+Feature: Validate some activity editing has a non-ajax alternative
+  In order to edit the course activities faster
+  As a teacher
+  I need to be able use some edit tools without ajax.
+
+  Background:
+    Given the following "course" exists:
+      | fullname     | Course 1 |
+      | shortname    | C1       |
+      | category     | 0        |
+      | numsections  | 3        |
+      | initsections | 1        |
+    And the following "activities" exist:
+      | activity | name              | intro                       | course | idnumber | section |
+      | assign   | Activity sample 1 | Test assignment description | C1     | sample1  | 1       |
+    And the following "users" exist:
+      | username | firstname | lastname | email                |
+      | teacher1 | Teacher   | 1        | teacher1@example.com |
+    And the following "course enrolments" exist:
+      | user     | course | role           |
+      | teacher1 | C1     | editingteacher |
+
+  Scenario: Activity settings can be accessed without ajax
+    Given I log in as "teacher1"
+    And I am on "Course 1" course homepage with editing mode on
+    When I click on "Edit settings" "link" in the "Activity sample 1" "activity"
+    Then I should see "Assignment name"
+    And I set the field "Assignment name" to "New name"
+    And I press "Save and return to course"
+    And I should see "New name"
+
+  Scenario: Indent an activity can be done without ajax
+    Given I log in as "teacher1"
+    And I am on "Course 1" course homepage with editing mode on
+    And I should not see "Move left"
+    When I click on "Move right" "link" in the "Activity sample 1" "activity"
+    Then I should see "Move left"
+    And I should not see "Move right"
+    And I click on "Move left" "link" in the "Activity sample 1" "activity"
+    And I should not see "Move left"
+    And I should see "Move right"
+
+  Scenario: Hide and show an activity can be done without ajax
+    Given I log in as "teacher1"
+    And I am on "Course 1" course homepage with editing mode on
+    And I should not see "Show" in the ".cm_action_menu" "css_element"
+    When I click on "Hide" "link" in the "Activity sample 1" "activity"
+    Then I should see "Show" in the ".cm_action_menu" "css_element"
+    And I should not see "Hide" in the ".cm_action_menu" "css_element"
+    And I click on "Show" "link" in the "Activity sample 1" "activity"
+    And I should not see "Show" in the ".cm_action_menu" "css_element"
+    And I should see "Hide" in the ".cm_action_menu" "css_element"
+
+  Scenario: Activity visibility with stealth option can be changed without ajax
+    Given the following config values are set as admin:
+      | allowstealth | 1 |
+    And I log in as "teacher1"
+    And I am on "Course 1" course homepage with editing mode on
+    And I should see "Show on course page"
+    And I should see "Hide on course page"
+    And I should see "Make available but don't show on course page"
+    And ".activity-badges" "css_element" should not exist
+    When I click on "Hide on course page" "link" in the "Activity sample 1" "activity"
+    Then I should see "Hidden from students" in the "Activity sample 1" "core_courseformat > Activity visibility"
+    And I should not see "Available but not shown on course page" in the "Activity sample 1" "core_courseformat > Activity visibility"
+    And I click on "Make available but don't show on course page" "link" in the "Activity sample 1" "activity"
+    And I should not see "Hidden from students" in the "Activity sample 1" "core_courseformat > Activity visibility"
+    And I should see "Available but not shown on course page" in the "Activity sample 1" "core_courseformat > Activity visibility"
+    And I click on "Show on course page" "link" in the "Activity sample 1" "activity"
+    And ".activity-badges" "css_element" should not exist
+
+  Scenario: Duplicate activity can be done without ajax
