如何使用InSpec创建上下文？

Question

我正在使用InSpec创建我的测试。这是我对Apache的测试：

require 'inspec'

if os[:family] == 'redhat'

  describe package 'httpd' do
    it { should be_installed }
  end

  describe service 'httpd' do
    it { should be_enabled }
    it { should be_running }
  end

  describe file '/etc/httpd/conf/httpd.conf' do
    it { should be_file }
  end
end
describe port(80) do
  it { should_not be_listening }
end

describe port(9000) do
  it { should be_listening }
end

我的问题与上下文相关。在使用InSpec之前，我使用了ChefSpec，我喜欢它创建上下文和输出显示上下文的方式。对于上面的示例，输出如下：

System Package
     ✔  httpd should be installed
  Service httpd
     ✔  should be enabled
     ✔  should be running
  File /etc/httpd/conf/httpd.conf
     ✔  should be file
  Port 80
     ✔  should not be listening
  Port 9000
     ✔  should be listening

我希望在输出中包含家庭风格或版本或arch，以便了解并获得更清晰的测试输出。

有什么建议吗？

Answer 1

首先，ChefSpec和InSpec做的是完全不同的事情，所以两者是可以比较的。其次，虽然InSpec支持一定程度的RSpec语法兼容性，但它远不如ChefSpec或ServerSpec那么完整，这两个库都是完整的RSpec帮助器库。正如@Tensibai提到的，InSpec提供了自己的custom syntax for more complex tests。如果您特别想使用RSpec describe和context block系统或自定义RSpec格式化程序，我建议您改用ServerSpec。

我认为您正在寻找一种更好地控制输出的方法。如果是这样，Chef建议您使用expect语法。尽管他们说它的可读性不如should语法，但它是定制输出的唯一方法。

例如，如果运行此控件：

control 'Services' do
  title 'Check that the required services are installed and running.'
  if os['family'] == 'darwin'
    describe 'For Mac OS, the Apache service' do
      it 'should be installed and running.' do
        expect(service('httpd')).to(be_installed)
        expect(service('httpd')).to(be_running)
      end
    end
    describe 'For Mac OS, the Docker service' do
      it 'should be installed and running.' do
        expect(service('docker')).to(be_installed)
        expect(service('docker')).to(be_running)
      end
    end
  end
end

您将获得以下输出：

  ×  Services: Check that the required services are installed and running. (1 failed)
     ×  For Mac OS, the Apache service should be installed and running.
     expected that `Service httpd` is installed
     ✔  For Mac OS, the Docker service should be installed and running.
