Question

我目前正在使用RSpec来测试我的Rails 4应用程序，在测试时，我发现了这个奇怪的问题：subject.current_user在上下文中的第二个方法中为nil。代码段：

  describe 'GET #register_as_team:' do
    context 'user logged in but not admin:' do
      login_user
      it 'should redirect_to user_path if user is not student' do
        get :register_as_team, id: subject.current_user.id
        expect(response).to redirect_to(user_path(subject.current_user))
        expect(flash[:danger]).not_to be_nil
      end

      it 'should redirect_to student_path if user is a non-pending student' do
        student = FactoryGirl.create(:student, user: subject.current_user, is_pending: false)
        get :register_as_team, id: subject.current_user.id
        expect(response).to redirect_to(student_path(student))
      end
    end
  end

因此，当第一次使用subject.current_user时，它就可以了，我可以获取已记录的用户，但在第二种方法中它返回nil。

有关背景信息，login_user是这样的：

module ControllerMacros
  def login_user(user = nil)
    before(:each) do
      # @request.env["devise.mapping"] = Devise.mappings[:user]
      user ||= User.find_by(email: 'default_user@controller.spec')
      user ||= FactoryGirl.create(:user, email: 'default_user@controller.spec', uid: 'default_user.controller.spec')
      sign_in user
    end
  end
end

在示例中，subject只能是resolved once 当您执行get :register_as_team, id: subject.current_user.id时，您基本上已经解决了subject并且subject.current_user未在下一行得到解决。

试试这个：

  describe 'GET #register_as_team:' do
    context 'user logged in but not admin:' do
      login_user
      it 'should redirect_to user_path if user is not student' do
        user = subject.current_user
        get :register_as_team, id: user.id
        expect(response).to redirect_to(user_path(user))
        expect(flash[:danger]).not_to be_nil
      end

  it 'should redirect_to student_path if user is a non-pending student' do
    student = FactoryGirl.create(:student, user: subject.current_user, is_pending: false)
    user = subject.current_user
    get :register_as_team, id: user.id
    expect(response).to redirect_to(student_path(student))
  end
end

RSpec with Devise：subject.current_user在上下文中的第二个方法中使用时为nil
