+Feature: Check config variables
+  In order to check Behat resets config variables
+  As a developer
+  I want to see if it does or not
+
+  Scenario: Set a silly admin setting and a real one
+    Given the following config values are set as admin:
+      | config         | value |
+      | sillyvariable  | 666   |
+      | enableoutcomes | 1     |
+
+  @silly2
+  Scenario: Check both admin settings
+    Then config value "enableoutcomes" should be "0"
+    And config value "sillyvariable" should be ""
