Negative acceptance testing

| Has anyone out there had to run any negative acceptance testing using
XP methodology? We have a large applcication with few interfaces,
however, we are looking into testing fail cases using fit.
Anyone have any experiences or advise they can offer?
Are your acceptance tests all positive test scenarios?
Regards

I have some difficulty figuring out why you would want
a negative scenario if you're doing development. That is,
you should be able to create the corresponding positive
scenario.
On the other hand, if you're writing tests for existing
defects, there's a lot to be said for negative scenarios.
They're called regression tests, and sometimes it's
politically necessary to be able to demonstrate that the
new release doesn't do whatever it used to do, and
that the bug doesn't resurect itself.
As far as FIT is concerned, look at the fat.table
and fat.color fixtures. They are there to isolate
tables that create failures and then check whether
the correct number of cells had failures. Whether
that suits what you need is debatable, but it should
give you some ideas about how to proceed.
