+Feature: Managers can create courses
+  In order to group users and contents
+  As a manager
+  I need to create courses and set default values on them
+
+  @javascript
+  Scenario: Courses are created with the default forum and blocks
+    Given the following "users" exist:
+      | username | firstname | lastname | email |
+      | teacher1 | Teacher | 1 | teacher1@asd.com |
+      | student1 | Student | 1 | student1@asd.com |
+    And I log in as "admin"
+    And I create a course with:
+      | Course full name | Course 1 |
+      | Course short name | C1 |
+    And I enrol "Teacher 1" user as "Teacher"
+    And I enrol "Student 1" user as "Student"
+    And I log out
+    When I log in as "teacher1"
+    And I follow "Course 1"
+    Then "Latest news" "block" should exist
+    And I follow "News forum"
+    And "Add a new topic" "button" should exist
+    And "Forced subscription" "link" should not exist
+    And I log out
+    And I log in as "student1"
+    And I follow "Course 1"
+    And I follow "News forum"
+    And "Add a new topic" "button" should not exist
+    And I should see "Forced subscription" in the "Administration" "block"
