ruby - 升级到 Rails 4，我无法通过在 Rails 3 中通过的设计测试

Question

未定义的局部变量或方法“login_user”

为什么我的 Controller 没有得到扩展的 ControllerMacros ???

在 rspec-rails 3 中，规范不再根据路径自动设置其类型，因此您的 Controller 规范不再具有类型 :controller。您可以:

• 使用 config.infer_spec_type_from_file_location! 选项可以重新启用它
• 使用 type: :controller 明确标记您的 Controller 规范
