#176 scriptable tests

[Chris Roeder]

I ran the test-target in build.xml and saw that errors raise dialogs limiting the scriptability of them.
In cases where the test is of functionality that is on the model, not the view, the tests should not
raise dialogs in case of error. Where the view is being tested, a testing framework should be
used that can deal with these.

...and yes, as time allows, I'm volunteeting.
