[mocha-developer] More flexible return values?

Thanks for the great library, we use Mocha extensibly on our test and
love its readability and no-nonsense-ness.
One thing that would
be great, but that seems to be against some of the testing philosophy (which we
don't quite deeply understand yet, so we can't come up with kosher alternatives)
is the ability to be more flexible with the return values.
Presently the only
flexibility is to pass a Proc, but even this is going away. Ideally you could be
as flexible as passing a block that received the call's parameters (which the
Proc presently doesn't receive) so arbitrary logic could be
Knowing that the
more specific tests are the better, this flexibility allows for tests to be less
brittle. More concretely, in our case we are using Mocha to mock and stub calls
to a remote server. The code under test batches the calls for efficiency so that
the exact request parameters are not known on each invokation, and the
particular test wants to be independent of the batching parameters.
might be that the number of possible return values is large given the inputs and
can be expressed more succintly as a simple formula on the paramteters. Or the
input and output must be ordered data but the order is not known or arbitrarily
set by an intermediate component (e.g. a database).
Or is there some
other way that we are missing? thanks for elucidating us and for the great work
on this library.
