Re: [QF-Test] Run-Log Screenshot give out a black picture

Please have look at FAQ14:


"Create screenshot of the whole screen" takes a screenshot of the real desktop containing all visible windows with all post processing effects like antialiasing or cleartype. If not desktop is present, QF-Test cannot take those screenshots.

"Create screenshot of individual windows" works well because QF-Test renders the window into an offscreen buffer. In this case it does _not_ take a real screenshot of the application window, thus those screenshots do _not_ look like the real application, because all post processing effects are missing.


However, it is not recommended to run GUI tests in a locked user session or in the service session, like described in FAQ14.


Best regards,

Subject: [QF-Test] Run-Log Screenshot give out a black picture


Hello everybody,

i have a simple question about the Run-logs of qftest.

I checked the option "Create screenshot of the whole screen" but i get only a black picture. The option "Create screenshot of individual windows" works very well. What can i do? Can i configurate this option anywhere?


Remark: We have include qftest into a Jenkins job with an Ant-Build.

This is a snippet of code:


<exec executable="${qftest}" failonerror="true" resultproperty="returncode">
<arg value="-batch" />
<arg value="-compact" />
<arg value="-runlog" />
<arg value="${logdir}\+b" />


Best regards
