+Feature: conversions
+	Background:
+		Given using api version "1"
+    Given using new dav path
+    Given user "user0" exists
+
+  Scenario: Converting a file works
+    Given user "user0" uploads file "data/clouds.jpg" to "/clouds.jpg"
+    Then as "user0" the file "/clouds.jpg" exists
+    When user "user0" converts file "/clouds.jpg" to "image/png"
+    Then the HTTP status code should be "200"
+    Then the OCS status code should be "200"
+    Then as "user0" the file "/clouds.png" exists
