i am using simpletest as my php unit test framework.

i put all my test cases into a single all\_tests.php file

however, because of the tendency of our developers to use firefox to run the all\_tests.php, we tend to miss out on fail cases that are browser specific, especially ie7.

is there a way that when somebody browse our all\_tests.php in firefox, it will trigger automatically an ie window to open for the same page?
