new_resource chefspec 测试中的作业

Question

我被困在一个 chefspec 测试中，该测试进入我的 lwrp 下面并断言它创建了一个目录。

describe 'mw-tomcat::chefspec' do

  let(:chef) do
    ChefSpec::SoloRunner.new(step_into: ['mw_tomcat_tree']) do |node|
      node.set['mw']['domain'] = domain
      node.set['mw']['gemrepo'] = gemrepo
    end
  end

  let(:chef_run) { chef.converge(described_recipe) }

  it 'creates the catalina_base directory' do
    expect(chef_run).to create_directory('/apps/bweb/apps/instance1')
  end

done

如果我取消注释下面的行，测试会成功，但在尝试从 new_resource.settings

获取值时失败

action :create do
  settings = new_resource.settings
  catalina_base=settings['catalina_base']
  #catalina_base='/apps/bweb/apps/instance1'

  directory "#{catalina_base}" do
    mode 0755
    owner settings['user']
    group settings['group']
    recursive true
    action :create
  end

end

在 chefspec 中有没有办法传入上面的 new_resource 值？

感谢您的帮助。

正如 this 非常详细的 ChefSpec 错误报告中所述，您尝试执行的操作可能是不可能的，因为 new_resource 对象实际上是在运行时间动态创建的。

如果您决定让它工作，可以使用 pretty complex workaround，但是目前首选的方法是将您的 LWRP 转换为 HWRP 并使用标准 RSpec 方法进行模拟输入。
