Set config's 'browsers' property in the command line in karma runner - angularjs

Question

I usually use browsers=['PhantomJS'] for running my specs with karma because it's faster than chrome and I find a bit annoying when chrome opens the browser in front of the window on every boot.
But when I have a bug and I need to debug, I change karma.conf.js browsers to ['Chrome'].
I would like to set this property when I start karma, something like: 'karma start --browsers=[Chrome]'.
Is this posible?

Answer 1

you just have to use the --browsers parameter and it'll overide your config file browsers part.
$ karma start config/testacular.conf.js --browsers Chrome
where Chrome is the name of the browser or a path to a binary.
For example, I have only a small Qt browser configured. if I use the line above, it runs Chrome instead.
INFO [karma]: Karma server started at http://localhost:9876/
INFO [launcher]: Starting browser Chrome
INFO [Chrome 24.0 (Linux)]: Connected on socket id DxbVJNX0jIoe1CbaWf9V
Chrome 24.0 (Linux): Executed 74 of 74 SUCCESS (0.443 secs / 0.232 secs)
...
or, for example, I have firefox beta, aurora and release in my home. I run beta with:
$ karma start config/testacular.conf.js --browsers ~/firefox/firefox
$ karma start --help
