Perhaps it goes without saying, but I was not aware of that ;)
As you noted earlier this thread (not quoted above) RSpec::Mocks::Mock
instances (returned by double(), mock(), or stub()) are strict by
default - e.g. they'll complain about any unexpected messages.
Obviously that does not account for any real objects.
I'm open to adding an API for this, but not
object.should_receive(:nothing) since that syntax is for declaring
Other ideas welcome.
