一种常见的方法是moq()或rhinomock之类的模拟工具
由于它们不允许您模拟静态成员,您需要将调用包装到webcontext.current。下面是一个包装静态mmember并使用moq进行测试的示例:如果您还没有使用MS Fakes框架,那么这可能是过度杀伤力,但如果您已经使用了MS Fakes框架,那么这对我来说是可行的
using (ShimsContext.Create())
{
var response = new ShimOutgoingWebResponseContext();
var ctx = new ShimWebOperationContext
{
OutgoingResponseGet = () => response
};
ShimWebOperationContext.CurrentGet = () => ctx;
try
{
ParameterInspector.BeforeCall("operationName", new string[]{"some_argument"} );
}
catch (Exception e)
{
Assert.IsNull(e);
}
}
我遇到了同样的问题。我想在没有任何IIS的情况下对WCF服务函数(对于IOauth2接口,如下例)进行单元测试。这是准备工作的代码片段
// Prepare WebOperationContext
var factory = new ChannelFactory<IOauth2>(
new WebHttpBinding(),
new EndpointAddress("http://localhost:80"));
OperationContext.Current = new OperationContext(factory.CreateChannel() as IContextChannel);
Debug.Assert(WebOperationContext.Current != null);
//准备WebOperationContext
var工厂=新工厂(
新建WebHttpBinding(),
新端点地址(“http://localhost:80"));
OperationContext.Current=新的OperationContext(factory.CreateChannel()作为IContextChannel);
Assert(WebOperationContext.Current!=null);
我按照Sanjay的回答,尝试MS fake框架
首先,您必须打开“解决方案资源管理器>您的测试项目>参考”
=>右键单击“System.ServiceModel.Web”
=>按“添加伪造程序集”
参考:
样本:
现在,您可以在WCF服务代码中获得WebOperationContext.Current.IncomingRequest.Headers[“myCustomHeader”]
有关MSDN上MS Fakes框架的更多信息:
为您的服务创建一个客户端,然后在客户端内处理OperationContext:
public class AwesomeRestServiceClient : ClientBase<IAwesomeRestService>, IAwesomeRestService
{
public class AwesomeRestServiceClient(string address)
: base(new WebHttpBinding(), new EndpointAddress(address))
{
this.Endpoint.EndpointBehaviors.Add(new WebHttpBehavior());
}
public AwesomeSearchResults<AwesomeProductBase> GetAwesomeResultsAsXml()
{
using (new OperationContextScope(this.InnerChannel))
{
return base.Channel.GetAwesomeResultsAsXml();
}
}
}
公共类AwesomeRestServiceClient:ClientBase,IAwesomeRestService
{
公共类AwesomeRestServiceClient(字符串地址)
:base(新WebHttpBinding(),新端点地址(address))
{
this.Endpoint.EndpointBehaviors.Add(新的WebHttpBehavior());
}
公共AwesomeSearchResults。您希望您的测试做什么?您能告诉我这些(ShimOutgoingWebResponseContext和ShimWebOperationContext)在哪里吗?我的代码找不到它们,我正在尝试确定要包含哪些框架类。我已经包含了Microsoft.QualityTools.Testing.Fakes.ShimsContext.Create()正在提供NullReference异常。StackTrace:位于Microsoft.QualityTools.Testing.Fakes.UnitTestIsolation.TraceProfileInstrumentationProvider.TraceProfileMethods.ResolveProfilerPath(),位于Microsoft.QualityTools.Testing.Fakes.UnitTestIsolation.TraceProfileInstrumentationProvider.TraceProfileMethods..()
如何尝试以管理员身份运行VS并再次运行测试?我从System.TypeInitializationException-{“TraceProfilerMethods”的类型初始值设定项引发了一个异常。}很遗憾,Microsoft Fakes仅适用于Visual Studio的高级版本。请参见此处。
using (ShimsContext.Create())
{
var response = new ShimOutgoingWebResponseContext();
var request = new ShimIncomingWebRequestContext();
var ctx_hd = new WebHeaderCollection();
ctx_hd.Add("myCustomHeader", "XXXX");
request.HeadersGet = () => ctx_hd;
var ctx = new ShimWebOperationContext
{
OutgoingResponseGet = () => response,
IncomingRequestGet = () => request
};
ShimWebOperationContext.CurrentGet = () => ctx;
//Test your code here...
