我在这上花了2个多小时...我无法弄清楚为什么这个测试正在通过。我的意思是..它不应该返回视图“已完成”,但在测试中它确实如此!它说预期“string.Empty”但返回“已完成”但是对于信用卡要通过..安全码需要是“测试”,这在测试中根本不存在。所以它应该返回默认视图(类似于view();)。
我做错了什么?这是我的测试错了吗?还是控制器逻辑?
非常感谢。
[Test]
public void Cannot_Check_Out_If_Credit_Card_Failed_To_Process()
{
var mockOrderSubmitter = new Mock<IOrderSubmitter>();
var mockCreditCardProcessor = new Mock<ICreditCardProcessor>();
// Arrange: Given a user has a non-empty cart
var cart = new Cart();
cart.AddItem(new Product(), 1);
// Arrange: ... but the credit card failed to process
var cartController = new CartController(null, mockOrderSubmitter.Object, mockCreditCardProcessor.Object);
var result = cartController.CheckOut(cart, new ShippingDetails(), new CreditCard() { SecurityCode = "123" });
// Assert
result.ShouldBeDefaultView();
}
[HttpPost]

我找到了解决问题的方法。为了帮助其他可能有相同问题的人,我将解释它。
问题在于我的测试。由于mocks对象是没有方法的空对象,所以零逻辑。这意味着测试实际上不使用MainCreditCarDProcessor的实例。 (我不知道那个)
所以我必须通过添加:
来为这个特定的测试设置模拟// Arrange: Given we have a creditcard processor that return TransactionDeclined.
mockCreditCardProcessor.SetReturnsDefault(TransactionResult.TransactionDeclined);
要强制它返回TransactionDeclined,通过这不是“强制”,因为它是一个模拟你只是将它设置为返回该值,否则我猜它会返回它找到的默认值..在这种情况下是0枚举的第一个元素,或者返回其他类型的方法的null。
如果我说错了,请纠正我。
感谢。

如果ShouldBeDefaultView()
抛出,测试将失败。
