[mocha-developer] expects with returns that returns the return value of the actual method

[Steve Eichert]

I'm trying to test some code that's using active_merchant using the
following test.  What I'd like to be able to do is verify that purchase is
called, however, rather than specifying the return value for purchase with
returns, I'd like it to return the actual return value provided if you
called the non mocked purchase method.  Is this possible?

def test_charge
    gateway = ActiveMerchant::Billing::Base.gateway(:bogus).new
    ActiveMerchant::Billing::Base.mode = :test

    member = Member.new
    member.credit_card_number = "1"
    member.expiration_date = "9/19/2007"
    member.payment_method = "bogus"
    member.first_name = "Steve"
    member.last_name = "Eichert"
    member.expects(:active_merchant_gateway).returns(gateway)

    # gateway.expects(:purchase).returns(:non_mocked_return)

    member.charge

    assert member.paid
end
