Wrapper for matching arguments against a list of expected values. Used by the `with` method on a `MessageExpectation`:
expect(object).to receive(:message).with(:a, 'b', 3) object.message(:a, 'b', 3)
Values passed to `with` can be literal values or argument matchers that match against the real objects .e.g.
expect(object).to receive(:message).with(hash_including(:a => 'b'))
Can also be used directly to match the contents of any `Array`. This enables 3rd party mocking libs to take advantage of rspec's argument matching without using the rest of rspec-mocks.
require 'rspec/mocks/argument_list_matcher' include RSpec::Mocks::ArgumentMatchers arg_list_matcher = RSpec::Mocks::ArgumentListMatcher.new(123, hash_including(:a => 'b')) arg_list_matcher.args_match?(123, :a => 'b')
This class is immutable.

@api public @param [Array] args
Matches each element in the `expected_args` against the element in the same position of the arguments passed to `new`.
