A Quick One, While He's Away

I ran into a small problem using assert_select_email -- it expects multipart messages, and those we are sending are not.

A quick and dirty solution was to included the following ugly monkeypatch rewrite of the SelectorAssertions in our test_helper file:

module ActionController
  module Assertions
    module SelectorAssertions
      def assert_select_email(&block)
        deliveries = ActionMailer::Base.deliveries
        assert(!deliveries.empty?, "No e-mail in delivery list")
        for delivery in deliveries
          for part in delivery.parts.empty? ? [delivery] : delivery.parts.select{|p| p["Content-Type"].to_s =~ /^text\/html\W/}
            root = HTML::Document.new(part.body).root
            assert_select(root, ":root", &block)
          end
        end
      end
    end
  end
end
