厨师ServerSpec SpecInfra未初始化常数NameError

Question

在使用ServerSpec在我的厨师食谱上运行集成测试时，我遇到了一个问题。当我今天试图运行测试时，没有做任何更改，我得到了以下错误：

tl;dr

/tmp/busser/suites/serverspec/spec_helper.rb:3:in <top (required)>': uninitialized constant SpecInfra (NameError)

有人知道为什么会发生这种事吗？

根据评论意见：

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

该文件是按照为使用应用程序而设置的指令进行的，并且以前使用过未更改的操作。

Test将尝试安装最新版本的ServerSpec。不幸的是，最近有一个ServerSpec的主要版本，它可能破坏了一些东西，所以您可能需要升级您的测试。

参见http://lists.opscode.com/sympa/arc/chef/2014-10/msg00027.html上的线程

如果使用的是serverspec 2+，则需要删除SpecInfra行并用set命令替换：

require 'serverspec'

set :backend, :exec

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

# etc

关于kitchen.ci - https://github.com/test-kitchen/guide-started-git-cookbook/pull/3上的示例回购，我的最新公关中有更多信息。

/tmp/busser/suites/serverspec/spec_helper.rb文件可能引用常量SpecInfra，但是您还没有加载任何gem或Ruby实际定义的常量，因此该常量是未定义的。

我在SpecInfra上找不到多少文档，但我想您只需在shell中运行gem install specinfra才能安装gem，然后在发生错误的文件顶部添加require 'specinfra'。这是修复这些类型错误的通常方法。

我假设spec_helper.rb是您在某个时候编写的一个文件，它是由serverspec复制到服务器上的，但我从未使用过该工具，所以我对它不太了解。您需要确保gem被安装/复制到正在运行测试的服务器上，因此您可能需要将gem添加到serverspec的某些配置文件中。
