Thanks Sami for the reply.

https://github.com/tianocore/edk2/pull/10833/files is indeed adding mock
configuration manager protocols for unit tests. But the issue for unit test
code cannot call the build function of ACPI table generator still exists.
Currently we only have two non-static function exposed

EFI_STATUS
EFIAPI
AcpiGtdtLibConstructor (
  IN  EFI_HANDLE        ImageHandle,
  IN  EFI_SYSTEM_TABLE  *SystemTable
  )

EFI_STATUS
EFIAPI
AcpiGtdtLibDestructor (
  IN  EFI_HANDLE        ImageHandle,
  IN  EFI_SYSTEM_TABLE  *SystemTable
  )

And IMO, we need to expose more functions as non-static for the ACPI table
unit test purpose. Please feel free to share your insights.

Best,
Sophia
