The environments are fully flexible so you can set up pretty much anything you want in the way of environments. The only limit in combinations is the different browsers and operating systems which Selenium has support for.
So where to start? Firstly have a look at my other blog posts on getting Selenium Grid set up and running (links at the bottom of the page).
The Grid Hub will need to know about the environments you want to have. This is configure in the grid_configuration.yml file. This the config I am using:
hub: port: 4444 remoteControlPollingIntervalInSeconds: 180 sessionMaxIdleTimeInSeconds: 300 environments: - name: "Firefox35 on Linux" browser: "*firefox" - name: "Firefox36 on Linux" browser: "*firefox" - name: "IE6 on WindowsXP" browser: "*iehta" - name: "IE7 on WindowsXP" browser: "*iehta" - name: "Firefox35 on WindowsXP" browser: "*firefox" - name: "Firefox36 on WindowsXP" browser: "*firefox"
For the different version of Firefox I didn't install them per se as you can only really have one Firefox installed at a time. On Linux I downloaded the .tar.bz2 files from Mozilla and just extracted them. On Windows I used the Portable Apps versions of Firefox as would allow me to install independent of Firefox that don't mess with the registry and stomp on each other.
For each different browser you want to have available on an Operating System you need to have a separate remote control running (though there is bug open for this). To tell the remote control where to find the different Firefoxes I added the relelvant path to the Firefox executable to the path before launching the remote control. You can see some examples below; the main gotcha is ensuring that the port numbers don't clash and that you change the IP address to the current host (I am researching how I could make this automatic if you have any ideas please let me know).
Firefox 3.5 on Linux:
cd Desktop/selenium-grid-1.0.8/ export PATH="$PATH:/home/user/Desktop/firefox35/" ant -Dport=5555 -Dhost=172.24.128.70 -DhubURL=http://172.24.128.68:4444/ -Denvironment="Firefox35 on Linux" -DseleniumArgs="-multiWindow" launch-remote-control
Firefox 3.5 on Windows:
cd c:\selenium-grid-1.0.8 path %path%;C:\Firefox35\App\Firefox C:\apache-ant-1.8.2\bin\ant.bat -Dport=5555 -Dhost=172.24.128.76 -DhubURL=http://172.24.128.68:4444/ -Denvironment="Firefox35 on WindowsXP" -DseleniumArgs="-multiWindow" launch-remote-control
IE6 on Windows:
cd c:\selenium-grid-1.0.8 C:\apache-ant-1.8.2\bin\ant.bat -Dport=5554 -Dhost=172.24.128.76 -DhubURL=http://172.24.128.68:4444/ -Denvironment="IE6 on WindowsXP" -DseleniumArgs="-multiWindow" launch-remote-control
From those you should be able to figure out how to do most other broswers.
Once you have started them up you should be able to see them all connected to the hub when you have a look at its console (http://

So basically that is what you need to do to Selenium Grid working with multiple environments. Any questions, comments, suggestions, etc there is the comments section at the bottom of this post.
