------------
As your collection of doctest'ed modules grows, you'll want a way to run all
their doctests systematically. Prior to Python 2.4, :mod:`doctest` had a barely
documented :class:`Tester` class that supplied a rudimentary way to combine
doctests from multiple modules. :class:`Tester` was feeble, and in practice most
serious Python testing frameworks build on the :mod:`unittest` module, which
supplies many flexible ways to combine tests from multiple sources. So, in
Python 2.4, :mod:`doctest`'s :class:`Tester` class is deprecated, and
:mod:`doctest` provides two functions that can be used to create :mod:`unittest`
test suites from modules and text files containing doctests. These test suites
can then be run using :mod:`unittest` test runners::
their doctests systematically. :mod:`doctest` provides two functions that can

containing doctests. These test suites can then be run using :mod:`unittest`
test runners::
