OK - I found the problem. I just would like to know why it caused me so much heart-ache. This code compiles but it will not run - the Exception caused me a lot of grief also - italicized below. As soon as I change the FakeAnother property to a member instead of a property, everything works happily.

TypeMock.TypeMockException occurred
Message=" *** No method with name Setup>b__1 in type GenericBaseClassTest exists."


It looks like the "Setup>b__1 in type GenericBaseClassTest" has overwritten the real missing method name.

using System;
using System.Reflection;
using NUnit.Framework;
using TypeMock;
using TypeMock.ArrangeActAssert;

[TestFixture]
[ClearMocks]
public class GenericBaseClassTest : TestBaseClass<TestController>
{
    private IAnother _another;
    protected IAnother FakeAnother
    {
        get { return _another; }
        set { _another = value; }
    }

    [SetUp]
    public void Setup()
    {
        FakeAnother = Isolate.Fake.Instance<IAnother>(Members.ReturnRecursiveFakes);
        Isolate.WhenCalled(() => ServiceFactory.CreateInstance()).WillReturn(FakeSvcFactory);
        Isolate.WhenCalled(() => FakeSvcFactory.ReturnAnother()).WillReturn(FakeAnother);
        Isolate.WhenCalled(() => FakeAnother.GetObject()).WillReturn(null);
    }

    public void Test1()
    {
        Controller.DoSomething();
    }

public interface IAnother
{
    object GetObject();
}

public class Another : IAnother
{
    public object GetObject()
    {
        return new object();
    }
}

public class ServiceFactory
{
    public static ServiceFactory CreateInstance()
    {
        return new ServiceFactory();
    }

    public IAnother ReturnAnother()
    {
        return new Another();
    }
}

public class TestBaseClass<C> where C : TestController
{
    protected F FakeSvcFactory;
    protected C Controller;

    protected TestBaseClass()
    {
        //create a factory instance
        FakeSvcFactory = Isolate.Fake.Instance<F>();
        Isolate.Fake.StaticMethods<F>(Members.ReturnRecursiveFakes);
        //create the controller
        ConstructorInfo ci = typeof (C).GetConstructor(new Type[] {typeof (F)});
        //inject the factory into the controller
        Controller = ci.Invoke(new object[] {FakeSvcFactory}) as C;
    }
}

public class TestController
{
    private ServiceFactory _sf;

    public TestController()
    {}

    public TestController(ServiceFactory sf)
    { _sf = sf; }

    public void DoSomething()
    {
        IAnother a = _sf.ReturnAnother();
    }
}

Hi

What happens is that in the line:
Isolate.WhenCalled(() => FakeAnother.GetObject()).WillReturn(null);

you are trying to fake the Test class (GenericBaseClassTest) property
and not IAnother.GetObject method as you intended.

:idea: If it's possible I would make the test code simpler. i.e
The test class would not be derived from base class and each test will create its own fakes.
I think that would make the test code easier to read and can
save you some grief :wink:

Sorry about the double post.

I am trying to replicate the current code that I am testing (unsuccessfully) as best I can in portable code - hence the base classes and such.

I am ran into the same problem again in my real code. I am telling the service factory to return a faked object and it is not even after I removed the protected properties and replace them with protected variables.

Can you give me a correct example of how I can solve the problem that you are explaining?

So I think I understand a little better now after thumping my head on the desk. The problem is that I need to call a public method on a nonpublic property. Is this possible or would I be better off using one of the other APIs?

Actually, I was correct in the beginning. Turns out my REAL code was failing due to this bug...

The bug described in post https://www.typemock.com/community/viewt ... 43&forum=9 was solved in Isolator version 5.1.1.

please download an update and see if it solves your problem.

Sorry for the mistake.
The issue was solved after version 5.1.1.
I sent you a patch that should solve this issue.
