JMeter test plan automation

This automation script runs JMeter test plan with multiple input files specified by JMeter. It also has ability to send email before working on an input file and once the input file processing is complete.

• This is a working attempt for JMeter test plan automation using powershell.
• Powershell makes it portable for multi-OS environment.
• Script takes wildcard for input files, for each input file a directory is created in output folder.
  • All output files – .jtl, .png, jmeter.log from the run will be available in output folder
