+Feature: Snippets
+  In order to manage snippets
+  As an administrator
+  I want to add/edit/delete snippets of my site
+
+Background:
+  Given I have the site: "test site" set up
+  And I am an authenticated user
+  And a snippet named "yield" with the template:
+    """
+    HELLO WORLD !
+    """
+
+Scenario: Updating a Snippet that includes another snippet
+  And a page named "snippet-test" with the template:
+    """
+    {% include 'yield' %}
+    """
+  When I go to theme assets
+  And I follow "yield"
+  And I fill in "snippet_template" with "{% include 'other' %}"
+  And I press "Update"
+  Then I should see "Snippet was successfully updated."
+  And I should have "{% include 'other' %}" in the yield snippet
+  Then show me the page
