我是厨师规范的新手，并试图弄清楚如何在我的食谱中使用单元测试。我已经安装了 chefdk（在不同的 ubuntu 实例上的 v2 和 v3）和刀规格插件。创建“apache_wrapper”食谱后，我更改了下一个文件：

规范/spec_helper.rb

require 'chefspec'
require 'chefspec/berkshelf'

RSpec.configure do |config|
config.log_level = :debug
  config.platform = 'ubuntu'
  config.version = '12.04'
end

规范/食谱/default_spec.rb

require_relative '../spec_helper'

describe 'apache_wrapper::default' do
  subject { ChefSpec::Runner.new.converge(described_recipe) }

  it 'includes community cookbook apache2' do
    expect(subject).to include_recipe('apache2')
  end

  it 'creates a template with attributes' do
    expect(subject).to create_template('/var/www/html/index.html').with(
      user:   'root',
      group:  'root',
      backup: true,
    )

    expect(subject).to_not create_template('/var/www/html/index.html').with(
      user:   'bacon',
      group:  'fat',
      backup: true,
    )
  end
end

在我的食谱 default.eb 中：

include_recipe 'apache2'

template "/var/www/html/index.html" do
  source "index.html.erb"
  mode 00644
end

但是当我调用 rspec 时，我得到了下一个：

$ pwd
/tmp/apache_wrapper
$ rspec
...
Failures:

  1) apache_wrapper::default includes community cookbook apache2
     Failure/Error: subject { ChefSpec::Runner.new.converge(described_recipe) }
     Chef::Exceptions::CookbookNotFound:
       Cookbook apache_wrapper not found. If you're loading apache_wrapper from another cookbook, make sure you configure the dependency in your metadata
     # ./spec/recipes/default_spec.rb:24:in `block (2 levels) in <top (required)>'
     # ./spec/recipes/default_spec.rb:27:in `block (2 levels) in <top (required)>'

  2) apache_wrapper::default creates a template with attributes
     Failure/Error: subject { ChefSpec::Runner.new.converge(described_recipe) }
     Chef::Exceptions::CookbookNotFound:
       Cookbook apache_wrapper not found. If you're loading apache_wrapper from another cookbook, make sure you configure the dependency in your metadata

     # ./spec/recipes/default_spec.rb:31:in `block (2 levels) in <top (required)>'

Finished in 0.32355 seconds (files took 2.39 seconds to load)
2 examples, 2 failures

Failed examples:

rspec ./spec/recipes/default_spec.rb:26 # apache_wrapper::default includes community cookbook apache2
rspec ./spec/recipes/default_spec.rb:30 # apache_wrapper::default creates a template with attributes

并在食谱文件夹 Berksfile.lock 出现。谁能告诉我我做错了什么？

升级版：

伯克斯文件： 

source "https://supermarket.getchef.com"
cookbook 'apache2', '= 1.9.6'

Berksfile.lock

DEPENDENCIES
  apache2 (= 1.9.6)

GRAPH
  apache2 (1.9.6)
    iptables (>= 0.0.0)
    logrotate (>= 0.0.0)
    pacman (>= 0.0.0)
  iptables (0.14.0)
  logrotate (1.7.0)
  pacman (1.1.1)

UPD2：

cat ../apache_wrapper/metadata.rb | grep -E 'dep|nam'
name             'apache_wrapper'
depends 'apache2'

UPD3：

我也尝试使用下一个

let (:chef_run) { ChefSpec::ServerRunner.new.converge 'apache_wrapper::default' }

现在收到

Missing Cookbooks:
------------------
No such cookbook: apache_wrapper

Expanded Run List:
------------------
* apache_wrapper::default

F

Failures:

  1) apache_wrapper::default includes community cookbook apache2
     Failure/Error: let (:chef_run) { ChefSpec::ServerRunner.new.converge 'apache_wrapper::default' }
     Net::HTTPServerException:
       412 "Precondition Failed "
     # ./spec/default_spec.rb:23:in `block (2 levels) in <top (required)>'
     # ./spec/default_spec.rb:26:in `block (2 levels) in <top (required)>

我不明白，我做错了什么，今天我开始了新的实例，在那里安装了 ruby​​2.1 和所有的 gem，比如 chefspec 和其他。现在使用 rake 运行测试，但仍然得到同样的错误

解决方案：只需将“元数据”添加到食谱 Berksfile

您必须在您的食谱中指定“apache2”作为依赖项metadata.rb：

name             'COOKBOOK NAME'
maintainer       'YOUR NAME'
maintainer_email 'YOUR_EMAIL'
...

version          '0.0.1'

depends          'apache2'

之后，您可以在您的食谱中包含来自“apache2”的食谱。

更新：

您还需要指定“apache_wrapper”食谱的位置，请查看 chefspec 的配置选项以获取更多信息

添加metadata到您的 Berksfile 文件中，Berkshelf 会将您的本地食谱添加到本地食谱列表中。

来自 berkshelf.com：

metadata 关键字就像在 Bundler 的 Gemfile 中说 gemspec。它说，“在我的 Berksfile 的相同相对路径中有一个 metadata.rb 文件”。这允许您解决当前正在处理的 Cookbook 的依赖项，就像您解决当前正在使用 Bundler 处理的 Gem 的依赖项一样。
