ruby-on-rails - 通过 RSpec 设置 session 值

Question

我当前的代码如下所示:

/spec/support/spec_test_helper.rb

module SpecTestHelper
  def login_admin
    user = FactoryGirl.create(:user, type: 0)
    session[:user_id] = user.id
  end
end

/app/controllers/application_controller.rb

def current_user
  if session[:user_id].nil?
    render plain: 'Error', status: :unauthorized
  else
    @current_user ||= User.find(session[:user_id])
  end
end

不幸的是，current_user方法中的session总是空的。有没有办法通过 RSpec 控制 session ？

Answer 1

这将根据规范类型而变化。例如，feature 规范不允许您直接修改 session 。但是，controller 规范会。

您需要包含 helper methods module进入您的示例组。假设您有一个 WidgetsController:

require 'support/spec_test_helper'

RSpec.describe WidgetsController, type: :controller do
  include SpecTestHelper

  context "when not logged in" do
    it "the request is unauthorized" do
      get :index
      expect(response).to have_http_status(:unauthorized)
    end
  end

  context "when logged in" do
    before do
      login_admin
    end

    it "lists the user's widgets" do
      # ...
    end
  end
end

您也可以automatically include the module进入所有规范，或specific specs通过使用 metadata .

我经常通过将配置更改添加到定义辅助方法的文件中来做到这一点:

/spec/support/spec_test_helper.rb

module SpecTestHelper
  def login_admin
    user = FactoryGirl.create(:user, type: 0)
    session[:user_id] = user.id
  end
end

RSpec.configure do |config|
  config.include SpecTestHelper, type: :controller
end
