how to tst the "erase " functionality of an rpm

[Jennis Pruett]

I am not allowed "root" on any system, but we build rpms to
give to our sysadmins. 

My problem:  Using my .spec file, I create rpms.  
But I can't find any way to test what will happen when the rpm
is obsolete and the systems folks have to do the rpm -e  rpm_that_I
built_at_one_time_in_antoher_life.rpm


I can cpio the rpm, and use the rpm -qip to check it. But there is no way
that I know
of, to verify that the erasure will actually remove everything.  

Anyone have an idea?

Thanks,
J
