Frameworks such as rspec support "Quiet" mocks which allow you to do one expectation per test. This (some would argue) gives a cleaner more BDD style test suite.
Basically the feature I'm after is a QuietMock object which verifies only the expectations that have been set and not the ones that haven't (stubbing them instead). To quote rspec's null_object (http://rspec.rubyforge.org/documentation/mocks/mocks.html):
it "instructs the mock to ignore (quietly consume) any messages it hasn’t been told to expect – and return itself".
Currently to achieve a one expectation per test you have to stub out all the behaviours you AREN'T testing which can become just as messy as the monolithic test.
Thanks in advance.
