Question

我再次出现错误，一切都在localhost中完美运行，但是当我运行＆＃34;捆绑exec rake test＆＃34;时，我有一个错误。

错误

$ bundle exec rake test
 1) Error:

Answer 1

您的current_user方法返回nil，因为您的终端的值为session[:user_id]和cookies.signed[:user_id]，因此if condition都没有通过。尝试else并为current_user提供一些价值。或者您也可以使用pry之类的调试工具来检查current_user方法中季节和Cookie的值。

网站运行正常，但是当我运行“捆绑执行rake test”时，我发现了一个错误-2
