I know this is quite an old post, but for posterity's sake:
I was trying to do the same thing. Specifically I had a .pas file for a COM object that I was trying to unit test. When trying to create an instance in the testrunner I would get a runtime error 217 after TAutoObjectFactory.Create in the unit's initialization section.
It sounds like runtime error 217 means an uhandled exception in a unit's initialization.
From the following post it looks like for TAutoObjectFactory.Create to be successful, the dll or exe must contain a type library.

The dll project that originally contained the COM object's .pas had this line
{$R *.TLB}
so I added a similar line to my testrunner that was having the runtime error 217
{$R '..\MyComObject\MyComObject.tlb'}
After including the tlb in the test runner, I was able to create an instance of the com object using the .pas file.
