Hi Christophe, Sorry for my late response. You can use the following syntax to signal an error in response to an incoming message:
protocol describe once: mock recv: #msg; signals: Error. Note that the Error is a class not an instance. Or alternatively you can execute an arbitrary block like Guillaume suggested. protocol describe once: mock recv: #msg; => [ Error signal: 'asdf' ]. -- View this message in context: http://forum.world.st/ANN-BabyMock-2-tp4748530p4755157.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.
