ArgumentMatchers are placeholders 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`, they all match against the arg in same position in the argument list.
Passes if object receives `:message` with any args at all. This is really a more explicit variation of `object.should_receive(:message)`
@example
object.should_receive(:message).with(any_args())
Passes if the argument responds to the specified messages.
@example
object.should_receive(:message).with(duck_type(:hello)) object.should_receive(:message).with(duck_type(:hello, :goodbye))
Passes if the argument is a hash that doesn‘t include the specified key(s) or key/value
@example
object.should_receive(:message).with(hash_excluding(:key => val)) object.should_receive(:message).with(hash_excluding(:key)) object.should_receive(:message).with(hash_excluding(: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.
@example
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))
