It would useful to be able to define clean-up steps/post-conditions for keyword tests. This could be implemented as a new test step section at the bottom that always gets called regardless of whether...
That would be great. I did look into the event handlers but calling the same handler for every test would get out of hand fast.
The current event handlers (onStartTest/onStopTest) are indeed not very useful because the aqTestCase.CurrentTestCase properly is set to null for event handlers, so you can't tell where they came from to decide what to clean up.
If there is something like this already in development then that's great! Looking forward to it in an upcoming release!
