会话助手测试失败

Question

来自 Michael Hartl 的书，我有以下会话助手测试：

require 'test_helper'

class SessionsHelperTest < ActionView::TestCase

 def setup
   @user = users(:michael)
   remember(@user)
 end

 test "current_user returns right user when session is nil" do
  assert_equal @user, current_user
  assert is_logged_in?
 end


 test "current_user returns nil when remember digest is wrong" do
  @user.update_attribute(:remember_digest, User.digest(User.new_token))
  assert_nil current_user
 end
end

我将当前用户定义如下

def current_user
  if (user_id = session[:user_id])
    @current_user ||= User.find_by(id: user_id)
  elsif (user_id = cookies.signed[:user_id])
    user = User.find_by(id: user_id)
    if user && user.authenticated?(cookies[:remember_token])
      log_in user
      @current_user = user
    end
  end
end

然而，当运行这个测试时我得到以下错误：

SessionsHelperTest#test_current_user_returns_right_user_when_session_is_nil           [/Users/Sites/sample_app/sample_app/test/helpers/sessions_helper_test.rb:11]:

知道如何解决这个问题吗？

我遇到了同样的问题。我的问题是我操纵了一些助手、用户模型和会话控制器。如果您仔细检查，它也可能会解决您的问题。
