Code Coverage

Hi,

I am working on a filter driver that performs registry callbacks. It doesn't really fall under any specific kind of driver but is meant to capture events with the Windows registry. It is written in c++. I am trying to get a list of code coverage tools together that will cover both the user and kernel code for my driver.

Here is something I have so far:
Testwell CTC++
Tessy
Insure++
Cantata++
TestCocoon
COVTOOL
xCover
TruCov
BullseyeCoverage

I've found that Bullseye is pretty useful and integrates with Visual Studio which I like. What else to this list could I add or what on this list isn't worth checking out?

Thanks,

John
