Since r69 of OCMock, it’s possible to reject a method call http://svn.mulle-kybernetik.com/OCMock/trunk/Source/Changes.txt
Nice mocks / failing fast When a
method is called on a mock object that
has not been set up with either expect
or stub the mock object will raise an
exception. This fail-fast mode can be
turned off by creating a “nice” mock:id mock = [OCMockObject niceMockForClass:[SomeClass class]]While nice mocks will simply ignore
all unexpected methods it is possible
to disallow specific methods:[[mock reject] someMethod]Note that in fail-fast mode, if the
exception is ignored, it will be
rethrown when verify is called. This
makes it possible to ensure that
unwanted invocations from
notifications etc. can be detected.
