我是Rspec-puppet的新手，我从测试写作开始：
我写了此代码：
describe 'rcjenkins' do
let(:facts) do
{
:osfamily => 'RedHat'
}
end
let(:pre_condition) do
"$facts = #{facts}"
end
let(:params) do
{
:host => "127.0.0.1",
:github_token => "valor",
}
end
it do
is_expected.to contain_class('rcjenkins::nginx')
end
end
应该测试的：
class rcjenkins($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"测试测试"，但事情一直在失败。我得到：
1) rcjenkins Treco should contain Class[rcjenkins::nginx]
Failure/Error: is_expected.to contain_class('rcjenkins::nginx')

第39行是is_Exped.to contain_class（'rcjenkins :: nginx'）。有人知道发生了什么吗？
编辑：我也确实注意到，我将测试更改为任何东西，给我同样的错误。我缺少什么？什么是rp_env？
删除或修复您的pre_condition，它没有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' }，则会生成像这样的木偶清单：
$facts = {:osfamily=>'RedHat'}
oSfamily哈希键前面的结肠在木偶清单中无效（必须是弦，例如'osfamily'）。
我认为没有任何理由在这里设置pre_condition，您的let(:facts)应该足够。
OP还询问了rp_env。
环境rp_env代表" RSPEC-PUPPET环境"，是Rspec-Puppet本身添加的环境的假价值。
它在代码中在此处定义。
如果您想在RSPEC-PUPPET代码中自己设置环境，则这里有一个有用的帖子来解释如何做。
