"""The isolation plugin resets the contents of sys.modules after running
each test module or package. Use it by setting ``--with-isolation`` or the
NOSE_WITH_ISOLATION environment variable.

The effects are similar to wrapping the following functions around the
import and execution of each test module::

def setup(module):
        module._mods = sys.modules.copy()
    
    def teardown(module):
        to_del = [ m for m in sys.modules.keys() if m not in
                   module._mods ]
        for mod in to_del:
            del sys.modules[mod]
        sys.modules.update(module._mods)

Isolation works only during lazy loading. In normal use, this is only
during discovery of modules within a directory, where the process of
importing, loading tests and running tests from each module is
encapsulated in a single loadTestsFromName call. This plugin
implements loadTestsFromNames to force the same lazy-loading there,
which allows isolation to work in directed mode as well as discovery,
at the cost of some efficiency: lazy-loading names forces full context
setup and teardown to run for each name, defeating the grouping that
is normally used to ensure that context setup and teardown are run the
fewest possible times for a given set of names.

.. warning ::

This plugin should not be used in conjunction with other plugins
    that assume that modules, once imported, will stay imported; for
    instance, it may cause very odd results when used with the coverage
    plugin.
