如何在Rails测试用例中发送不明确的请求？

Question

I have the following definitions in my routes:

resources :demands { resources: :solutions }
resources :technologies { resources: :solutions }

and in my controller test, I want to send two requests:

Get /demands/d123/solutions?technology_id=t123
Get /technologies/t123/solutions?demand_id=d123

But they both match the same invokes(in SolutionsControllerTest):

get :index, demand_id: d123, technology_id: t123

it match the first definition in routes.rb, which is

resources :demands { resources: :solutions }

How should I send both requests in distinct methods?

Answer 1

Functional (Controller) tests fake the whole request stage. Instead of invoking a rails server and sending an actual request ActionController::TestCase just creates a Request object and passes it to a controller instance. This lets you poke around in way which is not possible in an integration test due to the server and test running in separate processes.

Instead you would want to use a integration test and actually send a HTTP request so that it goes through the routing component:

require 'test_helper'

class AmbiguousRoutesTest < ActionDispatch::IntegrationTest
  test "is /demands/d123/solutions?technology_id=t123 ambigous?" do
     get "/demands/d123/solutions?technology_id=t123"
     # @todo write assertions about the response
  end 
end
