我正在尝试测试我的 puppet 模块，但我收到一条错误消息，指出它找不到类。

我写了几个内部使用的 Puppet 模块；既然我对木偶有兴趣，我想编写测试。由于我遇到了问题，我决定从根本上重新开始一个新的干净模块来弄清楚我需要做什么。

$puppet module generate wet-splunk
<<snip interactive questions>>
$cd splunk
$rake spec
<path snip>ruby -I/Users/wet/.rbenv/versions/1.9.3-p0/lib/ruby/gems/1.9.1/gems/rspec-support-3.4.1/lib:/Users/wet/.rbenv/versions/1.9.3-p0/lib/ruby/gems/1.9.1/gems/rspec-core-3.4.1/lib /Users/wet/.rbenv/versions/1.9.3-p0/lib/ruby/gems/1.9.1/gems/rspec-core-3.4.1/exe/rspec --pattern spec/\{classes,defines,unit,functions,hosts,integration,types\}/\*\*/\*_spec.rb --color

检查文件虽然我认为它们包含它们应该包含的内容：

清单/init.pp

# <snip documentation boilterplate>
class splunk {    
}

规范/类/init_spec.rb

require 'spec_helper'
describe 'splunk' do

  context 'with defaults for all parameters' do
    it { should contain_class('splunk') }
  end
end

Could not find class ::splunk这是让我感到困惑的部分。

我阅读规范文件的方式是它在 init 中查找class{'splunk': ... }这可能是我误读了它，因为它们会以损坏的规范文件开始，但以防万一我尝试测试包。

清单/init.pp

class splunk {
  package{'splunk':
    ensure => 'present',
  }
}

规范/类/init_spec.rb 

require 'spec_helper'
describe 'splunk' do

  context 'with defaults for all parameters' do
    it { should contain_package('splunk') }
  end
end

我仍然收到类似的错误消息：

$ rake spec

很抱歉提出这样一个基本问题；我真的很感谢你的帮助。我真的很喜欢关于测试 Puppet 代码的优秀教程的链接；我很想使用 Vagrant 来确保我的代码实际上会按照我的意愿去做。

更新： 我相信我遵循了@Peter_Souter 的建议；我仍然收到找不到课程的错误。我发布了引用的文件的内容，以尝试验证我做了正确的事情，以防出现其他错误。

$ cat .fixtures.yml 
fixtures:
  symlinks:
    "splunk": "#{source_dir}"
$ cat spec_helper.rb 
require 'puppetlabs_spec_helper/module_spec_helper'
$ cat Rakefile 
require 'puppetlabs_spec_helper/rake_tasks'
require 'puppet-lint/tasks/puppet-lint'
PuppetLint.configuration.send('disable_80chars')
PuppetLint.configuration.ignore_paths = ["spec/**/*.pp", "pkg/**/*.pp"]

desc "Validate manifests, templates, and ruby files"
task :validate do
  Dir['manifests/**/*.pp'].each do |manifest|
    sh "puppet parser validate --noop #{manifest}"
  end
  Dir['spec/**/*.rb','lib/**/*.rb'].each do |ruby_file|
    sh "ruby -c #{ruby_file}" unless ruby_file =~ /spec\/fixtures/
  end
  Dir['templates/**/*.erb'].each do |template|
    sh "erb -P -x -T '-' #{template} | ruby -c"
  end
end
$ cat Gemfile
source 'https://rubygems.org'

puppetversion = ENV.key?('PUPPET_VERSION') ? "#{ENV['PUPPET_VERSION']}" : ['>= 3.3']
gem 'puppet', puppetversion
gem 'puppetlabs_spec_helper', '>= 0.8.2'
gem 'puppet-lint', '>= 1.0.0'
gem 'facter', '>= 1.7.0'

gem 'rspec-puppet', '~> 2.1',  :require => false
gem 'rspec-core', '3.1.7',     :require => false

rspec-puppet 模拟目录以进行测试的方式，它创建一个带有所需模块的 fixtures 目录。所以现在它在一个空目录上运行它，所以它找不到你的模块。我们通常使用 puppetlabs-spec-helper 来解决这个问题，它会在该固定装置目录中创建一个指向您当前存储库的 simlink。

我建议将以下内容添加到您的文件中：

# .fixtures.yml 
fixtures:
  symlinks:
    "splunk": "#{source_dir}"

# spec_helper.rb
require 'puppetlabs_spec_helper/module_spec_helper'

# Rakefile
require 'puppetlabs_spec_helper/rake_tasks'

# Gemfile
gem 'rspec-puppet', '~> 2.1',  :require => false
gem 'rspec-core', '3.1.7',     :require => false

你能试试，然后告诉我它是否适合你吗？

如果有人像我一样偶然发现这个线程。对我来说正确答案如下：

为什么我会得到 puppet-rspec 'class does not exist'？

意味着你必须这样做：

puppet module generate foo-bar

然后解决这个问题

bundle exec rspec-puppet-init

这不是很好，但比处理隐藏的点文件更好。
