Why "bad URI(is not URI?): http://www.example.com:80index"? - ruby-on-rails

Question

I'm making RSpec test.
Our website like this. It's plain website.
https://somewebsite.com/restaurant
So every time I try to test, it shows this kind of error.
$ bundle exec rspec spec/requests/restaurant_spec.rb
Restaurants
GET /index
index responds successfully (FAILED - 1)
Failures:
1) Restaurants GET /index index responds successfully
Failure/Error: get :index
URI::InvalidURIError:
bad URI(is not URI?): http://www.example.com:80index
# ./spec/requests/restaurant_spec.rb:6:in `block (3 levels) in <top (required)>'
Finished in 0.00484 seconds (files took 6.41 seconds to load)
1 example, 1 failure
My test code is this.
require 'rails_helper'
RSpec.describe "Restaurants", type: :request do
describe "GET /index" do
it "index responds successfully" do
get :index
expect(response).to be_success
end
end
end
And my application code here.
def index
#q = Restaurant.ransack(params[:q])
if params[:q].present?
#all_restaurants = #q.result(distinct: true).page(params[:page])
else
#all_restaurants = Restaurant.page(params[:page])
end
end
BTW my routing is this.
scope "(:locale)", locale: /en|ja/ do
get 'restaurant/' => 'restaurant#index'
get 'restaurant/:id' => 'restaurant#show'
end
Why this error happens? Please let me know. Thanks in advance.

I think this error is related to the describe block in RSpec. Change "Restaurants" to just Restaurant (singular and without the quotation marks).
require 'rails_helper'
RSpec.describe Restaurant, type: :request do
describe "GET /index" do
it "index responds successfully" do
get :index
expect(response).to be_success
end
end
end
Also, I think you'll have to change your routes to get this to work properly. Since you have a resourceful controller, use resource routing:
scope "(:locale)", locale: /en|ja/ do
resources :restaurants, only: %i[index show]
end
Should give you the routes /restaurants and /restaurants/:id with your desired locales, which is the Rails convention for this type of routing. And it'll also allow you to use :index and :show in your RSpec tests.
