How can I assert my Ajax request and test the JSON output from Ruby on Rails functional tests?

Answer

Rails has JSON support built in:

def json_response
    ActiveSupport::JSON.decode @response.body
end

No need for a plugin

Then you can do something like this:

assert_equal "Mike", json_response['name']
