python3-pytest-mock binary package in Ubuntu Oracular amd64

 This plugin installs a "mocker" fixture which is a thin wrapper
 around the patching API provided by the excellent "mock" package or
 by unittest.mock, but with the benefit of not having to worry about
 undoing patches at the end of a test. It also provides other nice
 utilities such as spy and stub, and uses pytest introspection when
 comparing calls.
 .
 This package provides the Python 3 module.
