Use notepad to create a file named whatever you like, but using the .bat file extension. i.e.,
Copy and paste the code below into the file:
START java -jar C:\selenium\selenium-server-standalone-2.31.0.jar -port 4445 -firefoxProfileTemplate "C:\ffprofiles\selenium" -htmlSuite "*chrome" "http://www.google.com" "C:\path\to\script\suite-exampletests.html" "C:\path\to\script\report\report.html"
Modify the variables for your script need and save the file. Either double click the file run it, or setup a Windows Scheduled Task to run it at a specific time.
Note: There are many articles on the internet to show you how to setup your own custom Firefox profile, which is HIGHLY recommended.
