Re: Test Driving WPF

Just because you can't unit test the gui doesn't mean you avoid testing the
gui.  You can't TDD yourself towards a good GUI.  But you can write
acceptance tests after the fact.  When I was working on a windows phone
app, what we did was create multiple projects.  One project was only the
xaml code.  The other project was all our code which could be unit tested.
(Ok, so technically it was 3 projects cause we had one with all the unit
tests)
