Officially, no. However we're in mid-stream towards supporting
something like this for 0.9 (currently available as a beta gem from .
Basically, anything you can say after "should " or "should_not " you
can pass to #with on a mock. So, in this case, because you can say:

obj.should be_an_instance_of(Proc)

you can also say:

m.should_receive( :test_method ).with(be_an_instance_of(Proc))

We haven't worked out the details of how we'll support this using
different names just yet, so for now you have to either use this
basically un-readable option (that works) or wrap it yourself in
something more pleasant.

Sooner or later we'll support this officially w/ nicer, more readable names.

Hope this helps in the mean time.

Cheers,
David
