IPython/kernel/tests/test_engineservice.py

# encoding: utf-8

"""This file contains unittests for the kernel.engineservice.py module.

Things that should be tested:

 - Should the EngineService return Deferred objects?
 - Run the same tests that are run in shell.py.
 - Make sure that the Interface is really implemented.
 - The startService and stopService methods.
