辅助规范中未定义路径 [英] paths are not defined in helper specs

问题描述

我刚刚将 Rails 版本从 4.2.6 升级到 5.0.0.rc1 并使用 RSpec 版本 3.5.0.beta4>.

I've just upgraded my Rails version from 4.2.6 to 5.0.0.rc1 and using RSpec version 3.5.0.beta4.

问题是；我有一个方法，它在我的助手中调用 root_path 并且路径没有在助手规范中定义.版本升级后开始出现问题.

Problem is; I have a method which calls root_path in my helper and paths are not defined in helper specs. Issue started after version upgrade.

运行辅助规范时出现以下错误；

I'm getting the following error when I run my helper spec;

NoMethodError:
       undefined method `root_path' for #<#<Class:0x00000002749080>:0x00000011f3e650>

我尝试将以下行添加到我的助手中；

I've tried to add following line to my helper;

include Rails.application.routes.url_helpers

但现在错误如下；

NameError:
       undefined local variable or method `default_url_options' for #<#<Class:0x00000001efa550>:0x0000001784ccd8>

如何为帮助程序规范或 default_url_options 定义路径帮助程序?

How can I define path helpers for helper specs or default_url_options?

推荐答案

这似乎是 RSpec 的一个错误，你可以在辅助规范中做的一件事就是自己添加必要的方法.

This seems like it may be a bug with RSpec, one thing you can do in your helper specs is add the necessary methods yourself.

describe MyHelper do
  context "doing something" do
  helper do
    include Rails.application.routes.url_helpers

    def default_url_options
      {}
    end
  end

  it "should work" do
    expect(helper.run_it).to be_truthy
  end
end
