第 5 章 控制器测试 

 

5.1基础

rails generate rspec:controller home 

 

RSpec.describe HomeController, type: :controller do

  describe ‘#index‘ do

    it "responds successfully" do

      get :index

      expect(response).to be_success

      # response 对象包含应用返回给浏览器的所有数据，包括 HTTP 响应码。

      # be_success 检查响应的状态是成 功(200 响应)还是失败(例如 500 异常)。

      expect(response).to have_http_status "200" 

    end

  end

end

be_success匹配器 ,have_http_status()匹配器

 

 

5.2要验证身份的controller test

 

如果程序有Devise。测试的时候，需要身份验证，则使用Devise Test helpers

Devise includes some test helpers for controller and integration tests. In order to use them, you need to include the repective module in you test cases/specs. 

包含一个测试模块.

class PostsControllerTest < ActionController::TestCase
include Devise::Test::ControllerHelpers
end

class PostsTests < ActionDispatch::IntegrationTest
include Devise::Test::IntegrationHelpers
end

RSpec.configure do |config|
config.include Devise::Test::IntegrationHelpers, type: :feature

 config.include Devise::Test::ControllerHelpers, type: :controller

 config.include Devise::Test::ControllerHelpers, type: :view

end

然后就可以使用sign_in, sign_out方法了

 

redirect_to 匹配器 

以下测试都是get的测试。

ProjectsController

  #inde

    as an authenticated user

      responds successfully

      returns a 200 response

    as a guest

      returns a 302 response

 

      redirects to the sign_in page

 

  #show

 

    as an authorized user

      responds successfully

    as an unauthorized user

      redirects to the dashboard

 

5.3 测试用户输入。

HTTP GET外，还有POST, PATCH, DELETE与controller交互。
