I can't comment on lift since we use scala with WebWork/struts2. Testing with specs and mockit has been much easier for us than in the bad ole Java days. val m = mock[java.util.List[String]] // a concrete class would be mocked with: mock(new java.util.LinkedList[String]) // stub a method call with a return value m.get(0) returns "one" // call the method m.get(0) // verify that the call happened, this is an expectation which will throw a FailureException if that is not the case m.get(0) was called // we can also check that another call did not occur m.get(1) wasnt called // or m.get(1) was notCalled http://code.google.com/p/specs/wiki/UsingMockito http://code.google.com/p/specs/wiki/UsingMockito Being able to write a test like this seems like a pretty big win. re: newcomer-unfriendly, the people I've spoken with all seem really excited about the language and want to share the love. shrug
