-    # Adds the +assert_select+ method for use in Rails functional
-    # test cases, which can be used to make assertions on the response HTML of a controller
-    # action. You can also call +assert_select+ within another +assert_select+ to
-    # make assertions on elements selected by the enclosing assertion.
-    #
-    # Use +css_select+ to select elements without making an assertions, either
-    # from the response HTML or elements selected by the enclosing assertion.
-    #
-    # In addition to HTML responses, you can make the following assertions:
-    #
-    # * +assert_select_encoded+ - Assertions on HTML encoded inside XML, for example for dealing with feed item descriptions.
-    # * +assert_select_email+ - Assertions on the HTML body of an e-mail.
-    module SelectorAssertions
-      # Select and return all matching elements.
-      #
-      # If called with a single argument, uses that argument as a selector
-      # to match all elements of the current page. Returns an empty
-      # Nokogiri::XML::NodeSet if no match is found.
-      #
-      # If called with two arguments, uses the first argument as the root
-      # element and the second argument as the selector. Attempts to match the
-      # root element and any of its children.
-      # Returns an empty Nokogiri::XML::NodeSet if no match is found.
-      #
-      # The selector may be a CSS selector expression (String).
-      #
-      #   # Selects all div tags
-      #   divs = css_select("div")
-      #
-      #   # Selects all paragraph tags and does something interesting
-      #   pars = css_select("p")
-      #   pars.each do |par|

-      # An assertion that selects elements and makes one or more equality tests.
-      #
-      # If the first argument is an element, selects all matching elements
-      # starting from (and including) that element and all its children in
-      # depth-first order.
-      #
-      # If no element is specified, calling +assert_select+ selects from the
-      # response HTML unless +assert_select+ is called from within an +assert_select+ block.
-      #
-      # When called with a block +assert_select+ passes an array of selected elements
-      # to the block. Calling +assert_select+ from the block, with no element specified,
-      # runs the assertion on the complete set of elements selected by the enclosing assertion.
-      # Alternatively the array may be iterated through so that +assert_select+ can be called
-      # separately for each element.
-      #
-      #
-      # ==== Example
-      # If the response contains two ordered lists, each with four list elements then:
-      #   assert_select "ol" do |elements|
-      #     elements.each do |element|
-      #       assert_select element, "li", 4
-      #     end
-      #   end
-      #
-      # will pass, as will:
-      #   assert_select "ol" do
-      #     assert_select "li", 8
-      #   end
-      #
-      # The selector may be a CSS selector expression (String) or an expression
-      # with substitution values (Array).
-      # Substitution uses a custom pseudo class match. Pass in whatever attribute you want to match (enclosed in quotes) and a ? for the substitution.
-      #
-      # assert_select "div:match('id', ?)", /\d+/
-      #
-      # === Equality Tests
-      #
-      # The equality test may be one of the following:
-      # * <tt>true</tt> - Assertion is true if at least one element selected.
-      # * <tt>false</tt> - Assertion is true if no element selected.
-      # * <tt>String/Regexp</tt> - Assertion is true if the text value of at least
-      #   one element matches the string or regular expression.
-      # * <tt>Integer</tt> - Assertion is true if exactly that number of
-      #   elements are selected.
-      # * <tt>Range</tt> - Assertion is true if the number of selected
-      #   elements fit the range.
-      # If no equality test specified, the assertion is true if at least one
-      # element selected.
-      #
-      # To perform more than one equality tests, use a hash with the following keys:
-      # * <tt>:text</tt> - Narrow the selection to elements that have this text
-      #   value (string or regexp).
-      # * <tt>:html</tt> - Narrow the selection to elements that have this HTML
-      #   content (string or regexp).
-      # * <tt>:count</tt> - Assertion is true if the number of selected elements
-      #   is equal to this value.
-      # * <tt>:minimum</tt> - Assertion is true if the number of selected
-      #   elements is at least this value.
-      # * <tt>:maximum</tt> - Assertion is true if the number of selected
-      #   elements is at most this value.
-      #
-      # If the method is called with a block, once all equality tests are
-      # evaluated the block is called with an array of all matched elements.
-      #
-      #   # At least one form element
