CI - Integrate CI unit testing

Each class under test will have a dedicated test file.
Each test file is placed in a dedicated folder in extras/test/src . Such dedicated folder will also contain the mock (Fake) objects needed by the test.
Finally, an executable file will be generated for each test.
