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:', repr(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))
