如何使用 Moq 模拟 Web 服务调用? [英] How to mock web service call with Moq?

问题描述

下面的 using 命中了我不想实际命中的外部资源.我想测试 someResult 和使用它的代码，但每次我运行我的单元测试时，这段代码仍然试图访问真正的 Web 服务.我如何使用 moq 来伪造对 Web 服务的真实调用，但不模拟使用中的其余代码?

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

你需要将Web服务实现与消费者解耦

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
