+Feature: Test creation of calendar events in app
+  In order to take advantage of all the calendar features while using the mobile app
+  As a student
+  I need basic to be able to create and edit calendar events in the app
+
+  Background:
+    Given the following "users" exist:
+      | username | firstname  | lastname  | email                |
+      | teacher1 | Teacher    | teacher   | teacher1@example.com |
+      | student1 | Student1   | student1  | student1@example.com |
+    And the following "courses" exist:
+      | fullname | shortname | category |
+      | Course 1 | C1 | 0 |
+    And the following "course enrolments" exist:
+      | user | course | role |
+      | teacher1 | C1 | editingteacher |
+      | student1 | C1 | student |
+
+  Scenario: Create user event as student from monthly view
+    Given I entered the app as "student1"
+    When I press "More" in the app
+    And I press "Calendar" in the app
+    And I press "New event" in the app
+    Then the field "Date" matches value "## now ##%d/%m/%y, %H:%M##" in the app
+    And I should not be able to press "Save" in the app
+
+    # Check that student can only create User events.
+    When I press "Type of event" in the app
+    Then I should not find "Cancel" in the app
+    And I should find "User" within "Type of event" "ion-item" in the app
+
+    # Create the event.
+    When I set the field "Event title" to "User Event 01" in the app
+    And I set the field "Date" to "2025-04-11T09:00+08:00" in the app
+    And I press "Without duration" in the app
+    And I set the field "Description" to "This is User Event 01 description." in the app
+    And I set the field "Location" to "Barcelona" in the app
+    And I press "Save" in the app
+    Then I should find "Calendar events" in the app
+
+    # Verify that event was created right.
+    When I open the calendar for "4" "2025" in the app
+    And I press "Friday, 11 April 2025" in the app
+    Then I should find "User Event 01" in the app
+
+    When I press "User Event 01" in the app
+    Then I should find "Friday, 11 April" in the app
+    And I should find "Starting time: 9:00 AM" in the app
+    And I should find "User event" within "Event type" "ion-item" in the app
+    And I should find "This is User Event 01 description." in the app
+    And I should find "Barcelona" in the app
+    But I should not find "Ending time" in the app
+
+    When I press "Display options" in the app
+    Then I should find "Edit" in the app
+    And I should find "Delete" in the app
+
+    When I close the popup in the app
+    And I press "Barcelona" in the app
+    And I press "OK" in the app
+    Then the app should have opened a browser tab with url "google.com"
+
+  # @todo: Add more Scenarios to test teacher, different values, and creating events from other views (e.g. day view).
