We running robot with:
p = subprocess.Popen(command, shell=True)
p.wait(timeout)

typically execution hang means that:

  1. you have started a process and its still running.
  2. you have open file handles that are not closed
  3. you have started a process and its output havent been “read” untill the whole output buffer’s end.

And these happen particularry in windows.

For scenario 1. I’ve had issues with certain applications that spawn child processes … Normal Robot Framework process stopping did not kill the child processes and i had to come up with my own keyword: robotframework-seleniumtestability/__init__.py at master · MarketSquare/robotframework-seleniumtestability · GitHub

Do check against any of these ?

Hi,
i also run into this Problem but I dont have any processes started or similair. Did you come up with a solution?

Recently noticed that on windows – if you have the existing report.html or log.html open in (at least) Edge browser - edge will lock that html file and RF keeps waiting before the browser or that particular tab is closed …
