No route matches using rspec controller test - ruby-on-rails

Question

I have the following routes:
config/routes.rb:
Rails.application.routes.draw do
scope module: :api do
namespace :v1 do
resources :users
end
end
end
controllers/api/v1/users_controller.rb:
module Api
module V1
class UsersController < ApplicationController
def index
...
end
end
end
end
The controller specs are under the folder spec/controllers/api/v1/.
spec/controllers/api/v1/users_controller_spec.rb:
module Api
module V1
RSpec.describe UsersController, type: :controller do
let!(:users) { create_list(:user, 10) }
describe 'GET /v1/users' do
before { get :index }
# Already tried `get '/v1/users'`, got the same error
it 'should return 10 users' do
expect(JSON.parse(response).size).to eq(10)
end
end
end
end
end
Once I run the tests I receive the following error:
ActionController::UrlGenerationError:
No route matches {:action=>"index", :controller=>"api/v1/users"}
Note that it "infers" the api part from somewhere, but my routes are like these:
v1/users
v1/users/:id
...
How can I make it work?

Answer 1

I believe this is because you are namespacing your test with Api::V1::UsersController, but your route is defined within the scope of Api. That's why your routes are not under /api
Try removing the Api module from the controller and test or changing scope module: :api to namespace :api
Alternatively, you could keep it all as-is and make the get request to your v1_users_path or whatever the corresponding path is when you run rails routes (instead of :index).
