+Feature: Viewing participants page in different group modes
+  In order to view my peers
+  As a student
+  I need to be able to browse participants
+
+  Background:
+    Given the following "courses" exist:
+      | fullname     | shortname | summary | groupmode | category |
+      | C1 nogroups  | C1        |         | 0         | 0        |
+      | C2 visgroups | C2        |         | 2         | 0        |
+      | C3 sepgroups | C3        |         | 1         | 0        |
+    And the following "users" exist:
+      | username | firstname | lastname | email                |
+      | student1 | Student   | 1        | student1@example.com |
+      | student2 | Student   | 2        | student2@example.com |
+    And the following "course enrolments" exist:
+      | user     | course | role    |
+      | student1 | C1     | student |
+      | student1 | C2     | student |
+      | student1 | C3     | student |
+      | student2 | C1     | student |
+      | student2 | C2     | student |
+      | student2 | C3     | student |
+    And the following "groups" exist:
+      | name | course | idnumber |
+      | G1   | C2     | C2G1      |
+      | G2   | C2     | C2G2      |
+      | G1   | C3     | C3G1      |
+      | G2   | C3     | C3G2      |
+    And the following "group members" exist:
+      | user     | group |
+      | student1 | C2G1   |
+      | student1 | C3G1   |
+      | student2 | C2G2   |
+      | student2 | C3G2   |
+
+  Scenario: Viewing participants page in a course without group mode
+    When I log in as "student1"
+    And I am on "C1 nogroups" course homepage
+    And I navigate to course participants
+    Then "Student 1" row "Groups" column of "participants" table should contain "No groups"
+    And "Student 2" row "Groups" column of "participants" table should contain "No groups"
+
+  Scenario: Viewing participants page in a course in visible groups mode
+    When I log in as "student1"
+    And I am on "C2 visgroups" course homepage
+    And I navigate to course participants
+    Then "Student 1" row "Groups" column of "participants" table should contain "G1"
+    And I should not see "Student 2"
+    And I click on "Clear filters" "button"
+    And "Student 1" row "Groups" column of "participants" table should contain "G1"
+    And "Student 2" row "Groups" column of "participants" table should contain "G2"
+
+  Scenario: Viewing participants page in a course in separate groups mode
+    When I log in as "student1"
+    And I am on "C3 sepgroups" course homepage
+    And I navigate to course participants
+    Then "Student 1" row "Groups" column of "participants" table should contain "G1"
+    And I should not see "Student 2"
+    And I click on "Clear filters" "button"
+    And "Student 1" row "Groups" column of "participants" table should contain "G1"
+    And I should not see "Student 2"
