+Feature: Interacting with the REST API for custom fields
+    In order to interact with REST API for custom fields
+    As a user
+    I want to make sure the Redmine server replies with the correct response
+
+    Scenario: Listing of zero custom fields
+        Given I have a "NativeCurlClient" client
+        When I list all custom fields
+        Then the response has the status code "200"
+        And the response has the content type "application/json"
+        And the returned data has only the following properties
+            """
+            custom_fields
+            """
+        And the returned data "custom_fields" property is an array
+        And the returned data "custom_fields" property contains "0" items
