通过 RSpec 设置会话值

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 方法中的会话总是空的。有没有办法通过 RSpec 控制会话？

Answer 1

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

您需要将 helper methods module 添加到示例组中。假设你有一个 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

你也可以automatically include the module into all specs, or specific specs by using 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
