Я использую Ninject.Extensions.Factory с Ninject 3 для создания factory, который создает разные типы IFoo
на основе строки, предоставленной factory. У меня есть прохождение unit test, но, как ни странно, только в тестировщике Resharper. В тестовом бегуне NCrunch он терпит неудачу. Это проблема с конфигурацией NCrunch или мне нужно изменить код?
Интерфейс:
public interface IFooFactory
{
IFoo CreateFoo(string name);
}
Связи Ninject:
kernel.Bind<IFooFactory>().ToFactory(() => new UseFirstParameterAsNameInstanceProvider());
kernel.Bind<IFoo>().To<BarFoo>().Named("Bar");
Тест:
[Test]
public void CanCreateFooTest()
{
var factory = (IFooFactory) Kernel.GetService(typeof(IFooFactory));
var bar = factory.CreateFoo("Bar");
Assert.AreEqual(typeof(BarFoo), bar.GetType());
}
И исключение NCrunch:
System.Reflection.TargetInvocationException : Exception has been thrown by the target of an invocation.
----> Ninject.ActivationException : Error activating IInterceptor using conditional implicit self-binding of IInterceptor
Provider returned null.
Activation path:
2) Injection of dependency IInterceptor into parameter of constructor of type IFooFactoryProxy
1) Request for IFooFactory
Suggestions:
1) Ensure that the provider handles creation requests properly.
