1 Bug fixes in zc.buildout.testing

     2 ================================

     3 

     4 Logging handler which did not get deleted

     5 -----------------------------------------

     6 

     7 The buildout testing set up runs a buildout which adds a

     8 ``logging.StreamHandler`` to the root logger. But tear down did not

     9 remove it. This can disturb other tests of packages reusing

    10 zc.buildout.testing.

    11 

    12 The handers before calling set up are:

    13 

    14     >>> import logging

    15     >>> len(logging.getLogger().handlers)

    16     1

    17     >>> logging.getLogger().handlers # doctest: +ELLIPSIS

    18     [<zope...testrunner.logsupport.NullHandler instance at ...>]

    19 

    20 After calling it, a ``logging.StreamHandler`` was added:

    21 

    22     >>> import zc.buildout.testing

    23     >>> import doctest

    24     >>> test = doctest.DocTestParser().get_doctest(

    25     ...     '>>> x', {}, 'foo', 'foo.py', 0)

    26     >>> zc.buildout.testing.buildoutSetUp(test)

    27     >>> len(logging.getLogger().handlers)

    28     2

    29     >>> logging.getLogger().handlers # doctest: +ELLIPSIS +NORMALIZE_WHITESPACE

    30     [<zope...testrunner.logsupport.NullHandler instance at ...>,

    31      <logging.StreamHandler instance at ...>]

    32 

    33 But tear down removes the new logging handler:

    34 

    35     >>> zc.buildout.testing.buildoutTearDown(test)

    36     >>> len(logging.getLogger().handlers)

    37     1

    38     >>> logging.getLogger().handlers # doctest: +ELLIPSIS

    39     [<zope...testrunner.logsupport.NullHandler instance at ...>]
