+  Scenario Outline: try to download an image preview when the maximum thumbnail input value in the environment is set to a small value
+    Given the following configs have been set:
+      | config                               | value |
+      | THUMBNAILS_MAX_INPUT_IMAGE_FILE_SIZE | 1KB   |
+      | THUMBNAILS_MAX_INPUT_WIDTH           | 200   |
+      | THUMBNAILS_MAX_INPUT_HEIGHT          | 200   |
+    And using <dav-path-version> DAV path
+    And user "Alice" has uploaded file "filesForUpload/testavatar.jpg" to "/testimage.jpg"
+    When user "Alice" downloads the preview of "/testimage.jpg" with width "36" and height "36" and processor thumbnail using the WebDAV API
+    Then the HTTP status code should be "403"
+    And the value of the item "/d:error/s:message" in the response should be "thumbnails: image is too large"
+    Examples:
+      | dav-path-version |
+      | old              |
+      | new              |
