+Feature: Required plugins
+In order to customise mahara we can turn off/on plugins
+As an admin
+I check that the plugins are activated/deactivated
+
+Background:
+    Given the following plugins are set:
+    | plugintype | plugin | value |
+    | blocktype  | annotation | 0 |
+    | artefact   | plans | 0 |
+
+Scenario: Checking that we can turn on/off plugins
+    Given I log in as "admin" with password "Kupuh1pa!"
+    And I choose "Plugin administration" in "Extensions" from administration menu
+    Then I should see "Show" in the "annotation/annotation" row
+    Then I should see "Show" in the "plans " row
+    Then I should see "Show" in the "plans/plans" row
+    Given the following plugins are set:
+    | plugintype | plugin | value |
+    | artefact   | plans | 1 |
+    Then I should see "Hide" in the "plans " row
+    Then I should see "Hide" in the "plans/plans" row
