Go to http://fitnesse.org/FitNesseDevelopment.DownLoad and download the the latest fitnesse.jar. Create a directory c:\program files\fitnesse\. Copy the downloaded fitnesse.jar into directory c:\program files\fitnesse. fitnesse.jar is an executable jar file so just double click this file and it will install itself.
Download Selenium Remote Control (Selenium RC)
Go to http://selenium-rc.openqa.org/download.jsp and download the latest version (1.0.3 at the time of writing this page). Unpack the zip into c:\program files\selenium\ directory. Current version for Selenium-RC is 1.0.3 and these instructions are written assuming you are using this version.
Create a smart start script
Copy and paste following script into a file called run.vbs under the directory “C:\Program Files\selenium\selenium-server-1.0.3”. This script will start both FitNesse servers and Selenium remote control servers on their default ports 8000 and 4444 respectively. This script will ONLY start these processes if these processes are not running, so this script can be safely run any time.
PS: Please note that this script is starting Selenium in an experimental Proxy Injection Mode which lets you run your web test across multiple domains. If you don’t want to use this feature feel free to change this start script.
