未定义的局部变量或方法 - 使用 Beaker 测试 Puppet 模块 [英] Undefined local variable or Method - Testing Puppet Modules using Beaker

问题描述

我对这一切都很陌生.我正在尝试使用 Beaker 测试木偶模块.我一直收到这个:

I'm quite new to all of this. I am trying to test out a puppet module using Beaker. I keep getting this:

 NoMethodError: undefined method `describe' for 
 #Beaker::TestCase:0x007fd6f95e6460
 /Users/user1/beaker/Puppet/puppet-files/spec/classes/unit_spec.rb:3  
 /Users/user1/.rvm/gems/ruby-2.2.7/gems/beaker-3.24.0/bin/beaker:9  
 /Users/user1/.rvm/gems/ruby-2.2.7/bin/ruby_executable_hooks:15  
 /Users/user1/.rvm/gems/ruby-2.2.7/bin/ruby_executable_hooks:15.
 This is the command that I'm running - "beaker --hosts myhost.yaml --pre-suite spec".

我的 unit_spec.rb 包含这个:

My unit_spec.rb contains this:

  require 'puppetlabs_spec_helper/rake_tasks'

  describe 'application' do
  context 'applied to supported operating system' do
  on_supported_os.each do |os, facts|
  context "#{os}" do
   let(:facts) do
     facts
   end

   context "without any parameters" do
     let(:params) {{ }}

     it { is_expected.to compile.with_all_deps }
     it { is_expected.to contain_class('files') }
     end
    end
   end
  end


    context 'applied to unsupported operating system' do
    describe 'ubuntu-14-x86_64' do
    let(:facts) {{
     :osfamily        => 'Debian',
     :operatingsystem => 'Ubuntu'
      }}

    it { is_expected.to raise_error(Puppet::Error, /Ubuntu not supported/) }
    end
   end
  end

任何帮助将不胜感激！顺便说一句，我正在使用 'puppetlabs_spec_helper/rake_tasks'，因为当我刚刚使用 'spec_helper' 时，它给了我一个错误，即使它在那里也无法加载此类文件".

Any help would be much appreciated! Btw, I am using 'puppetlabs_spec_helper/rake_tasks' due to the fact that when I just used 'spec_helper' it gave me an error that it could not "load such file" even though it was there.

另外，我也尝试过

RSpec.Describe

这也没有解决问题.我收到以下错误 -

That did not fix the issue either. I get the following error -

 NameError: undefined local variable or method `on_supported_os' for #Class:0x007f92a61d5e58

我意识到这可能是 RSpec Puppet 的问题，因为该模块之前已通过 Puppet RSpec 进行过测试，但是现在我正在尝试使用 Beaker 进行测试，但不太确定如何完全实现！

I realise that this might be an RSpec Puppet issue, as this module was previously tested through puppet RSpec, however now I am trying to test using Beaker and not quite sure how to fully achieve that!

推荐答案

您正在混淆基于单元和基于 VM 的测试.

You're mixing up unit- and VM-based testing.

• rspec-puppet(和 rspec-puppet-facts' on_supported_os) 用于基于目录的单元测试.它们不需要虚拟机，可以为您提供有关模块语法和逻辑的快速反馈.

• rspec-puppet (and rspec-puppet-facts' on_supported_os) are for catalog-based unit testing. They do not require a VM, and can give you quick feedback on syntax, and logic of your module.

beaker，以及推荐的 beaker-rspec 附加组件，提供完整的端到端测试功能，使用实际的虚拟机，并测试完整的堆栈部署(定义在你测试).

beaker, and the recommended beaker-rspec add-on, provide full end-to-end testing capabilities, using actual VMs, and testing a complete stack deploy (as defined in you tests).

现有模块的主要入口点通常是 rake.使用 rake -T 查看模块中现有的 rake 任务.在一个编写良好的模块中，它应该有 rspec-puppet(通常称为 spec)和 beaker(通常称为 beaker 或 acceptance)的任务>).

The main entry point for existing modules is usually rake. Take a look at the existing rake tasks in the module using rake -T. In a well-written module it should have tasks for both rspec-puppet (usually called spec), and beaker (often called beaker, or acceptance).

如果它是您自己的模块，您可能还想查看新的 Puppet 开发工具包，在单个安装程序中获取最重要的工具.

If it is your own module, you also might want to look into the new Puppet Development Kit to get the most important tools in a single installer.
