+Feature: create local storage from the command line
+  As an admin
+  I want to list all created local storage from the command line
+  So that I can view available local storage
+
+  Scenario: List the created local storage
+    Given the administrator has created the local storage mount "local_storage2"
+    And the administrator has created the local storage mount "new_local_storage"
+    And the administrator has uploaded file with content "this is a file in local storage" to "/local_storage2/file-in-local-storage.txt"
+    And the administrator has uploaded file with content "new file" to "/new_local_storage/new-file"
+    When the administrator lists the local storage using the occ command
+    Then the following local storage should exist
+      | localStorage      |
+      | local_storage2    |
+      | new_local_storage |
