+@availability @availability_dedicationtime
+Feature: availability_dedicationtime
+  In order to control student access to activities
+  As a teacher
+  I need to set dedicationtime conditions which prevent student access
+
+  Background:
+    Given the following "courses" exist:
+      | fullname | shortname | format | enablecompletion | numsections |
+      | Course 1 | C1        | topics | 1                | 3           |
+    And the following "users" exist:
+      | username |
+      | teacher1 |
+      | student1 |
+    And the following "course enrolments" exist:
+      | user     | course | role           |
+      | teacher1 | C1     | editingteacher |
+      | student1 | C1     | student        |
+    And the following "activities" exist:
+      | activity | course | name  |
+      | page     | C1     | P1    |
+      | page     | C1     | P2    |
+      | page     | C1     | P3    |
+
+  @javascript
+  Scenario: Test condition
+    # Basic setup.
+    Given I am on the "P1" "page activity editing" page logged in as "teacher1"
+    And I expand all fieldsets
+    And I click on "Add restriction..." "button"
+    Then "Dedication time" "button" should exist in the "Add restriction..." "dialogue"
+
+    # Add a Page P2 with a dedicationtime condition for 5 minutes.
+    And I am on the "P2" "page activity editing" page
+    And I expand all fieldsets
+    And I click on "Add restriction..." "button"
+    And I click on "Dedication time" "button" in the "Add restriction..." "dialogue"
+    And I click on ".availability-item .availability-eye img" "css_element"
+    And I set the field "Dedication time" to "5"
+    And I set the field "Dedication time unit" to "minutes"
+    And I press "Save and return to course"
+
+    # Add a Page P3 with a dedicationtime condition for 2 hours.
+    And I am on the "P3" "page activity editing" page
+    And I expand all fieldsets
+    And I click on "Add restriction..." "button"
+    And I click on "Dedication time" "button" in the "Add restriction..." "dialogue"
+    And I click on ".availability-item .availability-eye img" "css_element"
+    And I set the field "Dedication time" to "2"
+    And I set the field "Dedication time unit" to "hours"
+    And I press "Save and return to course"
+
+    # Log back in as student.
+    When I am on the "Course 1" "course" page logged in as "student1"
+    
+    # No pages should appear yet.
+    Then I should not see "P2" in the "region-main" "region"
+    And I should not see "P3" in the "region-main" "region"
