digitalmars.D.learn - Handling unittests that are designed to fail

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,

For the exceptions take a look here: http://dlang.org/phobos/std_exception.html#.assertThrown Bye, bearophile

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