> MdePkg/Include/Library: Add UnitTestLib class
>
> From: Bret Barkelew <brbar...@microsoft.com>
>
> Add UnitTestLib class to MdePkg that provides services
> and macros to implement unit tests. These services and
> macros support the following features:
>
> * Create a Unit Test Framework
> * Add a Unit Test Suite to a Unit Test Framework
> + Support optional step that executes before a Unit
> Test Suite is started.
> + Support optional step that executes after a Unit
> Test Suite is finished.
> * Add a Unit Test to a Unit Test Suite
> + Support optional step that executes before a Unit
> Test is started.
> + Support optional step that executes after a Unit
> Test is finished.
> * Run all unit tests added to a Unit Test Framework
> * Save Unit Test Framework state to persistent storage
> * Support assertion checks in a unit test for TRUE,
> FALSE,
> EQUAL, MEM_EQUAL, NOT_EFI_ERROR, STATUS_EQUAL, and
> NOT_NULL.
> * Support generation of log messages at ERROR, WARN,
> INFO,
> and VERBOSE levels.
