How can I test a request with a literal given querystring?

Question

For testing a given API I have to test a request with an exact querystring, because the whole querystring is hashed together with a shared secret for security, like

inject?a=1&b[a]=2&b[b]=3&d=4&sign=76c8abec496a5e6c8a51c57e231e3a62612aeff0

I can only see a way to give parameters as a hash, which does not ensure the order (at least not if it's a nested hash):

test "right signature injects" do
  get :inject, a:1 , b: {a:2, b:3}, d: 4, sign: '76c8abec496a5e6c8a51c57e231e3a62612aeff0'
  assert_response :success
end

How can I test a get request with an exact query string?

Why does the order make a difference? If you are passing GET variables surely order doesn't matter? I can't see any reason why your test shouldn't do what you need unless there is something in the controller that responds to this request.
