Question

我使用Michael Hartl的教程。目前我在chapter 10。在第10.28部分，当我尝试运行测试时：

bundle exec rspec spec/requests/authentication_pages_spec.rb

我收到此错误：

Failures:

  2) Authentication authorization for non-signed-in users in the Microposts
     controller submitting to the destroy action Failure/Error: before { delete

这是我的authentication_pages_spec.rb：

我尝试使用Micheal Hart'github更正我的代码，但没有结果。有人知道吗？

在你的测试中，你写下这个：

before { delete microposts_path(FactoryGirl.create(:micropost)) }

这将告诉测试框架对您路线中DELETE创建的路径生成microposts_path请求。

您的rake routes输出具有以下内容：

   microposts POST   /microposts(.:format)        microposts#create
    micropost DELETE /microposts/:id(.:format)    microposts#destroy

查看上面的microposts vs micropost。您应该在测试中使用micropost_path。
