test, test, test

Ok. Have managed (eventually) to get all the Unit tests to pass. That was a very illustrative experience and highlighted some issues - such as not getting all the associations completely nailed.
Funny how a quick "test" in the browser isn't really up to the job at all.
There are some issues with testing callbacks - doesn't seem anyway to pass information to and from the callback.

Now trying to crack the controller tests. The scaffold tests have, so far, failed in rather too many ways.

1) Failure:
test_should_create_brisque_set_up(BrisqueSetUpsControllerTest) [test/functional/brisque_set_ups_controller_test.rb:16]:
"BrisqueSetUp.count" didn't change by 1.
<3> expected but was
<2>.

2) Failure:
test_should_update_brisque_set_up(BrisqueSetUpsControllerTest) [test/functional/brisque_set_ups_controller_test.rb:35]:
Expected response to be a <:redirect>, but was <200>

Not quite sure why this should happen since this is an untouched-by-human-hands object.
We'll find out ...
