Can I not to count some method in total Unit Test TestMethod time output?

I have a unit TestClass with several TestMethods in it (all of them are counting db procedure perfomance). Some method includes a large and heavy preparation part. Such as it's longer than method itself. Can I somehow make vs to not include it's time into total timeout of whole unittest method?

I try to use method with ClassInitialize attribute, but:

1. It brokes with ThreadAbortException, saying "Thread was being aborted".


2. As I Understand it's time is added to time of first test method.
