Karma test runner - fails to capture chrome

I'm using Yeoman to generate an AngularJS app. Running the grunt serve to preiview my app works fine, but when i try to run the tests using grunt test I get the following error on my console:

node v0.10.23
Karma version: 0.10.8

What am I missing?

Changing the default port (8080) to 9876 in karma.conf.js file solved the issue for me
