Question

虽然嘲笑我遇到了一些问题。

 private Mock<IPaymentHandler> _mockRecurringPaymentHandler;
 private Mock<IPaymentHandler> _mockRecurringPaymentFailedHandler;
 private IEnumerable<IPaymentHandler> _paymentManagers;

_mockRecurringPaymentHandler = new Mock<IPaymentHandler>();
_mockRecurringPaymentFailedHandler = new Mock<IPaymentHandler>();

_paymentManagers = new List<IPaymentHandler>
{
    _mockRecurringPaymentHandler.Object,
    _mockRecurringPaymentFailedHandler.Object
};

_sut = new PaypaIIpnManager(
    _paymentManagers,
    _mockLogger.Object
    );

最近我尝试为mockRecurringPaymentHandler设置方法，例如：

_mockRecurringPaymentHandler.Setup(method => method.GetPaymentType()).Returns("GFDGDFGDFG");

它不起作用。它只有在我将它传递给列表之前才能工作。为什么会出现这种行为？

public PaypaIIpnManager(
            IEnumerable<IPaymentHandler> paymentHandlers,
            ILoggerService<PaypaIIpnManager> logger)
        {
            _handlersDic = RegisterStrategy(paymentHandlers);
            _logger = logger;
        }

protected Dictionary<string, IPaymentHandler> RegisterStrategy(IEnumerable<IPaymentHandler> paymentHandlers)
        {
            var dic = new Dictionary<string, IPaymentHandler>();

            foreach (var handler in paymentHandlers)
            {
                var paymentType = handler.GetPaymentType();

                dic.Add(paymentType, handler);
            }

            return dic;
        }

记住单元测试适用于AAA的概念--- Arrange，Act和Assert。在你没有妥善安排事情之前，行为不能按要求行事。

因此，在调用PaypaIIpnManager构造函数时，它会调用您的RegisterStrategy，为您的模拟处理程序调用{{1}}。从调用构造函数之前，GetPaymentType未设置为什么在测试中未调用设置方法GetPaymentType。所以在这里，您应该在调用构造函数之前定义GetPaymentType安装程序。
