Rails 3 Functional Test: assert_select finds nothing on XHR requests

gistfile1.rb

setup do
  xhr :post, :summarize
end

should "find a tag" do
  # FAILS in Rails3, SUCCEEDS in Rails2
  assert_select :span, :text => "some content"
  
  # SUCCEEDS in Rails3 & Rails2
  assert_match /\<span\>some content<\/span\>/, @response.body
end

assert_select will look at the Content-Type before actually testing. If it sees xhr/js, it will assume the response is rjs. That being said, I don't have a solution. I supposed you could extract the regexs from assert_select and write a test helper on your own?

Yeah, I'm using assert_match for now. Honestly, I don't like functional tests that expect certain tags to be in place, especially something as generic as span. I think just matching the content is sufficient.
