+Feature: enforce password on public link
+  As a user
+  I want to enforce passwords on public links shared with upload, edit, or contribute permission
+  So that the password is required to make changes to the shared resources
+
+  Background:
+    Given the config "OCIS_SHARING_PUBLIC_WRITEABLE_SHARE_MUST_HAVE_PASSWORD" has been set to "true"
+    And these users have been created with default attributes and without skeleton files:
+      | username |
+      | Alice    |
+    And user "Alice" has uploaded file with content "test file" to "/testfile.txt"
+
+
+  Scenario: user tries to update a public link to edit permission without a password when enforce-password is enabled
+    Given user "Alice" has created a public link share with settings
+      | path        | /testfile.txt |
+      | permissions | 1             |
+    When user "Alice" updates the last public link share using the sharing API with
+      | permissions | 3 |
+    Then the OCS status code should be "996"
+    And the OCS status message should be "Error sending update request to public link provider: the public share needs to have a password"
+
+
+  Scenario: user tries to update a public link to edit permission with a password when enforce-password is enabled
+    Given user "Alice" has created a public link share with settings
+      | path        | /testfile.txt |
+      | permissions | 1             |
+    When user "Alice" updates the last public link share using the sharing API with
+      | permissions | 3    |
+      | password    | 1234 |
+    Then the OCS status code should be "100"
+    And the OCS status message should be "OK"
+    When the public accesses the preview of the following files from the last shared public link using the sharing API
+      | path         |
+      | /textfile.txt |
+    Then the HTTP status code of responses on all endpoints should be "404"
