def test_DocTestParser(): r"""
Unit tests for the `DocTestParser` class.

DocTestParser is used to parse docstrings containing doctest examples.

The `parse` method divides a docstring into examples and intervening
text:

    >>> s = '''
    ...     >>> x, y = 2, 3  # no output expected
    ...     >>> if 1:
    ...     ...     print x
    ...     ...     print y
    ...     2
    ...     3
    ...
    ...     Some text.
    ...     >>> x+y
    ...     5
    ...     '''
    >>> parser = doctest.DocTestParser()
    >>> for piece in parser.parse(s):
    ...     if isinstance(piece, doctest.Example):
    ...         print 'Example:', (piece.source, piece.want, piece.lineno)
    ...     else:
    ...         print '   Text:', `piece`
       Text: '\n'
    Example: ('x, y = 2, 3  # no output expected\n', '', 1)
       Text: ''
    Example: ('if 1:\n    print x\n    print y\n', '2\n3\n', 2)
       Text: '\nSome text.\n'
    Example: ('x+y\n', '5\n', 9)
       Text: ''

The `get_examples` method returns just the examples:

    >>> for piece in parser.get_examples(s):
    ...     print (piece.source, piece.want, piece.lineno)
    ('x, y = 2, 3  # no output expected\n', '', 1)
    ('if 1:\n    print x\n    print y\n', '2\n3\n', 2)
    ('x+y\n', '5\n', 9)

The `get_doctest` method creates a Test from the examples, along with the
given arguments:

    >>> test = parser.get_doctest(s, {}, 'name', 'filename', lineno=5)
    >>> (test.name, test.filename, test.lineno)
    ('name', 'filename', 5)
    >>> for piece in test.examples:
    ...     print (piece.source, piece.want, piece.lineno)
    ('x, y = 2, 3  # no output expected\n', '', 1)
    ('if 1:\n    print x\n    print y\n', '2\n3\n', 2)
