Example module that is tested in :py:class`pyfakefs.example_test.TestExample`.
This demonstrates the usage of the
:py:class`pyfakefs.fake_filesystem_unittest.TestCase` base class.
The modules related to file handling are bound to the respective fake modules:
>>> os #doctest: +ELLIPSIS
>>> os.path #doctest: +ELLIPSIS
>>> shutil #doctest: +ELLIPSIS
`open()` is an alias for `io.open()` and is bound to `FakeIoModule.open`.
