Rspec:无法解析环境rp_env

Question

我是rspec傀儡的新手，我从测试开始：

我写了这段代码：

describe 'rcjenkins' do
  let(:facts) do
    {
      :osfamily => 'RedHat'
    }
  end
  let(:pre_condition) do
    "$facts = #{facts}"
  end

  let(:params) do
    {
      :host => "127.0.0.1",
      :github_token => "valor",

    }
  end
  it do
    is_expected.to contain_class('rcjenkins::nginx')
  end
end

哪一个应该测试：

class rcjenkins($host, $github_token) {
  include rcjenkins::package

  class { 'nginx': }

  nginx::resource::upstream { 'jenkins':
    members => [
      'localhost:8080'
    ]
  }

  nginx::resource::vhost { $host:
    proxy => 'http://jenkins'
  }

  nginx::resource::location { 'jenkins_root':
    ensure         => present,
    vhost          => $host,
    location       => '/status',
    location_alias => '/usr/share/nginx/html'
  }

这更像是一次“测试”，但事情一直在失败。我得到了：

  1) rcjenkins Treco should contain Class[rcjenkins::nginx]
     Failure/Error: is_expected.to contain_class('rcjenkins::nginx')

第39行是is_expected.to contain_class('rcjenkins::nginx')。有人知道发生了什么吗？

编辑:我也注意到了，任何我更改测试的地方，都会给我同样的错误。我错过了什么？rp_env是什么？

Answer 1

OP还询问了有关rp_env的情况。

环境rp_env代表“Rspec-傀儡环境”，是Rspec-傀儡本身添加的环境的假值。

它是在代码中定义的这里。

如果您希望自己在Rspec-傀儡代码中设置环境，那么有一个有用的post 这里可以解释如何做到这一点。

Answer 2

删除或修复您的pre_condition，它不会生成有效的木偶清单：

let(:pre_condition) do
  "$facts = #{facts}"
end

如果Ruby变量facts是{ :osfamily => 'RedHat' }，那么这将生成一个木偶清单，如下所示：

$facts = {:osfamily=>'RedHat'}

Os族哈希键前面的冒号在木偶清单中无效(它必须是一个字符串，例如'osfamily')。

我不认为有任何理由在这里设置pre_condition，您的let(:facts)应该足够了。
