Test Kitchen是Chef的集成测试框架。它支持编写测试配方,一旦使用菜谱实例化和融合了这些虚拟机,它们便可以在VM上运行。测试配方可以在该VM上运行,并且可以验证是否一切都按预期进行。
ChefSpec是仅模拟Chef运行的东西。测试厨房启动真实节点并在其上运行Chef。
步骤1-安装测试厨房Ruby Ruby和测试厨房vagrant gem,以使测试厨房能够使用vagrant进行测试。
$ gem install kitchen
$ gem install kitchen-vagrant
步骤2-设置测试厨房。这可以通过在cookbook目录中创建.kitchen.yml来完成。
driver_plugin: vagrant
driver_config:
require_chef_omnibus: true
platforms:
- name: ubuntu-12.04
driver_config:
box: opscode-ubuntu-12.04
box_url: https://opscode-vm.s3.amazonaws.com/vagrant/opscode_
ubuntu-12.04_provisionerless.box
suites:
- name: default
run_list:
- recipe[minitest-handler]
- recipe[my_cookbook_test]
attributes: { my_cookbook: { greeting: 'Ohai, Minitest!'} }
在上面的代码中,一部分定义了流浪者需要启动虚拟机,还定义了您希望Omnibus在目标节点上安装Chef。
第二部分定义要测试食谱的平台。流浪者将始终创建和销毁新实例。您不必担心使用Vagrant文件启动的无用虚拟机的副作用。
可以将测试厨房视为一个临时环境,它有助于在类似于生产的临时环境中运行和测试食谱。启用测试厨房后,可以确保给定的代码在实际部署到测试,预生产和生产环境之前可以正常工作。许多组织都遵循测试厨房的这一功能,然后将菜谱置于实际的工作环境中。
以下是“测试厨房工作流程”中涉及的步骤。
使用以下代码创建食谱。

驱动程序-它指定用于管理机器的软件。
供应器-提供有关Chef如何运行的规范。我们正在使用Chef_zero,因为它可以模拟本地计算机上的Chef服务器环境。这允许使用节点属性和Chef服务器规范。
平台-这指定目标操作系统。
套件-它定义了要在虚拟环境上应用的内容。在这里,您定义了多个定义。在此定义运行清单,该清单指定要运行的配方以及需要运行的顺序。
