 Create first test

-We want to test the model first::
+Hands on! Let's write a first basic test.

+E.g. a small model with a bit logic::
 
    mkdir -p Tests/Unit/Domain/Model
    cp Resources/Private/CodeExamples/Tests/Unit/Domain/Model/AddressTest.php \
       Tests/Unit/Domain/Model/AddressTest.php

    ./vendor/bin/phpunit Tests/Unit/
 
+What's in the test?
+-------------------
+
+#. We have one PHP class `AddressTest`.
+
+#. Two public methods.
+
+#. The methods are annotated with `@test`.
+
+#. Methods create an instance of the class to test.
+
+#. Methods call an `assert*()` method.
