Question: Test base in the production code

Hi people, 

I joined the project and I see test name dependency for the production code. Is it correct?

```
+--- com.github.badoo:RIBs:0.12.0
|    +--- com.github.badoo.RIBs:rib-android:0.12.0
...
|    +--- com.github.badoo.RIBs:rib-base:0.12.0 (*)
|    +--- com.github.badoo.RIBs:rib-base-test:0.12.0
