Hi all,

I'd like to design a unittest that will fail -- that is, it will trigger an
assert() or enforce() failure inside the function it is testing.

How would I go about doing this so that the unittest {} block will confirm the failure and count this as a "pass"?

Thanks & best wishes,

assertThrown and maybe collectException

For the exceptions take a look here:

Bye,

Thanks to both of you :-)  In the end I decided to go with collectExceptionMsg as this allows a very precise unittest.
