Request to check issue, which fails during "TestMethodCleanup" in "Directed FX Single Device Test" item

[CB.TH]

Hi, we are a company who develops UMDF2 based driver for our fingerprint sensor.

Our question is as below.

- We developed our UMDF2 based driver for fingerprint sensor, based on Windows 10 1903(19H1)

- When we do HLK test on our driver, it gets succeeded result on its operation as <Picture 1> in 'Directed FX Single Device Test' item.

- But it's actually ended with 'FAIL' result, during its "TestMethodCleanup' process.

- Is there any way to avoid this issue?

Below is the routine we checked this issue further. There's no problem as <Picture 4> by 'pwrtest command' testing.


1. We got 'FAIL' on "Directed FX Single Device Test" item of HLK Test.

<Picture 1> - The Client PC screen during HLK Test



<Picture 2> The Server PC Screen for HLK Test Result



2. As seen on <Picture 1>, we get "PASS" on its functional test, but get "FAIL" during "TestMethodCleanup" item after then. So, it's finally finished as "FAIL" in DFx item eventually as <Picture 2>.

3. When we checked Windows Event Viewer in our Client PC, we can check there's a crash occurred in "te.processhost.exe" as <Picture 3-3>

<Picture 3-1> "0xc0000374" error(STATUS_HEAP_CORRUPTION) is occurred in te.processhost.exe

<Picture 3-2> Event Viewer Details

<Picture 3-3> Event Viewer HLK Log



-> It was crashed by ArgumentNullException occured, due to get "NULL" argument on calling "BuildCopyFileInfosForDirectory" function inside te.processhost.exe

4. When we tried to do independent test by "pwrtest command" in command line, we can check DFx test is succeeded as below.
