com <TFOperator CR name> --type='json' -p='[{"op": "replace", "path": "/spec/features/tfTest/enabled", "value": false}]'
