===== Karma =====

A "Javascript **unit** test runner".
This means that Karma executes unit tests, written in javascript.

This happens as following:
  * Start up a NodeJS
  * Launch the real browser via a [[http://karma-runner.github.io/2.0/config/browsers.html|browser launcher]]
  * Execute JavaScript code on the NodeJS browser and check the results.


Only **UNIT TESTS** are executed here - means only separate functions will be executed, **no complete applicaiton** is executed.

Compared to that protractor executes the application and runs the tests against it. (End-To-End tests)
