Rails 4 testing nested resources with multiple URL params

I have been at this for a few hours, still can't figure it out. I have 2 tests on 2 actions on a nested resources controller. requests is the parent resources route, and response is the nested resources route.

These 2 tests give me a no route matches error. Does not make sense. In the first test, it tries to run the update action instead of the edit. Here are my tests:

test "should get edit" do
  assert_routing edit_request_response_path(@myresponse.request_id, @myresponse), { :controller => "responses", :action => "edit", :request_id => @myresponse.request_id.to_s, :id => @myresponse.id.to_s }
  get :edit, params: { id: @myresponse, request_id: @myresponse.request_id }
  assert_response :success
end

test "should update response" do
  post :update, :request_id => @myresponse.request_id, response: { body: @myresponse.body, request_id: @myresponse.request_id, status: @myresponse.status, subject: @myresponse.subject, user_id: @myresponse.user_id }
  assert_redirected_to response_path(assigns(:response))
end

Here are the errors:

3) Error:
ResponsesControllerTest#test_should_get_edit:
ActionController::UrlGenerationError: No route matches {:action=>"edit", :controller=>"responses", :params=>{:id=>"980190962", :request_id=>"999788447"}}
