+Feature: form_tag helper
+
+  Scenario: form_tag produces relative links
+    Given a fixture app "indexable-app"
+    And an empty file named "config.rb"
+    And a file named "source/form_tag.html.erb" with:
+    """
+    absolute: <% form_tag "/needs_index.html#absolute", :relative => true do %>
+    <% end %>
+    relative: <% form_tag "needs_index.html#relative", :relative => true do %>
+    <% end %>
+    """
+    And a file named "source/form_tag/sub.html.erb" with:
+    """
+    absolute: <% form_tag "/needs_index.html#absolute", :relative => true do %>
+    <% end %>
+    relative: <% form_tag "../needs_index.html#relative", :relative => true do %>
+    <% end %>
+    """
+    And the Server is running at "indexable-app"
+    When I go to "/form_tag.html"
+    Then I should see 'action="needs_index.html#absolute"'
+    Then I should see 'action="needs_index.html#relative"'
+    When I go to "/form_tag/sub.html"
