+Feature: Displaying the link to the Participants page
+  In order to see the course / site participants
+  As a student / admin respectively
+  I need a link to the Participants page be displayed (but only if I can access that page)
+
+  Background:
+    Given the following "users" exist:
+      | username | firstname | lastname | email                |
+      | student1 | Student   | One      | student1@example.com |

+    And the following "courses" exist:
+      | fullname | shortname |
+      | Course1  | C1        |
+    And the following "course enrolments" exist:
+      | user     | course | role    |
+      | student1 | C1     | student |
+
+  @javascript
+  Scenario: Course participants link is displayed to enrolled students after expanding the course node
+    When I log in as "student1"
+    And I expand "C1" node
+    Then "Participants" "link" should exist in the "Navigation" "block"
+    And I navigate to "Participants" node in "My courses > C1"
+    And I should see "Participants"
+    And "Student One" "link" should exist
+    And "Student Two" "link" should not exist
+
+  Scenario: Site participants link is displayed to admins
+    When I log in as "admin"
+    Then "Participants" "link" should exist in the "Navigation" "block"
+    And I navigate to "Participants" node in "Site pages"
+    And I should see "Participants"
+    And "Student One" "link" should exist
