Moq-如何模拟Web服务调用? [英] Moq - How to mock web service call?

问题描述

下面的using击中了一个我不想实际击中的外部资源.我想测试someResult以及使用它的代码，但是每次我运行单元测试时，该代码仍然尝试访问真正的Web服务.如何使用moq伪造对Web服务的真实调用，而不在使用过程中模拟其余代码?

The using below hits an external resource that I do not want to actually hit. I want to test someResult and the code that uses it, but every time I run my unit test, this code still tries to hit the real web service. How do I use moq to fake the real call to the web service, but not mock the rest of the code within the using?

public IMyInterface.SomeMethod()
{    
     // hits a web service
     using ( mySoapClient client = new mySoapClient() )
     {
          var someResult = client.DoSomething();
       ...
       ...
     }
}


[TestMethod()]
public void SomeMethodTest()
{
    IMyInterface target = new MyInterface();
    target.SomeMethod();

    // Assert....
}

推荐答案

您需要将Web服务实现与使用者分离开来

You need to decouple the web service implementation from the consumer

public class ClassIWantToTest
{
      public ClassIWantToTest(IServiceIWantToCall service) {}

      public void SomeMethod()
      {
           var results = service.DoSomething();
           //Rest of the logic here
      }
}

现在，您可以使用Moq来模拟IServiceIWantToCall，以测试SomeMethod

Now you can use Moq to mock the IServiceIWantToCall in order to test the logic of SomeMethod
