Windsor RC3: Can't resolve instance from Kernel

[Derick Bailey]

Hello,

I'm trying to register an instance of a component in my unit tests (a
mock or a standard instance) and the resolution is failing.

I'm using Windsor RC3 with Visual Studio 2008 / .NET 3.5 / C#

using Castle.Windsor;
using NUnit.Framework;
using Rhino.Mocks;

namespace SigmaDelta.Test
{
[TestFixture]
public class ShowDialogCommandFixture
{
[Test]
public void TestDynamicMock()
{
MockRepository mockRepository = new MockRepository();
IShowDialogCommand showDialogCommand =
mockRepository.DynamicMock<IShowDialogCommand>();

IWindsorContainer container = new WindsorContainer();

container.Kernel.AddComponentInstance<IShowDialogCommand>(showDialogCommand);

Assert.AreSame(showDialogCommand,
container.Resolve<IShowDialogCommand>());
}

[Test]
public void TestStandardInstance()
{
MockRepository mockRepository = new MockRepository();
IShowDialogCommand showDialogCommand = new ShowDialogCommand();

IWindsorContainer container = new WindsorContainer();

container.Kernel.AddComponentInstance<IShowDialogCommand>(showDialogCommand);

Assert.AreSame(showDialogCommand,
container.Resolve<IShowDialogCommand>());
}
}

public class ShowDialogCommand : IShowDialogCommand
{

}

public interface IShowDialogCommand
{
}
}

the above unit tests produce these errors:

Error 1 TestCase
'SigmaDelta.Test.ShowDialogCommandFixture.TestDynamicMock'

....

Am i doing something wrong? or is this a problem in Windsor/RC3?

Hi,

I am not sure if it's a bug, but it looks like it because this call behaves differently on trunk.

Three workarounds:

1. container.Kernel.AddComponentInstance<IShowDialogCommand>(typeof(IShowDialogCommand), showDialogCommand);
2. container.Kernel.AddComponentInstance(typeof(IShowDialogCommand).FullName, typeof(IShowDialogCommand), showDialogCommand);
3. Use the trunk :-)

I'll go with option #1 for now. Any idea when RC4 is going to be
released?
