"""
Unit testing of the 'objects' Evennia component.

Runs as part of the Evennia's test suite with 'manage.py test-evennia'.

Please add new tests to this module as needed.

Guidelines:
 A 'test case' is testing a specific component and is defined as a class inheriting from unittest.TestCase.
 The test case class can have a method setUp() that creates and sets up the testing environment.
 All methods inside the test case class whose names start with 'test' are used as test methods by the runner.
 Inside the test methods, special member methods assert*() are used to test the behaviour.
