+Backend unit-tests
+==================
+
+We expect to have a very good test coverage for the code we produce, similar to what is there in
+the Kea project. Each file whatever.go is supposed to be accompanied with whatever_test.go.
+To run such unit-test, please use:
+
+.. code-block:: console
+   go test
