ArgumentMatchers are messages that you can include in message expectations to match arguments against a broader check than simple equality.
With the exception of any_args() and no_args(), the matchers are all positional - they match against the arg in the given position.
Passes if object receives :message with any args at all. This is really a more explicit variation of object.should_receive(:message)
Passes if the argument responds to the specified messages.
array = [] display = double('display') display.should_receive(:present_names).with(duck_type(:length, :each)) => passes
:call-seq:
object.should_receive(:message).with(hash_including(:key => val)) object.should_receive(:message).with(hash_including(:key)) object.should_receive(:message).with(hash_including(:key, :key2 => val2))
Passes if the argument is a hash that includes the specified key(s) or key/value pairs. If the hash includes other keys, it will still pass.
