angularjs unittest

0. prepare project for unitest
We need angular-mocks.js. You can download it from http://angularjs.org and https://code.angularjs.org/1.4.1/. I recommend to read the post before following this post if you are not familiar with angularjs and nodejs.

1. configure Karma test-runner
You should configure karma per each project respectively . You can see the following questions.
$ karma init karma.config.js

karma.config.js is created.

2. create unit test file in tests

3. start karma

We used jasmine testing framework. You may noticed that second test case is failed. Whenever you make changes, Karma automatically detect changes and run all unit test.
