"""This file contains unittests for the ipython1.frontend.cocoa.cocoa_frontend module.
|
|
|
|
|
|
Things that should be tested:
|
|
|
|
|
|
- IPythonCocoaController instantiates an IEngineInteractive
|
|
|
- IPythonCocoaController executes code on the engine
|
|
|
- IPythonCocoaController returns continuation for incomplete code
|
|
|
- IPythonCocoaController returns failure for exceptions raised in executed code
|
|
|
- IPythonCocoaController mirrors engine's user_ns
