+Feature: Multi-tab page validation icons
+  As a content author
+  I want to see which tabs have form fields that failed validation
+  So that I know what I need to fix before saving
+
+  Background:
+    Given a "multi tab page" "My MultiTab Page"
+    And a "single tab page" "My SingleTab Page"
+
+  Scenario: I can see tab validation icons on mutli-tab pages
+    Given I am logged in with "ADMIN" permissions
+    And I go to "/admin/pages"
+    And I should see "My MultiTab Page" in the tree
+    And I click on "My MultiTab Page" in the tree
+    When I press the "Save" button
+    Then I can see the form validation error message
+    Then I should not see an invalid tab icon on the "Second" tab
+    Then I should see an invalid tab icon on the "Third" tab
+    Then I should see an invalid tab icon on the "Fourth" tab
+    When I click the "#tab-Root_Third" element
+    And I fill in "Third tab first field" with "abc"
+    When I press the "Save" button
+    Then I can see the form validation error message
+    Then I should not see an invalid tab icon on the "Second" tab
+    Then I should not see an invalid tab icon on the "Third" tab
+    Then I should see an invalid tab icon on the "Fourth" tab
+    When I click the "#tab-Root_Fourth" element
+    And I fill in "Fourth tab first field" with "def"
+    When I press the "Save" button
+    Then I can not see the form validation error message
+    Then I should not see an invalid tab icon on the "Second" tab
+    Then I should not see an invalid tab icon on the "Third" tab
+    Then I should not see an invalid tab icon on the "Fourth" tab
+    When I click the "#tab-Root_Second" element
+    And I fill in "Second tab first field" with "wrong value"
+    When I press the "Save" button
+    Then I can see the form validation error message
+    Then I should see an invalid tab icon on the "Second" tab
+    Then I should not see an invalid tab icon on the "Third" tab
+    Then I should not see an invalid tab icon on the "Fourth" tab
+    When I fill in "Second tab first field" with "222"
+    When I press the "Save" button
+    Then I can not see the form validation error message
+    Then I should not see an invalid tab icon on the "Second" tab
+    Then I should not see an invalid tab icon on the "Third" tab
+    Then I should not see an invalid tab icon on the "Fourth" tab
+
+  Scenario: Tab validation icons dont appear on pages with a single tab
+    Given I am logged in with "ADMIN" permissions
+    And I go to "/admin/pages"
+    And I should see "My SingleTab Page" in the tree
+    And I click on "My SingleTab Page" in the tree
+    When I press the "Save" button
+    Then I can see the form validation error message
+    And I should not see an invalid tab icon on the "Main Content" tab
