# Clusterctl test guide

- All controllers tests are to check that all the resources we expect to be created are present in the kubernetes cluster after reconcilation.

- You will set up the according test variables for your own test case and then set up your cluster specs

- Let's use `TestClusterControllerSDSDistributed` as an example from `cluster_controller_test.go`


- First, set up your test function:

```
func (s *Suite) TestClusterControllerSDSDistributed() {

}
```

**Note: for SDS/DSDS cluster, you will need to add `integration.SkipIf(s.Framework)`, but for GKE you won't**

- Set up your test cluster:

```
    cluster := clusterApi.NewCluster(uuid.New().String(),
		s.ProjectID,
		s.Organization,
		fleet.Store,
		clusterConstant.DSDS,
		// for non gke clusters below fields are ignored
		s.Location, "", "", uuid.NewString(), 0, s.Banner)

	s.createCluster(cluster)
	defer s.deleteCluster(cluster)

```

- Check to see if your `shipment(s)` is/are created:


```
    s.checkShipment(cluster)
```

- Check to see if `infra_status` is `READY`:

```
    s.checkInfraStatusDatabaseValue(cluster, edgedb.InfraStatusReady)
```

- Check for cluster namespace creation:

```
    ns := &corev1.Namespace{}
	s.Eventually(func() bool {
		err := s.Client.Get(s.ctx, types.NamespacedName{Name: cluster.Name}, ns)
		return !errors.IsNotFound(err)
	}, s.timeout, s.tick, "expected namespace was never created")

	s.Eventually(func() bool {
		return checkNSOwnerReference(cluster, ns.GetOwnerReferences())
	}, s.timeout, s.tick, "expected namespace owner reference was not found")

```

- Check for `grub` or `grub2 resources` store-credentials plugin:

```
    s.checkHashedGrubSecret(cluster)
```

- Check for `IEN host OS user resources` store-credentials plugin: 

```
    s.checkHashedBreakGlassSecret(cluster)
```

- Verify the cluster you've just created and check if a `DSDS` type created, not a `GKE` type since we're trying to create a dsds one:

```
    gkeCluster := &gkeClusterApi.GKECluster{}
	s.Never(func() bool {
		err := s.Client.Get(s.ctx, types.NamespacedName{Name: cluster.Name, Namespace: cluster.Name}, gkeCluster)
		return !errors.IsNotFound(err)
	}, time.Second, 100*time.Millisecond, "GKECluster should not exits for non-gke clusters")
```
