我正在尝试通过 Moq 在我的项目（.net core 3.1）中测试 ILogger（Microsoft.Extensions.Logging），但是...它失败了..我试图捕获代码中的异常：

  try{
      //do something
     }
    catch (Exception e)
            {
                _logger.LogError(new
                {
                    RequestId = requestId.ToString(),
                    Topic = "Merge files",
                    Message = "process failed",
                    Status = "Failed"
                }, e);
            }

我定义了模拟记录器

private readonly Mock<ILogger<MyClass>> _logger = new Mock<ILogger<MyClass>>();

这是我的 UT

_logger.Verify(
                x => x.Log(
                    It.IsAny<LogLevel>(),
                    It.IsAny<EventId>(),
                    It.Is<It.IsAnyType>((v, t) => true),
                    It.IsAny<Exception>(),
                    It.Is<Func<It.IsAnyType, Exception, string>>((v, t) => true)), Times.Once);

我调试了它，在我的代码中执行了日志异常方法，但最后 UT 失败，因为我收到以下消息：

预期在模拟上调用一次，但实际调用次数为 0 次： x => x.Log<It.IsAnyType>(It.IsAny(), It.IsAny(), It.Is<It.IsAnyType>((v, t) => True), It.IsAny(), It.Is<Func<It.IsAnyType, Exception, string>>((v, t) …

我想通过模拟两个MailMessage和使用moq测试下面的方法SmptpClient

public void SendEmail(string emailAddress, string subject, string body)
{
    using (var mail = new MailMessage(NoReplyEmailAddress, emailAddress))
    {
        mail.Subject = subject;
        mail.Body = body;
        mail.IsBodyHtml = true;

        using (var client = new SmtpClient())
        {
            client.Host = SmtpHost;
            client.Port = SmtpPort;
            client.DeliveryMethod = SmtpDeliveryMethod.Network;
            client.Send(mail);
        }
    }
}

我的测试方法是:

public void TestSendEmail()
{
    Mock<MailMessage> mailMessageMock = new Mock<MailMessage>();
    MailMessage message = (MailMessage)mailMessageMock.Setup(m => new MailMessage()).Returns(mailMessageMock.Object);
    Mock<SmtpClient> smtpClientMock = new Mock<SmtpClient>();
    smtpClientMock.Setup(s => new SmtpClient()).Returns(smtpClientMock.Object);

    EmailService emailService = new …

以下构造函数参数没有用于使用 moq 和 xunit 进行单元测试的匹配装置数据。

已经使用依赖注入和模拟来测试类。

//this is how i register the DI.
services.AddScoped<IWaktuSolatServiceApi, WaktuSolatServiceApi>(); 


 public interface IWaktuSolatServiceApi
 {
    Task<Solat> GetAsyncSet();
 }


// the unit test. 
public class UnitTest1 
{
    Mock<IWaktuSolatServiceApi> waktu;

    public UnitTest1(IWaktuSolatServiceApi waktu)
    {
        this.waktu = new Mock<IWaktuSolatServiceApi>();
    }

    [Fact]
    public async Task ShoudReturn()
    {
        var request = new Solat
        {
            zone = "lala"
        };

        var response = waktu.Setup(x => 
        x.GetAsyncSet()).Returns(Task.FromResult(request));
    }
}

但是我收到此错误以下构造函数参数没有匹配的夹具数据。

验证方法测试调用失败： .Net Core 3.1、Framework 4.8

正在测试的方法：为简洁起见，代码简化。

public bool IsValidPhoneNumber(string value)
{
    return value.Length == 10;
}

完整的测试类（通过）：

public class CustomersViewModelTest
{
    private CustomerViewModel _sut;
    private readonly Mock<ICustomerViewModel> _customerViewModel;
    private readonly Mock<ICustomerRepository> _customerRepository;
    private readonly Mock<IMapper> _mapper;
    public CustomersViewModelTest()
    {
        _customerViewModel = new Mock<ICustomerViewModel>();
        _customerRepository = new Mock<ICustomerRepository>();
        _mapper = new Mock<IMapper>();

        _sut = new CustomerViewModel(_customerRepository.Object, _mapper.Object);
    }

    [Fact]
    public void PhoneNumberTest()
    {
        
        string phoneNumber = "123456789";
        _customerViewModel.Setup(x => x.IsValidPhoneNumber(phoneNumber)).Returns(false);
   
        bool result = _sut.IsValidPhoneNumber(phoneNumber);

        Assert.False(result);

    }
    
}

现在，如果我尝试验证方法调用，测试将失败：（断言被删除） …

我是 TDD 新手，能否请您使用 moq 编写测试用例以获取以下代码 -

public async Task<Model> GetAssetDeliveryRecordForId(string id)
{
    var response = await client.GetAsync($"api/getdata?id={id}");
    response.EnsureSuccessStatusCode();
    var result = await response.Content.ReadAsAsync<Model>();
    return result;
}

提前致谢。

.NET 中是否有任何可以模拟系统时间的模拟库，无论哪个模拟库对我来说都可以，例如 moq 等？
