Rails functional test how to assert json result?

As title, I want to have my functional test check results from a json
render result, how can I achieve this?

   gem install assert_xpath

then in your test:

   assert_xml @response.body
   js = assert_xpath('//path-to/your/javascript').text
   assert_javascript js
   json = assert_xpath('//path-to/your/json')
   hash = assert_json(json)
   assert{ hash[:value] == 42 }

That is a long row to hoe just to get down to a 42. (You cannot unit test the result of rendering the json into a browser, either way.) So you could stop after the second line and just use:

   assert{ js =~ /value: 42/ }

hmm... works, but obviously not a good looking one... thanks a lot
anyway. I would see if I could come up with something.
