Karma best practices with AngularJS in a Spring MVC project

Question

I am currently working on a Spring MVC project where I use AngularJS in an interface. I want to use Karmafor unit testing.

I would like to get a link to learn Karma best practices with AngularJS in a Spring MVC project.

And it's great if someone can tell a way to get Karmato check without getting all the dependencies inside the directorynode_modules in my project directory.
