Bug fixes in zc.buildout.testing
================================
Logging handler which did not get deleted
-----------------------------------------
The buildout testing set up runs a buildout which adds a
``logging.StreamHandler`` to the root logger. But tear down did not
remove it. This can disturb other tests of packages reusing
zc.buildout.testing.
The handers before calling set up are:
>>> import logging
>>> len(logging.getLogger().handlers)
1
>>> logging.getLogger().handlers # doctest: +ELLIPSIS
[<zope...testrunner.logsupport.NullHandler instance at ...>]
After calling it, a ``logging.StreamHandler`` was added:
>>> import zc.buildout.testing
>>> import doctest
>>> test = doctest.DocTestParser().get_doctest(
... '>>> x', {}, 'foo', 'foo.py', 0)
>>> zc.buildout.testing.buildoutSetUp(test)
>>> len(logging.getLogger().handlers)
2
>>> logging.getLogger().handlers # doctest: +ELLIPSIS +NORMALIZE_WHITESPACE
[<zope...testrunner.logsupport.NullHandler instance at ...>,
<logging.StreamHandler instance at ...>]
But tear down removes the new logging handler:
>>> zc.buildout.testing.buildoutTearDown(test)
>>> len(logging.getLogger().handlers)
1
>>> logging.getLogger().handlers # doctest: +ELLIPSIS
[<zope...testrunner.logsupport.NullHandler instance at ...>]
