In order to test a certain web page in all of my development browsers, I wrote a simple shell script that will open a new instance of each of my browsers and automatically point it to a given URL.

This script is designed for OSX and will likely need some tweaks for a Linux distribution (or perhaps a complete rewrite) but the concept can be easily transferred.

browser-test.sh

# $1: URL

open -a "/Applications/Google Chrome.app" $1 -g -n
open -a "/Applications/Google Chrome Canary.app" $1 -g -n
open -a "/Applications/Safari.app" $1 -g -n
open -a "/Applications/Webkit.app" $1 -g -n
open -a "/Applications/Firefox.app" -g $1 -g -n
open -a "/Applications/FirefoxAurora.app" -g $1 -g -n
open -a "/Applications/Opera.app" $1 -g -n
open -a "/Applications/Opera Beta.app" $1 -g -n

I have configured the script to work for Chrome and Canary (Nightly), Safari and Webkit (Nightly), Firefox and Aurora (Nightly) and finally Opera and Opera Beta (Nightly).

On my setup I additionally load an extra app called "CoRD" which is used to connect to remote Windows machines for Internet Explorer testing.

browser-test.sh

open -a "/Applications/CoRD.app" -g -n

The -g option after each open command tells the given app to open in the background. Finally the -n switch will force a new instance of the browser, even if you already have one running, so that the browser is in a clean state to test with.

Finally I symlink this file to my /usr/local/bin directory so that the script is always available on my PATH.

Terminal

$ cd /usr/local/bin
$ ln -s browser-test ~/path/to/browser-test.sh
$ chmod a+x browser-test

Complete these steps in order and you will be able to call browser-test from any directory in the terminal.

Terminal
