RE: Ignoring all mock method calls EXCEPT certain ones

by Lawson, Robert W :: Rate this Message:

Nat, I really appreciate the fact that you took the time to respond in detail. Thanks!! Just curious, is the reason you never found a need for this because you confirm in your tests every call made by the object-under-test to the mock? Our situation is that we are mocking UI objects that get called from a controller (as in model-view-controller). Because it is user-interface intensive, there are often a lot of calls made to the mocks. Some of the calls are more important than others in verifying that the object-under-test is behaving as it should. Hence our desire to selectively set expectations.

Also, do you use jMock to test anonymous classes? If so, how do you do that?

Sorry about the lack of detail in my last mail. I sent it from my
iPhone and it's not easy to write lots of text.

The following link describes how jMock dispatches a method calls to
expectations and explains why oneOf and allowing don't interact how
you expect.

http://www.jmock.org/dispatch.html

The following link explains how you can use Matchers to specify which
mock objects and methods match an expectation. You can use that to
match all methods of a mock object except those you've already
specified expectations for.

http://www.jmock.org/match-object-or-method.html

It's not ideal: jMock could perhaps have an API call to let a test
easily specify "all other methods of object o". It's not something
that I've ever found a need for in practice so I've never considered
it. I'll have a think about how it could be implemented.
