def test_lineendings(): r"""
*nix systems use \n line endings, while Windows systems use \r\n.  Python
handles this using universal newline mode for reading files.  Let's make
sure doctest does so (issue 8473) by creating temporary test files using each
of the two line disciplines.  One of the two will be the "wrong" one for the
platform the test is run on.

Windows line endings first:

    >>> import tempfile, os
    >>> fn = tempfile.mktemp()
    >>> with open(fn, 'wb') as f:
    ...     f.write('Test:\r\n\r\n  >>> x = 1 + 1\r\n\r\nDone.\r\n')
    >>> doctest.testfile(fn, module_relative=False, verbose=False)
    TestResults(failed=0, attempted=1)
    >>> os.remove(fn)

And now *nix line endings:

    >>> fn = tempfile.mktemp()
    >>> with open(fn, 'wb') as f:
    ...     f.write('Test:\n\n  >>> x = 1 + 1\n\nDone.\n')
    >>> doctest.testfile(fn, module_relative=False, verbose=False)
    TestResults(failed=0, attempted=1)
    >>> os.remove(fn)
