Limitations: - When generating examples for use as doctests, make sure that you have pretty-printing OFF. This can be done either by setting the ``PlainTextFormatter.pprint`` option in your configuration file to False, or by interactively disabling it with %Pprint. This is required so that IPython output matches that of normal Python, which is used by doctest for internal execution. - Do not rely on specific prompt numbers for results (such as using '_34==True', for example). For IPython tests run via an external process the prompt numbers may be different, and IPython tests run as normal python code won't even have these special _NN variables set at all. � N)� modified_envc s e Zd Z� fdd�Z� ZS )� DocTestFinderc sH t � �|||||�}tt|dd��rD|d urD|jD ]}d|jtj< q2|S )NZ__skip_doctest__FT)�super� _get_test�bool�getattrZexamples�options�doctest�SKIP)�self�obj�name�module�globs� source_lines�test�example�� __class__� ��/root/rpmbuild/BUILDROOT/imh-python39-modules-3.9.7-92.el8.x86_64/opt/imh-python/lib/python3.9/site-packages/IPython/testing/plugin/ipdoctest.pyr ) s zDocTestFinder._get_test)�__name__� __module__� __qualname__r � __classcell__r r r r r ( s r c @ s" e Zd ZdZe�d�Zdd� ZdS )�IPDoctestOutputCheckerz�Second-chance checker with support for random tests.
