Microsoft IOStress tests

I’m currently testing my driver and I have little experience in testing filter drivers.
As I understand, testing with Microsoft IOStress test suite is recommended.

Could someone shed some light on those tests?
I’ve got no idea what they are doing.

I’m not even sure what’s the purpose of those tests. Should I just run them and make sure theres no BSODs?

I’m currently running them and all I see is poping windows and a lot of weird messages and prints. I got no idea if they are actually doing something, if theres a problem in my setup or if my driver doesn’t behave well.

It’s seems to be configurable, but I have no idea how to set the options (what’s the recommended time for stress, which tests should I include etc…).

I’ve googled a bit, but without luck. Didn’t find a lot of documentation (or any at all).
Any kind of information would be helpfull, and if I’m missing something obvious please point me to it.

Thanks.
