"""

Start a :func:`pdb.post_mortem` on errors and failures.
|
|
|
|
This plugin implements :func:`testOutcome` and will drop into pdb
|
|
whenever it sees a test outcome that includes exc_info.
|
|
|
|
It fires :func:`beforeInteraction` before launching pdb and
|
|
:func:`afterInteraction` after. Other plugins may implement
|
|
:func:`beforeInteraction` to return False and set event.handled to
|
|
prevent this plugin from launching pdb.
