ChefSpec for registry_data_exists guard

[MAN98]

Hi - How do you write the ChefSpec test when you use the registry_data_exists method as a guard? I don't see any example on how to test or stub that method. When I run ChefSpec it always failing with the following error message:
Chef::Exceptions::Win32RegKeyMissing:
Registry key HKLM\SOFTWARE\Regkey does not exist

Here's how I use that method:
registry_key 'Set Data value to Auto' do
key 'HKLM\SOFTWARE\RegKey'
values [{ name: 'MaintenanceGroup', type: :string, data: 'Auto' }]
recursive true
action :create
only_if { registry_data_exists?('HKLM\SOFTWARE\RegKey', { name: 'MaintenanceGroup', type: :string, data: '' }, :machine) }
end

[MAN98]

I am looking at something that was suggested here: #514. Do I simply replace registry_value_exists? with registry_data_exists?

[MAN98]

I got passed the error message:
Chef::Exceptions::Win32RegKeyMissing:
Registry key HKLM\SOFTWARE\Regkey does not exist

by adding the registry_key_exists? guard in the registry_key resource and mock it in the corresponding ChefSpec test:

in my recipe:

registry_key 'Set Data value to Auto' do
key 'HKLM\SOFTWARE\RegKey'
values [{ name: 'MaintenanceGroup', type: :string, data: 'Auto' }]
recursive true
action :create
only_if { registry_key_exists?('HKLM\SOFTWARE\RegKey', :machine) }
only_if { registry_data_exists?('HKLM\SOFTWARE\RegKey', { name: 'MaintenanceGroup', type: :string, data: '' }, :machine) }
end

in my spec file:

before(:all) do
      RSpec::Mocks.with_temporary_scope do
        allow_any_instance_of(Chef::Resource)
          .to receive(:registry_key_exists?)
          .with('HKLM\SOFTWARE\RegKey', :machine)
          .and_return(true)

        allow_any_instance_of(Chef::Provider)
          .to receive(:registry_key_exists?)
          .with('HKLM\SOFTWARE\RegKey', :machine)
          .and_return(true)
      end
    end

But I am not sure if that's really how it should be done or if I still need to mock the registry_data_exists? guard. Still looking for some guidance.
