Ninject3でNinject.Extensions.Factoryを使用してファクトリを作成していますIFoo
。ファクトリは、ファクトリに提供された文字列に基づいてさまざまなタイプを作成します。私は合格したユニットテストを持っていますが、奇妙なことに、Resharperテストランナーだけです。NCrunchテストランナーでは失敗します。これはNCrunch構成の問題ですか、それともコードを変更する必要がありますか?
インターフェース:
public interface IFooFactory
{
IFoo CreateFoo(string name);
}
Ninjectバインディング:
kernel.Bind<IFooFactory>().ToFactory(() => new UseFirstParameterAsNameInstanceProvider());
kernel.Bind<IFoo>().To<BarFoo>().Named("Bar");
テスト:
[Test]
public void CanCreateFooTest()
{
var factory = (IFooFactory) Kernel.GetService(typeof(IFooFactory));
var bar = factory.CreateFoo("Bar");
Assert.AreEqual(typeof(BarFoo), bar.GetType());
}
そしてNCrunchの例外:
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.
