用于编辑的 Rails Rspec 测试用例

问题描述

你好，我是 Rails 新手

我正在编写使用 rspec gem 的测试用例

在我的控制器中，我有编辑功能。我之前有编辑功能的动作 这是我的控制器

before_action :authorize_user,only: %i[edit update destroy]
def edit
end

**private**

  def authorize_user
    id = Question.find(params[:id]).user_id
    redirect_to root_path if id != current_user.id
  end

这是我的 rspec/requests/question_rspec.rb

  describe "GET /edit" do
    before do
      sign_in(create(:user)) # Factory Bot user
    end
    it "render a successful response" do
      question = create(:question) #Factory bot question
      # question.user = current_user
      question.save
      get edit_question_url(question)
      expect(response).to be_successful
    end

  end

我收到类似的错误

Failure/Error: expect(response).to be_successful
       expected `#<Actiondispatch::TestResponse:0x00005652448f4c50 @mon_data=#<Monitor:0x00005652448f4c00>,@mon_data_...,@method=nil,@request_method=nil,@remote_ip=nil,@original_fullpath=nil,@fullpath=nil,@ip=nil>>.successful?` to be truthy,got false
     # ./spec/requests/questions_spec.rb:105:in `block (3 levels) in <main>'

谁能告诉我

解决方法

我认为与您注释的代码有关。

很可能，这句话 id != current_user.id 是正确的。因此，要解决此问题，您需要将创建的用户设置为问题以避免在您的 authorize_user 回调中被重定向。

这里有一些测试用例更改：

  describe "GET /edit" do
    let!(:user) { create(:user) }

    before do
      sign_in(user) # Factory Bot user
    end

    it "render a successful response" do
      question = create(:question,user: user) #Factory bot question
      # question.save # you don't need it because the create operation already saves it
      get edit_question_url(question)
      expect(response).to be_successful
    end
  end
