chef-infra - ChefSpec - 无法设置节点属性

Question

我对 nginx Recipe 做了一个简单的测试:

require 'spec_helper'

describe 'my_cookbook::nginx' do
  let(:chef_run) do
    ChefSpec::Runner.new do |node|
      node.set['nginx']['dir'] = '/etc/nginx'
    end.converge(described_recipe)
  end

  it 'should create configuration directory' do
    expect(chef_run).to create_directory("#{node['nginx']['dir']}")
  end

end

哪个失败了:

Failures:

  1) my_cookbook::nginx should create configuration directory
     Failure/Error: expect(chef_run).to create_directory("#{node['nginx']['dir']}")
     NameError:
       undefined local variable or method `node' for #<RSpec::Core::ExampleGroup::Nested_1:0x00000007993570>

我正在尝试按照 in the docs 的描述设置节点属性，我是否遗漏了一些明显的东西？

Answer 1

您可以设置节点属性。如果你查看堆栈跟踪，它会提示这一行:

expect(chef_run).to create_directory("#{node['nginx']['dir']}")

具体来说，#{node['nginx']['dir']}。您应该在这里使用静态值，否则您的测试毫无意义。将其更改为:

expect(chef_run).to create_directory('/etc/nginx')
