+Feature: enable an app
+  As an admin
+  I want to be able to enable a disabled app
+  So that I can use the app features again
+
+  Scenario: Admin enables an app
+    Given the app "comments" has been disabled
+    When the administrator enables the app "comments" using the occ command
+    Then the command should have been successful
+    And the command output should contain the text 'comments enabled'
+    And app "comments" should be enabled
+
+  Scenario: Admin tries to enable an app which is already enabled
+    Given the app "comments" has been enabled
+    When the administrator enables the app "comments" using the occ command
+    Then the command should have been successful
+    And the command output should contain the text 'comments enabled'
+    And app "comments" should be enabled
+
+  Scenario: Admin tries to enable an app which is not installed in ownCloud server
+    When the administrator enables the app "not-installed-app" using the occ command
+    Then the command should have failed with exit code 1
+    And the command output should contain the text 'not-installed-app not found'
+    And the app "not-installed-app" should not be on the apps list
