I want to execute a test today at 9pm. How to set this timing and date. So that the execution will start automatically at 9pm today without my present.
The simplier way is to schedule it within NeoLoad. Select your scenario, "Advanced..." button, then "Schedule a test" tab.
For information, you can schedule several tests by using the Windows Scheduler that calls a .bat files containing several call to NeoLoad command line options.
