測試驅(qū)動開發(fā)

1、測試驅(qū)動開發(fā)Test-driven development想到了什么.軟件質(zhì)量外部質(zhì)量內(nèi)部質(zhì)量設(shè)計開發(fā)有效率TDD是什么涉及UI的測試功能測試單元測試TDD是什么與極限編程提出的測試先行有關(guān)聯(lián)是一種軟件研發(fā)過程，開發(fā)風格可以做到簡單設(shè)計、增強信心TDD-軟件開發(fā)過程增加一個測試運行所有的測試，觀察新建的測試是失敗的針對新建測試寫實現(xiàn)代碼運行所有的測試成功重構(gòu)代碼TDD涉及的概念test doubledummyfakestubmock一個測試依據(jù)一份訂單，出貨威士忌產(chǎn)品 訂單包含一種產(chǎn)品和這個產(chǎn)品的出貨數(shù)量，倉庫有不同的產(chǎn)品庫存。如倉庫中有足夠的產(chǎn)品則出貨，該產(chǎn)品在倉庫中的總量減少出貨數(shù)；如倉庫

2、中沒有足夠的產(chǎn)品，該產(chǎn)品不出貨。訂單 order；倉庫 warehouse；產(chǎn)品 product；產(chǎn)品清單 inventorypublic class OrderStateTest private static String TALISKER = “Talisker”;private static String HIGHLAND_PARK = Highland Park;private Warehouse warehouse = new WarehouseImpl();protected void setUp() warehouse.add(TALISKER, 50);warehouse.ad

5、LIDATIONassertTrue(order.isFilled();assertTrue(0, warehouse.getInventory(TALISKER);assertFalse(order.isFilled();assertEquals(50, warehouse.getInventory(TALISKER);清理-CLEANUP這個示例中，沒有顯示地恢復測試前狀態(tài)。由垃圾回收器回收對象，恢復測試前狀態(tài)public class OrderStateTest private static String TALISKER = “Talisker”;private static Stri
