Hey Dan,
I've just taken a look at this. Could you send a PR with just the UITestHarness based test against the angular-addon project? AFAIK the addon currently lacks UITestHarness based tests.
Note that I intend to have a minimal number of UITestHarness based tests, since I would be using the UITestHarness purely for ensuring the wizards work, and not for testing the structure of the generated scaffold. On a more broader perspective, I'm looking at re-introducing the webtest harness in Forge, and tests based on those in the angular addon (these would be ported from the F1 plugin).
