Execute unit tests as a part of CI process

[mykola-mokhnach]

We have to execute the set of basic unit and integration tests as a part of commit acceptance procedure.

@mykola-mokhnach What is the test strategy for other clients? Looking at the java client builds a while back, I could only see iOS tests being run on CI. If that is the case, we'd either have to refactor the way tests are written or update them to cater for minimum/maximum OS version support

[mykola-mokhnach]

Lets do the stuff step by step. Even one running integration test (but a stable one) would be very good. Also, unit test might be necessary for some custom helpers

[laolubenson]

Yeah i'm not sure if any unit tests exit atm or if they're merged into the integration test project. Will have a look an identify a test suite.

@akinsolb should we change the milestone on this one?

@mykola-mokhnach issue closed since it was handled under #557. If you have other ideas on how to proceed from her, please let me know. I know you prefer GH actions over azure pipeline.
