+Feature: RandomContext functionality

+  # This will fail on the second scenario if random transforms are not functional.
+  Scenario: Create a first user
+    Given I am at "/user/register"
+    And I fill in "Email address" with "<?user>@example.com"
+    And I fill in "Username" with "<?user>"
+    When I press "Create new account"
+    Then an email has been sent to "<?user>@example.com" with the subject "Account details for <?user>"
