Backend Go testing

Status - Accepted 🟢

Our backend is compromised out of different submodules. We need a strategy to minimize time to identify and fix software bugs.

We create a test file for each file in our code.

We use the standard file ending of '_test.go' for the test file as it is described in the official tutorial.

Finding bugs earlier in the development lifecycle.

More time used per function because of the tests that have to be written for it.
