Mocks are interesting, but verifying that methods were called on the mock seems like testing side effects rather than behavior.

@sgrif not really, imo. You pass in a substitute to the test subject, which is entirely oblivious as to whether it hits a payment gateway.
@realntl Same with a test double (aka a mock)? You're passing in a fake object to stand in for the real one, and asserting the side effect

@sgrif but what are you testing? I want to pass in a payment processor that declines every card, and assert that I don't complete the order. -
@sgrif the contract of the payment processor is irrelevant, which is the only thing a mock can assert on, right? (I could be crazy here) - 3 more replies
