# Powershell script for cleaning up remaining browser and selenium server processes on the CI servers
#
# Author: Martin Stockhammer <martin_s@apache.org>  
# Date  : 2017-04-30
#
# Descriptions:
#  Stopps processes related to the selenium checks, if they were not stopped by the selenium server, because
#  the job was aborted.
#  The script cannot determine, which of the processes are started by the current job, so if there are
#  parallel jobs running on this server that start processes with the same name and user, these
#  will be stopped too.
#
#  Per default the script will stop "firefox.exe","iexplore.exe","chrome.exe"
#  and the processes "java.exe","mshta.exe" if their commandline arguments contain "selenium-server"
# 
# Parameters:
#  -Verbose              : If set, more output will be printed
#  -Browsers proc1,proc2 : The list of executables that define the browser processes, that are started by selenium
#  -SeleniumProcesses    : The list of processes with the string "selenium-server" in the commandline arguments
