I am encountering an issue using Rhino Mocks which I hope you can
advise me on please. I have tried to demonstarte in the attached
solution in VS2005 C#
The method that I wish to test is someClass.MethodToTest(). This
method calls ModelManager.Instance.GetModels().GetEntity() so I have
tried to create a Dynamic mock object to mock the response from this
method. I have been unsuccessful and ask for your advise please. An
exception is raised when I call Expect.Call
Thank you
Source code is as follows
using System;
using NUnit.Framework;
using Rhino.Mocks;
namespace RhinoMocksTester
{
public class AnEntity
{
private int m_id;
public int Id
{
get { return m_id;}
}
public AnEntity(int id)
{
m_id = id;
}
}
public interface IModel
{
AnEntity GetEntity();
}
public interface IModelManager
{
IModel GetModels();
}
public class Model : IModel
{
public AnEntity GetEntity()
{
return new AnEntity(5);
}
}
public class ModelManager : IModelManager
{
private static Model m_Models;
private static ModelManager m_modelManager = new ModelManager
();
private ModelManager()
{
}
public static ModelManager Instance
{
get
{
return m_modelManager;
}
}
public IModel GetModels()
{
if (m_Models == null)
m_Models = new Model();
return m_Models;
}
}
public class SomeClass : IDisposable
{
private AnEntity m_anEntity;
public int Id
{
get { return m_anEntity.Id; }
}
public void MethodToTest()
{
m_anEntity = ModelManager.Instance.GetModels().GetEntity
();
}
public void Dispose()
{
}
}
[TestFixture]
public class Tests
{
[Test]
public void LookupEntityTest()
{
MockRepository mocks = new MockRepository();
// Create a dynamic mock object to process interaction
with the ModelManager interface
IModelManager mm = mocks.DynamicMock<IModelManager>();
// Create an entity to return when
ModelManager.Instance.GetModel().GetEntity() is called
AnEntity anEntity = new AnEntity(6);
Expect.Call(mm.GetModels().GetEntity()).Return
(anEntity).IgnoreArguments();
mocks.ReplayAll();
// Execute the test method
SomeClass someClass = new SomeClass();
someClass.MethodToTest();
Assert.AreEqual(6,someClass.Id);
}
}
}
