How to mock a web service

Question

Do I have to rewrite my code to do this into an interface? Or is there an easier way? I am using Moq

Answer 1

What I usually do is build a wrapper or an adapter around my web service and just mock that.

for instance:

public class ServiceAdapter: IServiceAdapter
{
    public void CallSomeWebMethod()
    {
        var someService = new MyWebService();
        someService.SomeWebMethod();
    }
}

Then I just stub the service adapter.

[Test]    
public void SomeMethod_Scenario_ExpectedResult()
{
    var adapterMock = new Mock();
    //do your test
}
