+    And I log in as "admin"
+    And I set the following administration settings values:

+
+  @javascript
+  Scenario: Show activity greyed-out to students when available from date is in future
+    Given I log in as "teacher1"

+    Then I should see "Available from 31 December 2050."
+    And "Test assignment 1" activity should be hidden
