Question

我目前正在编写一个失败的单元测试...它说明：failed. Expected:<0>. Actual:<16>.我明白这是因为RateManagement模型未正确设置，但是不确定如何在我的测试中设置这些数据。

问题：如何填充RateManagement模型以便我可以正确测试值？

测试失败

[TestMethod]
public void BabysitterBusiness_StartTimeBedTimeAndEndTimeAreRecorded_ReturnsCorrectAmountDue()
{
    // Arrange
    var data = new RateManagement
    {
        TotalBedtimeHours = TimeSpan.FromHours(3),
        TotalHoursBeforeBedtime = TimeSpan.FromHours(2),
        TotalOvertimeHours = TimeSpan.FromHours(4)
    };

    // Act
    var result = _business.CalculatePaymentDue();

    // Assert
    Assert.AreEqual(result, 16M);
}

RateManagement Class

public class RateManagement 
    {
        public TimeSpan TotalBedtimeHours { get; set; }
        public TimeSpan TotalOvertimeHours { get; set; }
        public TimeSpan TotalHoursBeforeBedtime { get; set; }
    }

你走在正确的轨道上。您正在构建数据实例。

将这个以及另外两个类似的实例传递给_business的构造函数。

您的RateManagement和TimeManagement似乎是简单的数据对象，因此无需使用框架或任何东西进行模拟。您可以使用数据传递实际实例。
