+Feature: Enable dashboard setting
+  In order to hide/show dashboard in navigation
+  As an administrator
+  I can enable or disable it
+
+  Scenario: Hide setting when dashboard is disabled
+    Given the following config values are set as admin:
+      | enabledashboard | 0 |
+# 2 = User preference.
+      | defaulthomepage | 2 |
+    When I log in as "admin"
+    And I navigate to "Appearance > Navigation" in site administration
+    Then the field "Enable dashboard" matches value "0"
+    And I should not see "Allow guest access to Dashboard"
+    And I should not see "Dashboard" in the "Start page for users" "select"
+    And I follow "Appearance"
+    And I should not see "Default Dashboard page"
+    And I follow "Preferences" in the user menu
+    And I follow "Start page"
+    And I should not see "Dashboard" in the "Start page" "select"
