try add flash.net.registerClassAlias( "attempt.TestInterface", TestInterface ); prior to your cast attempt.

lus I see a number of places on the web where the idea is mentioned, e.g. http://www.herrodius.com/blog/?m=200704 . However I cannot find any mock frameworks for AS3. This evening I spent some time trying to mock one up on my own (ok, sorry for the pun!) but I ran into troubles. Is anyone interested in thinking about this problem with me? Here is what I did during my 20 minutes of playing: Define an interface: public interface TestInterface { function setSomething(something : String) : void; } Run the following code: public function flexmock() { var i : TestInterface; var c : Class = flash.utils.getDefinitionByName("attempt.TestInterface") as Class; var desc : XML = flash.utils.describeType(c); var str : String = desc.toString(); var a : Object = new Object(); a["setSomething"] = function(something : String) : void { trace(something); }; // will fail on the following line, since a does not implement TestInterface. i = TestInterface(a); i.setSomething("blah"); } AS3 doesn't support duck typing like Ruby, and I believe there is no way to get an object in memory that implements the TestInterface interface that my other objects can use as a mock. Any thoughts about this? Am I doomed to use elbow grease or code generation to create these things? BTW, this message is also posted on the ActionScript 3 FlexUnit Library forum in Google Groups. Hopefully that isn't some kind of forum faux pas. Thank you for any comments, Adam
