ChefSpec測試「Cookbook not found」錯誤

Question

我正在嘗試運行我的ChefSpec測試。

這是我ChefSpec測試：

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 

而且這是我的食譜

include_recipe 'build-essential::default' 

這是錯誤輸出，當我執行我的ChefSpec測試

我不知道是什麼問題，我認爲Berkshelf可以解決cookbooks的依賴關係。

如果你看一下堆棧跟蹤：

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 

你會在第21行的是，建立必要的食譜試圖加載對應於當前節點的平臺系列配方見。但是，對於ChefSpec，除非您特別告訴ChefSpec假冒哪種節點，否則不會設置該數據。換句話說，node['platform_family']是nil，所以它試圖包含一個名爲build-essential::(nothing)的配方，這是無效的。

爲了解決這個問題，你可以設定值platform_family：

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

或（首選），你可以告訴ChefSpec冒充節點：

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