undefined local variable or method `api_v1_airlines' for #<AirlinesControllerTest:0x000000565ff5a928>

May 7, 2023

I am not sure why minitest is not recognising my route:

# airlines_controller_test.rb
class AirlinesControllerTest < ActionDispatch::IntegrationTest
    test "should get index" do
      get api_v1_airlines
      assert_response :success
    end
  end

` api_v1_airlines GET    /api/v1/airlines(.:format)                                                                        api/v1/airlines#index {:params=>:slug}

I ran the test and it gave me

`Error:
AirlinesControllerTest#test_should_get_index:
NameError: undefined local variable or method `api_v1_airlines' for #<AirlinesControllerTest:0x0000006532df84b8>
    test/controllers/airlines_controller_test.rb:5:in `block in <class:AirlinesControllerTest>'`

what am I doing wrong? It is not recognizing the route but it is defined in rails routes. What am I not including in my test file?

>Solution :

According to the docs, you should use the *_url form of the route helper.

class AirlinesControllerTest < ActionDispatch::IntegrationTest
    test "should get index" do
      get api_v1_airlines_url
      assert_response :success
    end
  end
