Class-D Personnel

In my previous test run the filter crashed at the test Wdf - Kmdf Fault Injection Test

This test is actually amazing! Summary:

For each DDI that has been configured for fault injection, the WdfFiTester tool returns an NTSTATUS code of STATUS_UNSUCCESSFUL. The driver is expected to handle the failure.

That is really cool! It means, that it uncovers continued code execution where a faulty return code of a WDF function call isn't caught properly, which may lead to a crash (as demonstrated in my last run). I think I've nailed down the issue in my code and just started another run. Fingers crossed

Ahoi, for pairing alone you don't need AirBender, try to restart Shibari and don't click into the console window while executing the commandlet.

Dammit, almost...

What's going on here....

Oh How did I manage to provoke that. Well, back to fixing stuff

@Poosaurus you too

@tulio150 @ryantburke done, welcome!

Oh yes, give me more green! All the green tick marks!

@pejman you simply subscribe to the FeedbackReceived event.

Jo, it's WHQL-o-clock

This time the filter is my primary test subject. Fingers crossed!
