Enforce tests for new changes

[eltongarbin]

Is your feature request related to a problem? Please describe.
We must consider tests when developing a library that supports other applications, because this brings some quality and facilitates new changes. So, I propose to configure this project to require 100% test coverage of what we are delivering.

Describe the solution you'd like

• Configure local and CI to run tests.
• Pull requests must be 100% changes coverage for merge.
