Function MockEventNotification

python/ycm/tests/event_notification_test.py:58–85

Mock out the EventNotification client request object, replacing the Response handler's JsonFromFuture with the supplied |response_method|. Additionally mock out YouCompleteMe's FiletypeCompleterExistsForFiletype method to return the supplied |native_filetype_completer| parameter, rather than

( response_method, native_filetype_completer = True )
