Source code for nose2.plugins.loader.functions
"""
Load tests from test functions in modules.
This plugin responds to :func:`loadTestsFromModule` by adding test
cases for all test functions in the module to ``event.extraTests``. It
uses ``session.testMethodPrefix`` to find test functions.
Functions that are generators, have param lists, or take arguments
are not collected.
This plugin also implements :func:`loadTestsFromName` to enable loading
tests from dotted function names passed on the command line.
