# Testing UIFactories is a bit interesting because we require they all support a
 
20
# common interface, but the way they implement it can vary very widely.  Between
 
21
# text, batch-mode, graphical and other potential UIFactories, the requirements
 
22
# to set up a factory, to make it respond to requests, and to simulate user
 
23
# input can vary a lot.
 
24
#
 
25
# We want tests that therefore allow for the evaluation of the result to vary
 
26
# per implementation, but we want to check that the supported facilities are
 
27
# the same across all UIFactorys, unless they're specifically skipped.
 
28
#
 
29
# Our normal approach is to use test scenarios but that seems to just end up
 
30
# creating test-like objects inside the scenario.  Therefore we fall back to
 
31
# the older method of putting the common tests in a mixin.
 
32
#
 
33
# Plugins that add new UIFactorys can create their own subclasses.
