No. If you want a "real" DomainObjectContainer, then (as Oscar suggests)
write an integration test rather than a unit test.

That's not quite what the error message says. It says that it's not
invoked with the particular QueryDefault parameter you specified
("parameter 0 did not match"). You should use a Hamcrest matcher in your
expectation:
oneOf(mockContainer).firstMatch(with(queryDefaultMatching(MOrganisation.class,
"fetch_orgnaisation_by_id", "orgId", consumptionProfile.getSiteId()));
where "queryDefaultMatching(..)" returns an instance of
Matcher<QueryDefault>.
That said, this awkwardness is because the ExcelSheet is probably doing too
much. I'd change your design by introducing an OrganisationRepository, and
inject that into ExcelSheet. Then you can write a much simpler test that
mocks out OrganisationRepository rather than DomainObjectContainer. Then
write a separate unit (or perhaps better: integration) test for
OrganisationRepository.

The "JunitMockery" framework is just a few helper classes around the JMock
library [1]. The difficulties you are having are with JMock expectations;
so check out the JMock documentation, which is pretty good. It's a
worthwhile investment learning how to mock.
