Hi Sophia,

Unfortunately, I am not conversant with the Google Test framework. I will need to get around to understanding it at some point.

However, there is a recent PR that adds some tests. Can you take a look at the patch at: https://github.com/tianocore/edk2/pull/10833/commits/4eeeb1434820718ace1670d9429a867fe5e8c9b7
to see if it helps, please?

Regards,

Sami Mujawar

Subject: [edk2-devel] ACPI table generator unit test
Hi,

I plan to use EDK2 unit test framework (https://github.com/SophiaWang-Google/edk2/tree/master/UnitTestFrameworkPkg) to test ACPI table generator, such as https://github.com/tianocore/edk2/blob/master/DynamicTablesPkg/Library/Acpi/Arm/AcpiGtdtLibArm/GtdtGenerator.c

However, ACPI table generator only has 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
  )

So if we want to use GoogleTest gMock to unit test ACPI table generator, I guess we need to expose API :
STATIC
EFI_STATUS
EFIAPI
BuildGtdtTable (
  IN  CONST ACPI_TABLE_GENERATOR                  *CONST  This,
  IN  CONST CM_STD_OBJ_ACPI_TABLE_INFO            *CONST  AcpiTableInfo,
  IN  CONST EDKII_CONFIGURATION_MANAGER_PROTOCOL  *CONST  CfgMgrProtocol,
  OUT       EFI_ACPI_DESCRIPTION_HEADER          **CONST  Table
  )
to non-static

Please let me whether this is the approach upstream target for, or any better solutions on this?

Thank you,
Sophia
