Someone else may have a more elegant approach, but the block syntax to
should_receive() could allow something like:
expected_message = Message.new(msg_creation_params)
SantasMailbox.should_receive(:deliver_secret_santa) do |msg|
msg.body.should == expected_message.body
msg.subject.should == expected_message.subject
# etc. if it's necessary
end
Message.create(msg_creation_params)
Feels clunky, though.
