杂散 ruby 变量的 chefspec 测试

chefspec testing for stray ruby variable

在这里,我在变量中返回提供者的状态,我如何在 chefspec 中模拟该状态以进行测试?

ret = yum_package 'blah' do
   action :install
end   
cookbook_file "/etc/init.d/blah" do
   source "blah"
   only_if { ret.updated_by_last_action? }
end

我怀疑这项工作,ret.update_by_last_action? 是在编译时计算的,而提供者没有 运行。

推荐的方法是像这样使用 notifications

yum_package 'blah' do
   action :install
   notifies :create,"cookbook_file[/etc/init.d/blah]", :immediately
end   

cookbook_file "/etc/init.d/blah" do
   action :nothing
   source "blah"
end

然后您可以期待 notification is sent 并且文件已创建。

规格示例:

blah_package = chef_run.yup_package('blah')
expect(blah_package).to notify('cookbook_file[/etc/init.d/blah]').to(:create).immediately
expect(chef_run).to render_file('/etc/init.d/blah')
