Re: [QF-Test] Memory leak when performing tests with datadriver

Hello Martin,

this is a rather specific question that might have been better placed
with our support. Please send followups to me, not the list. Still,
parts of this answer may be useful to others.

First we need to find out, whether memory is consumed in the Java VM
in which the browser is running or by the embedded browser itself.

Please add a call to the procedure


inside your loop so that the memory consumption for each iteration
gets documented. Then please send me a run-log for a complete
run with SUT crash.

Best regards,
