Yes, we can create a host test specific lib if no better ways.

Can we use a host test specific RngLib?

Subject: CryptoPkg host test broken due to smoketest for RDRAND

 

All crypto host tests which consumed randlib broken due to:

https://github.com/tianocore/edk2/pull/5714

Not sure why this issue not reported  by CI when merge this PR.

 

The reason is that the ```BaseRngLibConstructor``` of rnglib is not called in host test, so ```mRdRandSupported``` is not enabled.

Then the Crypto API calls ```GetRandomNumber*``` will fail.

GetRandomNumber64 (

  OUT     UINT64  *Rand

  )

{

  ……

  if (!ArchIsRngSupported ()) {

    return FALSE;

  }

 

Is there a way to let unit test host to call the constructors correctly?
