Question

我有一个Employee类，其中一个方法未实现

namespace Employee
{
    public class Employee
    {
        public virtual DateTime getDateOfJoining(int id)
        {
            throw new NotImplementedException();
        }
    }
}

我想模仿这个，我期待该方法返回当前的DateTime。

namespace Employee.Tests
{
    [TestClass]
    public class UnitTest1
    {
        [TestMethod]
        public void getJoiningDateMock()
        {
            var employee = new Mock<Employee>();
            employee.Setup(x => x.getDateOfJoining(It.IsAny<int>())).Returns((int x) => DateTime.Now);

            var objEmp = new Employee();

            Assert.AreEqual(DateTime.Now, employee.getDateOfJoining(1));
        }
    }
}

我调用Mock的方式不正确。我在这里缺少什么，特别是如何编写AssertEquals？

以下仅确认模拟的行为与设置相同。

[TestClass]
public class UnitTest1 {
    [TestMethod]
    public void getJoiningDateMock() {
        //Arrange
        var expected = DateTime.Now;
        var employeeMock = new Mock<Employee>();
        employeeMock
            .Setup(x => x.getDateOfJoining(It.IsAny<int>()))
            .Returns(expected);

        var objEmp = employeeMock.Object;

        //Act
        var actual = objEmp.getDateOfJoining(1);

        //Assert
        Assert.AreEqual(expected, actual);
    }
}
