# This class does not inherit from unittest.TestCase, because it would
# interfere with the "yield" mechanism that automatically generates test, see
# http://stackoverflow.com/questions/6689537/nose-test-generators-inside-class
# Therefore, it needs to be named "test_..." or "Test_...", so nose can pick
# it up by name, otherwise the tests would not be executed.
