为什么 Chefspec 找不到我的资源?

Why can't Chefspec find my resource?

我有一个 Spec 配方(除其他外)测试两个命令之一是 运行。如果已安装,第一个命令是 运行。如果不是,那么第二个应该是 运行.

然而,由于某种原因,该 Spec 配方并不是 "see" 第一个执行资源,尽管将确切命名的资源列为 "other execute resources"。但它确实看到并传递了第二个命令。

RSpec 输出如下所示:

gets admin key using getkey (FAILED - 1)
gets admin key using keyremoteclient [passed]

错误信息:

Failures:

 1) cookbook-forwarders::install_forwarder_package gets admin key using getkey
 Failure/Error: expect(chef_run).to run_execute('use getkey')

   expected "execute[use getkey]" with action :run to be in Chef run. 
   Other execute resources:

   execute[use getkey]

这部分错误没有意义,因为 确切的资源 存在!

    -->execute[use getkey]<--

菜谱部分是这样的

execute 'use getkey' do
  admin_passwd = getkey((node['splunk_forwarder']['key_name']).to_s)
  user 'root'
  only_if '/usr/local/bin/inst ls getkey -noname -noversion'
end

execute 'keyremoteclient' do
  admin_passwd = keyremoteclient((node['splunk_forwarder']['key_kgp']).to_s, (node['splunk_forwarder']['key_name']).to_s)
  user 'root'
  not_if '/usr/local/bin/inst ls getkey -noname -noversion'
end

我在 Spec 配方开头的 'only_if' 守卫中删除了命令:

  before do
    # stub command to get admin password using getkey
    stub_command('getkey(the_key_name)').and_return('xyz')
    # stub command to get admin password using keyremoteclient
    stub_command('keyremoteclient(the_kgp, the_key_name)').and_return('xyz')
    # stub check if getkey is installed
    stub_command('/usr/local/bin/inst ls getkey -noname -noversion').and_return(true)
    # stub check for already installed getkey package to use keyremoteclient
    stub_command('/usr/local/bin/inst ls getkey -noname -noversion').and_return(false)
end

规格配方部分如下所示:

it 'gets admin key using ykeykeygetkey' do
  expect(chef_run).to run_execute('use getkey')
end

it 'gets admin key using ykeykeyremoteclient' do
  expect(chef_run).to run_execute('keyremoteclient')
end

所以有几个问题;第一,您不能使用 stub_command 来存根 Ruby 代码,例如 getkey()。其次,您对两个守卫使用相同的命令,因此存根可能存在冲突。我建议重构您的代码以仅使用单个命令执行。您可能不需要为此编写单元测试,只需编写集成测试即可。
