Question

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]
public ActionResult CheckOut(Cart cart, ShippingDetails shippingDetails, CreditCard creditCard)
{
// Empty carts can't be checked out
if (cart.Lines.Count == 0)
    ModelState.AddModelError("Cart", "Sorry, your cart is empty!");

// Everything is valid
if (ModelState.IsValid)
{
    // Effectue le paiement.
    TransactionResult result = creditcardProcessor.TakePayment(creditCard, cart.ComputeTotalValue());
    if (result == TransactionResult.Success)
    {
        // Envoi la commande
        orderSubmitter.SubmitOrder(cart, shippingDetails);
        cart.Clear();
        return View("Completed");
    }
    else
    {
        ModelState.AddModelError("CreditCard", "Sorry, we couldn't process your credit card, please verify your credit card details and retry.");
        return View(new CheckOutViewModel());
    }

}
else // Something was invalid
    return View(new CheckOutViewModel());
}

public class MainCreditCardProcessor : ICreditCardProcessor
{
    public TransactionResult TakePayment(CreditCard card, decimal amount)
    {
        if (card.SecurityCode == "test")
            return TransactionResult.Success;
        else
            return TransactionResult.TransactionDeclined;
    }
}

找到解决方案。模拟对象没有任何实现。（在此之前我应该知道）

为什么这个测试单元通过？
