test: update test code for the first showcase.

To show the result, we use efl library.

Most linux distribution supports efl library from their package repo,
you can easily install efl from its package repo:

Ubuntu:
$ apt-get install libelementary-dev

Or, please visit efl site to install EFL libarary manually:
