Yes it was running to 24 hours , no hibernate or sleep set on this computer
The webpage updated after each test with the test number and next testing time
It was still running I when I checked this morning with 2 iterations to go
It did complete as the page updated to a test complete message and the buttons all changed to just one centered button which I think said Complete & Escape.
I clicked the button and I belive the page changed to 'My results' page
