+Feature: Article tags
+  In order to organize the information
+  As an editor
+  I want to tag the articles

+  Scenario: Assign tags to an article

+    And I click on 'New Article'
+    And I fill the new article form with valid data
+    And I tag the article with "foo, bar"
+    When I click on 'Create'
+    Then I should be redirected to the new article show page
+    And I should see the newly created article
+    And I should see the tags
