+  Scenario: select_tag produces correct options
+    Given a fixture app "indexable-app"
+    And an empty file named "config.rb"
+    And a file named "source/select_tag.html.erb" with:
+    """
+    options as array: <%= select_tag :colors, options: ["red", "blue", "blorange"], include_blank: "Choose a color" %>
+    """
+    And the Server is running at "indexable-app"
+    When I go to "/select_tag.html"
+    Then I should see:
