I am a bit new to mocking. I am trying to stub the
ActiveMerchant::Billing::PaypalGateway#authorize method but not clear how to
do it. This is my code and spec.
This is the pertinent code:
module Payment
def gateway
ActiveMerchant::Billing::PaypalGateway.new(
...
)
end
def authorize_payment(payment_info, associated_record_type,
associated_record_id)
gateway.authorize(payment_info.amount ......
end
I tried this:
ActiveMerchant::Billing::PaypalGateway.should_receive(:authorize).and_return(authorize_payment_success_response)
And it does work on its own, but when I call Payment.gateway.authorize,
ActiveMerchant still goes out to the web. I perhaps am missing understanding
something -- yes, calling gateway.authorize does create a new
ActiveMerchant::Billing::PaypalGateway, but I thought by stubbing the class
I should be ok.
Or alternatively is there a way I can do something like:
Payment.gateway.authorize.should_receive(:authorize).and_return(nil)
I am guessing this question does not have to specifically do with
ActiveMerchant but how to mock and stub through cascading levels of
classes/objects.
