tests = code and lots of it More tests always means The gift card class for Starbuzz has four attributes, so we’re going to need several tests to exercise those attributes. We could test for: 302 Chapter 8 A gift card with more than enough to cover the cost of the order A gift card without enough to cover the cost of the order An invalid gift card number A gift card with exactly the right amount A gift card that hasn’t been activated A gift card that’s expired lots more code And that’s just for the gift cards. You’ll need tests for variations on the OrderInformation class, too...and we still haven’t tested for the bigger failure cases, like what happens if the database fails to save an order. These are really important things to test, but not only are we going to have to write tests for these cases, we’re going to have to write up a bunch of strategies too... Automated test-driven development means a LOT of test code. The more functionality you have, the more tests you’ll need. And more tests means more code... lots and lots of code. But all that code also means a lot more stability. You’ll know your system is working, at every step of the way. And sometimes, you may not need quite as much code as you first thought... Download at WoweBook.Com In each case, we need a gift card object with a slightly different set of values, so we can test each variation in our order processing class.
Strategy patterns, loose couplings, object stand ins... Suppose we used the strategy pattern again for all the different variations on the types of gift card a database could return, like this: Here’s a strategy that will make good gift cards... TestGoodDBAccessor + getGC(gcId : int) :GiftCard + saveGC(card : GiftCard) :void DBAccessor + getGC(gcId : int) :GiftCard + saveGC(card : GiftCard) :void TestInsufficientDBAccessor + getGC(gcId : int) :GiftCard + saveGC(card : GiftCard) :void Here’s one that will make a gift card with To avoid all these extra classes, you could have one TestDBAccessor implementation that returned different cards based on the ID you gave it, but that’s screwing up loose coupling. TestDBAccessor would have to be in sync with your test code to make sure they agree on what each ID means. TestInvalidDBAccessor + getGC(gcId : int) :GiftCard + saveGC(card : GiftCard) :void test-driven development MySQLDBAccessor + getGC(gcId : int) :GiftCard + saveGC(card : GiftCard) :void insufficient funds on it.Here’s one that will throw But each test gift card accessor shares a lot of code, and that’s bad, too...so what do we do? Download at WoweBook.Com Here’s the real MySQL accessor. an error regardless of what ID you give it. you are here 4 303
