rspec - ChefSpec 测试出现 "Cookbook not found"错误

Question

我正在尝试运行我的 ChefSpec 测试。

这是我的 ChefSpec 测试:

require_relative '../spec_helper'

describe 'my-demo::basesystem' do

  let(:chef_run) { ChefSpec::Runner.new.converge(described_recipe)}

  describe 'basesystem' do

    it "should be installed" do
      expect(chef_run).to install_package('build-essential')
    end
  end
end

这是我的食谱

include_recipe 'build-essential::default'

这是我执行 ChefSpec 测试时的错误输出

我不知道是什么问题，我认为 Berkshelf 可以解决食谱依赖项。

如果您查看堆栈跟踪:

20:  begin
21>>   include_recipe "build-essential::#{node['platform_family']}"
22:  rescue Chef::Exceptions::RecipeNotFound
23:    Chef::Log.warn "A build-essential recipe does not exist for the platform_family: #{node['platform_family']}"
24:  end

您会在第 21 行看到 build-essential cookbook 正在尝试加载与当前节点的平台系列相对应的配方。但是，对于 ChefSpec，除非您明确告诉 ChefSpec 要模拟哪种节点，否则不会设置该数据。换句话说，node['platform_family'] 是 nil，因此它试图包含一个名为 build-essential::(nothing) 的配方，这是无效的。

要解决此问题，您可以设置 platform_family 的值:

let(chef_run) do
  ChefSpec::Runner.new do |node|
    node.automatic['platform_family'] = 'ubuntu'
  end.converge(described_recipe)
end

或者(首选)，您可以告诉 ChefSpec 模拟一个节点:

let(:chef_run) { ChefSpec::Runner.new(platform: 'ubuntu', version: '12.04').converge(described_recipe) }
