You don't. Karma is only for testing browser-based code. If you have a project with mocha tests on the backend and karma/mocha on the front end, try editing your package.json under scripts to set test to: mocha -R spec && karma run karma.con

Then, if npm test returns true, you'll know it's safe to commit or deploy.
