+2. Wait few minutes until all components are deployed
+3. run `oc describe KubevirtNodeLabellerBundle`

+4. check status.conditions - it should contain conditions:
+```
+Progressing - False
+Available - True
+Degraded - False
+```
+
+5. the same you can do with KubevirtTemplateValidator and KubevirtCommonTemplatesBundle (this CR will NOT contain degraded condition, because it makes no sense to put it there, because in every iteration templates are "reinstalled")
+
+6. you can of course delete pods and test if it changes conditions (but take in account, every iteration is slow, so when you delete e.g. node-labeller, it can be recreated between the iterations and ansible will not notice that it was deleted).
+The Easiest way is to create e.g. 2 nodes, let node-labeller to be deployed on both nodes and then disable one (`sudo ifconfig eth0 down && sleep 10 && sudo ifconfig eth0 up`)
+and then wait for [300x10 second](https://github.com/MarSik/kubevirt-ssp-operator/pull/76/files#diff-d1fae8c4046ebdb431e9b097881fc1b7R39 I think we should lower this constant) after that it should set conditions:
+```
+Progressing - True
+Available - False
+Degraded - True
+```
