+Feature: Test the database server resource
+  As an administrator
+  I want to make sure the database service is deployed successfully
+  In order to be available for other services later
+
+  Background:
+    Given the chef role "database-server" exists on admin node
+    And the "database" cookbook exists on the admin node
+
+  @postgresql
+  Scenario: Database barclamp is deployed using PostgreSQL as backend
+    Given the "postgresql" cookbook exists on the admin node
+    And the barclamp proposal is using "postgresql" as sql engine
+    When the node with database role has been detected successfully
+    Then I can establish connection to "postgresql" database server
+    And I can create a database called "cucumber_test"
+    And I can drop the database "cucumber_test" successfully
