Hi Olivier, that should indeed be the behavior, but the test also passes if I remove the throw Error() line in my Account constructor. This is probably because the fail() in the testcase is directly caught by the catch block underneath. I used to do it this way in AS2, but it seems like the try/catch behavior is different in AS3.
Does anyone have any solution for this, or another way of testing throw statements? regards, Christophe --- In flexcoders@yahoogroups.com, "Stembert Olivier (BIL)" <[EMAIL PROTECTED]> wrote: > > Hi Christophe, > > It seems logic the fail() statement is not executed since it follows the > new Account() statement which throws the exception. > I'm not sure I understand what you mean... > > Regards, > > Olivier > > ________________________________ > > From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On > Behalf Of herrodius > Sent: Wednesday, January 17, 2007 11:53 AM > To: flexcoders@yahoogroups.com > Subject: [flexcoders] [Flexunit] - How to test throwing errors? > > > > Hi all, > > sorry for this slightly OT message. > > I was wondering what the best way is to test for a method throwing an > error.
