'''
An object grouping a collection of tests. It provides tags which enable
filtering during list and run selection. All tests held in the suite must
have a unique name.
..note::
The :func:`__new__` method enables collection of test cases, it must
be called in order for test cases to be collected.
..note::
To reduce test definition boilerplate, the :func:`init` method is
forwarded all `*args` and `**kwargs`. This means derived classes can
define init without boilerplate super().__init__(*args, **kwargs).
