Puppet 中的 TDD Hiera 哈希

Question

spec/classes/test_spec.rb

require 'spec_helper'

describe 'test' do
  let(:hiera_data) { { :a => 'hello' } }

  it { should contain_file('/tmp/hello') }
end

manifests/init.pp

class test {
  $a = hiera('a')

  file {"/tmp/$a":}
}

结果：

[vagrant@vm-one test]$ rspec

Answer 1

看起来所有你的散列文字格式不正确。

尝试

let(:hiera_data) do
  { :a => 'hello', :b => { :c => 'world' } }
end
