+Feature: Uninstall ClusterExtension
+
+  As an OLM user I would like to uninstall a cluster extension.
+
+  Background:
+    Given OLM is available
+    And ClusterCatalog "test" serves bundles
+    And ServiceAccount "olm-sa" with needed permissions is available in ${TEST_NAMESPACE}
+    And ClusterExtension is applied
+      """
+      apiVersion: olm.operatorframework.io/v1
+      kind: ClusterExtension
+      metadata:
+        name: ${NAME}
+      spec:
+        namespace: ${TEST_NAMESPACE}
+        serviceAccount:
+          name: olm-sa
+        source:
+          sourceType: Catalog
+          catalog:
+            packageName: test
+            selector:
+              matchLabels:
+                "olm.operatorframework.io/metadata.name": test-catalog
+      """
+    And bundle "test-operator.1.2.0" is installed in version "1.2.0"
+
+  Scenario:  Uninstall ClusterExtension
+    When resource "clusterextension/${NAME}" is removed
+    Then resource "networkpolicy/test-operator-network-policy" is eventually not found
+    And resource "configmap/test-configmap" is eventually not found
+    And resource "deployment/test-operator" is eventually not found
+    And resource "clusterrole/testoperator.v1.2.-37mym6pni2xxmai9n7fmhtbn9i348lx7o619rmf3ypio" is eventually not found
+    And resource "clusterrole/testoperator.v1.2.0-t88i5epjh8oxp4klplhjyrsekwcp92b27w03ayr1ku5" is eventually not found
+    And resource "clusterrolebinding/testoperator.v1.2.-37mym6pni2xxmai9n7fmhtbn9i348lx7o619rmf3ypio" is eventually not found
