Question

我试图测试我的木偶模块，但是我收到一条错误消息，表示它无法找到课程。

我写了几个内部使用的Puppet模块;既然我对傀儡有所了解，我想写测试。由于我遇到了问题，我决定从一个新的清洁模块开始，找出我需要做的事情。

$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了应有的内容：

表现/ init.pp

# <snip documentation boilterplate>
class splunk {    
}

规格/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让我感到困惑。

我读取spec文件的方式是查看class{'splunk': ... }的init内部。这可能是我误读了它，因为看起来很奇怪他们会从破坏的spec文件开始，但以防万一我尝试测试包而不是

表现/ init.pp

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

spec / classes / 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;我非常感谢你的帮助。我非常喜欢链接到测试Puppet代码的好教程;我喜欢使用Vagrant来确信我的代码实际上会按照我的意愿行事。

更新我相信我已经关注了@ Peter_Souter的建议;我仍然得到它无法找到课程的错误。我发布了引用的文件的内容以尝试和验证我做了正确的事情，以防万一有其他错误。

$ 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

Answer 1

rspec-puppet模拟目录进行测试的方式，它会生成一个包含所需模块的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解决这个问题，它会在当前的fixtures目录中创建一个simlink链接。

我建议在文件中添加以下内容：

# .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

你能试试并告诉我它是否适合你？

Answer 2

如果有人像我一样偶然发现这个话题。对我来说，正确的答案在：

Why do I get puppet-rspec 'class does not exist' when it does?

意味着你必须这样做：

puppet module generate foo-bar

然后解决此问题

bundle exec rspec-puppet-init

这不是很好，但更好的是处理隐藏的点文件。

Puppet：rake spec找不到class :: splunk
