matching without using the rest of rspec-mocks.
enables 3rd party mocking libs to take advantage of rspec’s argument
Can also be used directly to match the contents of any ‘Array`. This
expect(object).to receive(:message).with(hash_including(:a => ’b’))
match against the real objects .e.g.
Values passed to ‘with` can be literal values or argument matchers that
object.message(:a, ’b’, 3)
expect(object).to receive(:message).with(:a, ‘b’, 3)
the ‘with` method on a `MessageExpectation`:
Wrapper for matching arguments against a list of expected values. Used by
