我正在使用 xUnit 和 Moq 来编写测试用例。我正在使用下面的代码创建一个 Mock，但遇到了突出显示的问题。

CloudBlockBlob source = null;
AccessCondition sourceAccessCondition = null;
AccessCondition destAccessCondition = null;
BlobRequestOptions options = null;
OperationContext operationContext = null;
CloudBlobContainer container = new CloudBlobContainer(uri);
Task task = null;
DeleteSnapshotOption deleteSnapshotOption = new DeleteSnapshotOption();

var mockCloudBlobClient = new Mock<Microsoft.WindowsAzure.Storage.Blob.CloudBlobClient>();
mockCloudBlobClient.Setup(repo => repo.GetContainerReference("sample")).Returns(container);

var mockCloudBlobContainer = new Mock<Microsoft.WindowsAzure.Storage.Blob.CloudBlobContainer>(uri);
mockCloudBlobContainer.Setup(repo => repo.GetBlockBlobReference("sample")).Returns(new CloudBlockBlob(uri));

var mockBlobServiceProvider = new Mock<BlobServiceProvider>();
mockBlobServiceProvider.Setup(repo => repo.GetBlockBlobContainer("sample")).Returns(new CloudBloblContainer(new Uri("http://mytest")));

该行mockBlobServiceProvider.Setup(repo => repo.GetBlockBlobContainer("sample")).Returns(new CloudBloblContainer(new Uri("http://mytest")));给了我这个错误：

System.NotSupportedException: '不支持的表达式：repo => repo.GetBlockBlobContainer("sample")

不可覆盖的成员（此处：BlobServiceProvider.GetBlockBlobContainer）不得用于设置/验证表达式。

我正在尝试模拟 HttpClient 的 PostAsync()，但出现错误。

下面是用于模拟的代码：

   public TestADLS_Operations()
    {
        var mockClient = new Mock<HttpClient>();
        mockClient.Setup(repo => repo.PostAsync(It.IsAny<string>(), It.IsAny<HttpContent>())).Returns(() => Task.FromResult(new HttpResponseMessage(HttpStatusCode.OK)));

        this._iADLS_Operations = new ADLS_Operations(mockClient.Object);
    }

错误：

不支持的表达式：repo => repo.PostAsync(It.IsAny(), It.IsAny()) 不可覆盖的成员（此处：HttpClient.PostAsync）不能在设置/验证表达式中使用。

在 .Net Core 中使用 xUnit 和 Moq 编写测试用例时遇到突出问题

我已经使用 MSTest Fakes 在下面编写了测试用例。它按预期工作正常。

 [TestClass]
public class TestBlobServiceProvider
{
    private Common.Interfaces.IBlobServiceProvider _iblobprovider;

    public TestBlobServiceProvider()
    {
        Common.Interfaces.IBlobServiceProvider iblobprovider = new BlobServiceProvider();
        this._iblobprovider = iblobprovider;
    }

    public TestBlobServiceProvider(string storageConnectionString)
    { 

    }


    [TestMethod]
    public void Move_Success()
    {
        using (ShimsContext.Create())
        {
            string sourceContainer = "a";
            string destinationContainer = "s";
            string sourceFileName = "d";
            string destinationFileName = "e";

            Microsoft.WindowsAzure.Storage.Blob.Fakes.ShimCloudBlockBlob sourceFile = new Microsoft.WindowsAzure.Storage.Blob.Fakes.ShimCloudBlockBlob ();
            Microsoft.WindowsAzure.Storage.Blob.Fakes.ShimCloudBlockBlob destFile = new Microsoft.WindowsAzure.Storage.Blob.Fakes.ShimCloudBlockBlob();

我在测试类中使用以下代码来测试catch()另一个类方法

private readonly  IADLS_Operations _iADLS_Operations;

[Fact]
public void CreateCSVFile_Failure()
{
    var dtData = new DataTable();
    string fileName = "";
   var   mockClient = new Mock<IHttpHandler>();

    this._iADLS_Operations = new ADLS_Operations(mockClient.Object);

    mockClient.Setup(repo => repo.PostAsync(It.IsAny<string>(), It.IsAny<HttpContent>(), It.IsAny<string>()))
        .Returns(() => Task.FromResult(new HttpResponseMessage(HttpStatusCode.BadRequest)));

    mockClient.Setup(repo => repo.SendAsync(It.IsAny<HttpRequestMessage>(), It.IsAny<string>()))
        .Returns(() => Task.FromResult(new HttpResponseMessage(HttpStatusCode.BadRequest)));  // here I want to return Exception instead of BadRequest. How to do that.

    Exception ex = Assert.Throws<Exception>(() => this._iADLS_Operations.CreateCSVFile(dtData, fileName).Result);
    Assert.Contains("Exception occurred while executing method:", ex.Message);
} …

目前我正在为遥测类编写测试用例。

 public  class TelemetryClientMock : ITelemetryClientMock
    {
       public string key { get; set; } //I want to mock key variable.
        private TelemetryClient telemetry;  
        public TelemetryClientMock( )
        {
            telemetry = new TelemetryClient() { InstrumentationKey = key };
        }



        public void TrackException(Exception exceptionInstance, IDictionary<string, string> properties = null)
        {

              telemetry.TrackException(exceptionInstance, properties);
        }

        public void TrackEvent(string eventLog)
        {
            telemetry.TrackEvent(eventLog);
        }

    }

在测试类中，我如何模拟关键变量。我曾经为模拟方法编写以下代码。

          [Fact]
            public void TrackException_Success()
            {
                Exception ex=null;
                IDictionary<string, string> dict = null;
               var reader = new …
