Subject: Exceptions inside assertions
Date: Wed, 10 Nov 1999 01:06:57 +0100 [thread overview]
Message-ID: <99111001200402.23873@ice> (raw)
Hi,
I have a problem with exceptions which are raised within the expression of an
assertion, e.g.
assert (raise Not_found)
The current behaviour is that the exception "falls through the assertion" which
may not be appropriate for some cases. For example, consider
assert (Queue.peek queue == current_element)
>From my point of view, the assertion expresses that "queue" has at least one
element and that this element is identical to "current_element". But if the
assertion is violated because the queue is empty, I only get a Queue.Empty
exception, and I do not see the reason for it. Perhaps I even catch
Queue.Empty, and the program continues, which is very hard to find out.
I suggest to introduce a new Assert_failure_by_exception exception to better
report this situation.
Gerd
