如何編寫路由規格測試 - 軌道4

Question

我試圖寫一個測試SessionsController，我寫道：

我使用規格3.3

RSpec.describe SessionsController, type: :controller do 

     describe SessionsController do 

      describe "POST create" do 

       it "sign in should have a valid route" do 
        post('/api/signin').should route_to('api/sessions#create') 
       end 

      end 

     end 

    end 

這個程序是主要是作爲一個API工作，所以現在不需要意見。

在我的路線，我有以下：

match  '/api/signin',       to: 'api/sessions#create', 

然而，測試未通過。

有什麼建議嗎？

編輯：錯誤：

rspec ./spec/controllers/sessions_controller_spec.rb:27 # SessionsController SessionsController POST create sign in should have a valid route 
rspec ./spec/controllers/sessions_controller_spec.rb:31 # SessionsController SessionsController POST create creates a new session 

EDIT2：增加了完整的測試代碼

Answer 1

必須指定type: :routing和使用assert_routing它有封地來測試2種方式的路線（路線代和路由匹配）

我把我的答案作爲一般，所以其他人可以從中獲取信息，請適應你的情況

describe MyController, type: :routing do 
    it 'routing' do 
    # This is optional, but also a good reminder to tell me when I add a route 
    # and forgot to update my specs. 
    # Please see bellow for the helper definition 
    expect(number_of_routes_for('my_controller')).to eq(8) 

    # Then test for the routes, one by one 
    assert_routing({method: :get, path: '/my_controller'}, {controller: 'my_controller', action: 'index'}) 
    assert_routing({method: :get, path: '/my_controller/1'}, {controller: 'my_controller', action: 'show', id: '1'}) 
    # ... And so on, for each route 
    end 
end 

注意：如果有assert_routing出現錯誤（我猜它會隨着match的情況下，但我不記得了），然後看看assert_generates和assert_recognizes

而且number_of_routes_for幫手

def number_of_routes_for(controller) 
    Rails.application.routes.routes.to_a.select{ |r| r.defaults[:controller] == controller }.count 
end
