Test-suite have to cover most of opendedup-functionality

```
I am a bit surprised to be the first, who ask the Q:
- where is tests?
Am I a first one? 

Are some tests (unit-tests, integration, e.t.c) exists somewhere? If not - is 
it planned to add some basic tests for (for ex.) back compatibility.
