UrlGenerationError when running RSpec Test

I am trying to run a test that makes sure my template is show

displayed in a restaurant. After running the test, I get:

 1) RestaurantsController GET #show 
     Failure/Error: before { get :show }
     ActionController::UrlGenerationError:
       No route matches {:action=>"show", :controller=>"restaurants"}

      

        
        
        
      

    

Not sure why his saying when there really is a route for showing restaurants:

    restaurants GET    /restaurants(.:format)          restaurants#index
                POST   /restaurants(.:format)          restaurants#create
 new_restaurant GET    /restaurants/new(.:format)      restaurants#new
edit_restaurant GET    /restaurants/:id/edit(.:format) restaurants#edit
     restaurant GET    /restaurants/:id(.:format)      restaurants#show
                PATCH  /restaurants/:id(.:format)      restaurants#update
                PUT    /restaurants/:id(.:format)      restaurants#update
                DELETE /restaurants/:id(.:format)      restaurants#destroy

      

        
        
        
      

    

Test

require "rails_helper"

describe RestaurantsController do
  describe "GET #show" do
    before { get :show }

    it { should render_template("show") }
  end
end
