Selenium和Python在雪豹

Question

I'm trying to use the stock Python (2.6.1) on Snow Leopard with Selenium. Being quite new to Python, I'm a at a bit of a loss for what I've done wrong, as this exact same process worked just fine on my ubuntu box:

1. sudo easy_install -U selenium
2. Create a simple test with Firefox Selenium UI, and export it as Python WebDriver (as mytest.py)
3. $ python mytest.py (which results in:

This error message:

E

One thing worth noting is that when I ran "sudo easy_install -U selenium", I did get a warning:

Answer 1

Check your Firefox binary location first. Does it placed at here: /Applications/Firefox.app/Contents/MacOS/firefox ?

For more information, please check this page: http://code.google.com/p/selenium/wiki/FirefoxDriver

Answer 2

I know nothing about Selenium but the traceback indicates that it doesn't have a usable path to Firefox.

You will need to change its configuration/profile file to give it a path to an executable version of Firefox.

The profile as it stands probably has the default location of Firefox on a linux box (hence why it works on Ubuntu). But it wont be at this location on OSX.
