@ -322,6 +322,30 @@ The :mod:`test.support` module defines the following functions:
assert s.getvalue() == "hello"
.. function:: import_module(name, deprecated=False)
This function imports and returns the named module. Unlike a normal
import, this function raises :exc:`unittest.SkipTest` if the module
cannot be imported.
Module and package deprecation messages are suppressed during this import
if *deprecated* is :const:`True`.
.. versionadded:: 3.1
.. function:: import_fresh_module(name, blocked_names=None, deprecated=False)

``sys.modules`` cache is bypassed temporarily, and the ability to import the
modules named in *blocked_names* is suppressed for the duration of the import.
Module and package deprecation messages are suppressed during this import
if *deprecated* is :const:`True`.
.. versionadded:: 3.1
The :mod:`test.support` module defines the following classes:
.. class:: TransientResource(exc[, **kwargs])
