http://d.puremagic.com/issues/show_bug.cgi?id=10026 Summary: Allow to assert that exception must be thrown Product: D Version: future Platform: All OS/Version: All Status: NEW Severity: enhancement Priority: P2 Component: druntime AssignedTo: nobody@puremagic.com ReportedBy: stpasha@gmail.com --- Comment #0 from Pasha S <stpasha@gmail.com> 2013-05-03 18:55:02 PDT --- I'd like to suggest that existing syntax for assert() keyword was enhanced in order to allow detection of exception thrown by the expression provided. It may look like this: assert!(DivisionByZero)( powermod(2, 1000, 0) ); assert!(InvalidArgument)( fastsqrt(-42) ); (or it may look otherwise, I'm not really an expert in language syntax). The reason for such functionality to exist is that "assert" is used for unit-testing of a class or module. Correct handling of errors is part of the specification of any non-trivial class, and the "D way" to handle errors is by throwing exceptions. Which current assert cannot test. What do you think? -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- |
