rails教程第8章测试错误
在Michael的Rails教程的第8.2.1章中，我得到了两个不同的测试错误。我刚接触过Rails，但是我已经三次检查语法错误和我能找到的其他任何东西。任何帮助都是非常感谢的。
错误消息1:错误“test_should_get_new”，Minitest::Result，0.9693643249993329 test_should_get_new#Minitest::Result (0.97 s) NameError: NameError:未定义局部变量或方法users_new_url' for #<UsersControllerTest:0x00000006e953f8> test/controllers/users_controller_test.rb:5:in块

assert_difference 'User.count', 1 do
post users_path, params: { user: { name: "Example User",
email: "user@example.com",
password: "password",
password_confirmation: "password" } }
end
follow_redirect!
assert_template 'users/show'
assert_not flash.nil?

在您的users_controller_test中，代码不知道users_new_url是什么。这可能是因为那条路不存在。您很可能不得不执行类似get new_user_path的操作，但是您可以通过键入rake routes并获得可用路由列表来查找。
下面是一个rake routes输出的示例：
users GET /users(.:format) users#index
POST /users(.:format) users#create
new_user GET /users/new(.:format) users#new
edit_user GET /users/:id/edit(.:format) users#edit
user GET /users/:id(.:format) users#show您可以通过将_path附加到名称中来引用命名路径。也就是说，users_path将映射到"users#index"控制器和方法。
rake routes还将帮助您解决第二个问题，即您没有为POST /signup定义的路由--您有一个GET /signup。
因此，您需要添加如下一行：
post '/signup', to: 'users#create'这个路径将映射到您的UsersController的#create方法，我在代码中看到了这个方法。
