   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.
