Unit test Container for MEF

Hello
I am using MEF to resolve the requied Implementation. :)

Following is the Factory class which resolves the required implementaion. Static method "GetLocalisationProviderInstance()" get a appropriate implementaion.

Do I really need to test this? :?
How do I unit test this using typemock? :(





----CODE----
public class LocalisationProviderFactory
{
[ImportMany]
Lazy<ILocalisation, IDictionary<string>>[] LocalisationMainService { get; set; }

public LocalisationProviderFactory()
{
var Catalog = new AggregateCatalog();
Catalog.Catalogs.Add(new DirectoryCatalog(@".Extensions"));
var Container = new CompositionContainer(Catalog);
Container.ComposeParts(this);
}


public virtual List<ILocalisation> GetLocalisationService(string Type)
{
List<ILocalisation> FilteredLocalisationService = new List<ILocalisation>();
foreach (var LocalisationObj in LocalisationMainService)
{
if (LocalisationObj.Metadata["Type"].ToString().ToUpper() == Type)
FilteredLocalisationService.Add(LocalisationObj.Value);
}
return FilteredLocalisationService;
}

public static ILocalisation GetLocalisationProviderInstance()
{
string Option = ConfigurationSettings.AppSettings["LocalisationProviderName"].ToString();

LocalisationProviderFactory CF = new LocalisationProviderFactory();
List<ILocalisation> objLocalisation = CF.GetLocalisationService(Option.ToUpper());
if (objLocalisation.Count == 0)
{
//No Implementation Found
return null;
}
else
{
return (ILocalisation)objLocalisation[0];
}
}

}
