HttpHandler模​​拟，单元测试（NUnit）设置问题

Question

此帖与其他两个帖子相关，here和here。我的新单元测试&嘲笑。我有一个测试装置试图模拟包括响应和请求的HttpContext对象。我认为测试代码没有正确设置，因为在调用处理程序后，我立即得到一个错误。我得到的错误是：

UnitTests.UADHandlerFixture.Request_Is_Object： System.NullReferenceException：未将对象引用设置为对象的实例。

在BaseHttpHandler.cs

在Abstract.BaseHttpHandler.get_Request（）：在BaseHttpHandler.cs线21

在Abstract.BaseHttpHandler.get_IsRequestFromUAD（）：23行

在Handlers.UADTimeHttpHandler.ProcessRequest（HttpContextBase上下文）中UADTimeHttpHandler.cs：线19

在UnitTests.UADHandlerFixture.Request_Is_Object（）在UADHttpHanderTests.cs：管线47

测试代码是这样的：

[TestFixture] 
public class UADHandlerFixture 
{ 
    private Mock<HttpContextBase> _mockHttpContext; 
    private Mock<HttpRequestBase> _mockHttpRequest; 
    private Mock<HttpResponseBase> _mockHttpResponse; 
    private UADTimeHttpHandler _handler; 
    private WindsorContainer _container; 

    [SetUp] 
    public void Init() 
    { 
     _mockHttpRequest = new Mock<HttpRequestBase>(); 
     _mockHttpResponse = new Mock<HttpResponseBase>(); 
     _mockHttpContext = new Mock<HttpContextBase>(); 
     _container = new WindsorContainer(); 
     _container.AddComponent<ILogger, FakeLogger>(); 
     _container.AddComponent<IDataRepository, FakeDataRepository>(); 

     _mockHttpContext.SetupGet(x => x.Application[0]).Returns(_container); 
     _mockHttpContext.SetupGet(x => x.Request).Returns(_mockHttpRequest.Object); 
     _mockHttpContext.SetupGet(x => x.Response).Returns(_mockHttpResponse.Object); 

     _handler = new UADTimeHttpHandler(); 
    } 

    [Test] 
    public void Request_Is_Object() 
    { 
     _handler.ProcessRequest(_mockHttpContext.Object); 
    } 
} 

处理程序：

public class UADTimeHttpHandler : BaseHttpHandler 
{ 
    public override void ProcessRequest(HttpContextBase context) 
    { 
     if (IsRequestFromUAD) 
     { 
      Logger.Log("Log stuff"); 
      DataRepository.Write("DB stuff"); 
      ReturnResponse(HttpStatusCode.OK, DateTime.Now.ToString()); 
     } 
     else 
      ReturnResponse(HttpStatusCode.BadRequest); 
    } 
} 

BaseHandler：

public abstract class BaseHttpHandler : IHttpHandler 
{ 
    private HttpContext _httpContext; 
    private ILogger _logger; 
    private IDataRepository _dataRepository; 
    protected ILogger Logger { get { return _logger; } } 
    protected IDataRepository DataRepository { get { return _dataRepository; } } 
    protected HttpContext Context { get { return _httpContext; } } 
    protected HttpRequest Request { get { return _httpContext.Request; } } 
    protected HttpResponse Response { get { return _httpContext.Response; } } 
    protected bool IsRequestFromUAD { get { return Request.UserAgent == null ? false : Request.UserAgent.Equals("UAD"); } } 
    public virtual bool IsReusable { get { return false; } } 

    public void ProcessRequest(HttpContext context) 
    { 
     WindsorContainer container = (WindsorContainer)context.Application[0]; 
     _logger = container.Resolve<ILogger>(); 
     _dataRepository = container.Resolve<IDataRepository>(); 

     _httpContext = context; 
     ProcessRequest(new HttpContextWrapper(context)); 
    } 

    protected virtual void ReturnResponse(HttpStatusCode httpStatus) 
    { 
     Response.StatusCode = (int)httpStatus; 
    } 

    protected virtual void ReturnResponse(HttpStatusCode httpStatus, string response) 
    { 
     Response.StatusCode = (int)httpStatus; 
     Response.Write(response); 
    } 

    protected virtual string GetInputStream() 
    { 
     using (var reader = new StreamReader(Request.InputStream)) 
     { 
      return reader.ReadToEnd(); 
     } 
    } 

    public abstract void ProcessRequest(HttpContextBase context); 
}

我误解你的职位。无视这个答案。

我很好奇你在库上调用Dispose（）的地方。
