Chrome is used to launch a special mode of Firefox (a mode in which the applications have various privileges with fewer security restrictions). So, the fact that Firefox is launched instead of Google Chrome is normal.
If you want to launch Google Chrome, you will have to use some other browser other than Chrome.
Using Selenium RC in interactive mode, with something like this :
$ java -jar selenium-server.jar -interactive
and using the getNewBrowserSession command incorrectly like this :
I get the list of browsers that are supported and not supported:
23:43:09.317 INFO - Got result: Failed to start new browser session: Browser not supported:
(Did you forget to add a *?)
Supported browsers include:
on session null
So, you should be able to launch Google Chrome using *google chrome instead of *chrome.
This is not done on Windows. And I cannot find anything in the documentation to back me up. Still, with a bit of luck, this might help you.
Anyway, happy learning!
