Issue with cron scheduling python script which includes webdriver testcase
Hi,

Test a web page using selenium webdriver .python code is working fine when run from terminal.
problem comes when i use crontab to do the same.
These are the files.:
# crontab file :
crontab -l
49 12 * * * /home/sukhwinder/scheduler.sh
#file "scheduler.sh" :
#!/bin/sh
export DISPLAY=:0
cd /home/sukhwinder
python mainpro.py
# file "mainpro.py" :
#!/bin/bash
import time
import sys
import os
def main():
os.system('python /home/sukhwinder/Test_enabling_personal_blacklist.py')
time.sleep(10)
if __name__ == '__main__':
main()
#the error mailed by cron in /var/mail/root file is :
E
