I wrote the below code

    class Mixin(CreateBlockDeviceDatasetImplementationMixin, TestCase, ):
        def setUp(self):
            super(Mixin, self).setUp()
            if profiled_api:
                self.api = fakeprofiledloopbackblockdeviceapi_for_test(self, allocation_unit=LOOPBACK_ALLOCATION_UNIT)
            else:
                self.api = loopbackblockdeviceapi_for_test(self, allocation_unit=LOOPBACK_ALLOCATION_UNIT)
            self.mountroot = mountroot_for_test(self)
            self.deployer = BlockDeviceDeployer(node_uuid=uuid4(), hostname=u'192.0.2.10', block_device_api=self.api, mountroot=self.mountroot)
    return Mixin

What's a good function header?

Here's a good function header?
