Test the :py:class`pyfakefs.example` module to demonstrate the usage of the
:py:class`pyfakefs.fake_filesystem_unittest.TestCase` base class.
Fake filesystem functions like `create_file()`, `create_dir()` or
`create_symlink()` are often used to set up file structures at the beginning
of a test.
While you could also use the familiar `open()`, `os.mkdirs()` and similar
functions, these functions can make the test code shorter and more readable.
`create_file()` is particularly convenient because it creates all parent
directories and allows you to specify the contents or the size of the file.

The os and shutil modules have been replaced with the fake modules,
so that all of the calls to os and shutil in the tested example code
occur in the fake filesystem.

`self.setUp()` method. This defines:
* Attribute `self.fs`, an instance of
:py:class:`pyfakefs.fake_filesystem.FakeFilesystem`. This is useful
for creating test files.
* Attribute `self.stubs`, an instance of
:py:class:`pyfakefs.mox3_stubout.StubOutForTesting`. Use this if
you need to define additional stubs.
