If you have many patches to apply and you want them to apply to things initialised in the setUp methods too try this:

def setUp(self):
    self.patches = {
        "sut.BaseTestRunner._acquire_slot": mock.Mock(),
        "sut.GetResource": mock.Mock(spec=GetResource),
        "sut.models": mock.Mock(spec=models),
        "sut.DbApi": make_db_api_mock()
    }

    self.applied_patches = [mock.patch(patch, data) for patch, data in self.patches.items()]
    [patch.apply for patch in self.applied_patches]
    .
    . rest of setup
    .


def tearDown(self):
    patch.stopall()
