Question

我的食谱安装了dynatrace模块并启用它：

include_recipe 'dynatrace::wsagent_package'

apache2_module 'dtagent_module' do
  module_name 'dtagent_module'
  filepath node['dynatrace']['apache_wsagent']['linux']['agent_path']
  action [:enable]
end

我的spec文件包含以下内容：

  it 'creates /opt/dynatrace/agent/lib64/libdtagent.so file' do
    expect(chef_run).to render_file('/opt/dynatrace/agent/lib64/libdtagent.so')
  end

当我运行Rspec时，它失败并出现以下错误：

$ rspec -f d ./spec/unit/recipes/apache_spec.rb[1:4]

Run options: `include {:ids=>{"./spec/unit/recipes/apache_spec.rb"=>["1:4"]}}`

需要一些帮助来确定导致我的规格失败的问题。

根据您的描述，问题不是由于未受影响的资源而失败。

您的chefspec运行失败，因为Chef运行中没有资源创建文件/opt/dynatrace/agent/lib64/libdtagent.so

从https://github.com/Dynatrace/Dynatrace-Chef/blob/master/recipes/wsagent_package.rb的外观来看，包含的配方可能会通过提取存档/ tar来创建该文件。由于这是副作用，因此无法使用单元测试直接测试。

您似乎正在编写一个包装器手册，将两个功能粘合在一起。

诸如带有serverspec的测试厨房之类的工具可能更适合您正在编写的集成测试。

Rspec无法使用未获得资源
