Question

使用ServerSpec在Chef cookbook上运行集成测试时遇到了一个问题。当我今天尝试运行测试而没有进行任何更改时，我收到以下错误：

有谁知道为什么会这样？

根据评论：

require 'serverspec'
# require 'specinfra' #I've tried both with and without this

include SpecInfra::Helper::Exec
include SpecInfra::Helper::DetectOS

RSpec.configure do |c|
  if ENV['ASK_SUDO_PASSWORD']
    require 'highline/import'
    c.sudo_password = ask("Enter sudo password: ") { |q| q.echo = false }
  else
    c.sudo_password = ENV['SUDO_PASSWORD']
  end
end

该文件符合使用该应用程序的说明，之前未经过修改。

如果您正在使用serverspec 2+，则需要删除SpecInfra行并替换为set命令：

require 'serverspec'

set :backend, :exec

RSpec.configure do |c|
  c.before :all do
    c.path = '/sbin:/usr/sbin'
  end
end

# etc

Test Kitchen将尝试安装最新版本的ServerSpec。不幸的是，最近有一个主要版本的ServerSpec可能已经破坏了一些东西，所以你可能需要升级你的测试。

文件/tmp/busser/suites/serverspec/spec_helper.rb可能引用了常量SpecInfra，但是你还没有加载任何gem或Ruby文件实际定义该常量，所以常量是未定义的。

我无法在SpecInfra找到很多文档，但我想你只需要在shell中运行gem install specinfra来安装gem，然后在{}添加require 'specinfra'发生错误的文件的顶部。这是解决这些类型错误的常用方法。

我假设spec_helper.rb是你在某个时候写过的文件，它会被服务器规范复制到服务器上，但我从来没有使用过该工具，所以我没有＆＃39;我很了解它。您需要确保将gem安装/复制到运行测试的服务器，因此您可能需要将gem添加到serverspec的某个配置文件中。
