ServiceLocator未在测试项目中初始化

Question

当我尝试编写与我的新任务(MVC3,S#arp 2.0)相关的测试时,我在尝试运行测试时遇到此错误:

MyProject.Tests.MyProject.Tasks.CategoryTasksTests.CanConfirmDeleteReadiness:SetUp:System.NullReferenceException:ServiceLocator尚未初始化; 我试图检索SharpArch.NHibernate.ISessionFactoryKeyProvider ----> System.NullReferenceException:对象引用未设置为对象的实例.

在SharpArch.NHibernate.NHibernateRepositoryWithTypedId的SharpArch.Domain.SafeServiceLocator 1.GetService() at SharpArch.NHibernate.SessionFactoryKeyHelper.GetKeyFrom(Object anObject) at SharpArch.NHibernate.NHibernateRepositoryWithTypedId2.get_Session()2.Save(T entity) at MyProject.Tests.MyProject.Tasks.CategoryTasksTests.Setup() in C:\code\MyProject\Solutions\MyProject.Tests\MyProject.Tasks\CategoryTasksTests.cs:line 36 --NullReferenceException at Microsoft.Practices.ServiceLocation.ServiceLocator.get_Current() at SharpArch.Domain.SafeServiceLocator1.GetService()

其他不涉及新类的测试(例如,生成/确认数据库映射)正确运行.

我的ServiceLocatorInitializer如下

public class ServiceLocatorInitializer
{

public static void Init() 
{
    IWindsorContainer container = new WindsorContainer();

        container.Register(
                Component
                    .For(typeof(DefaultSessionFactoryKeyProvider))
                    .ImplementedBy(typeof(DefaultSessionFactoryKeyProvider))
                    .Named("sessionFactoryKeyProvider"));

    container.Register(
            Component
                .For(typeof(IEntityDuplicateChecker))
                .ImplementedBy(typeof(EntityDuplicateChecker))
                .Named("entityDuplicateChecker"));

    ServiceLocator.SetLocatorProvider(() => new WindsorServiceLocator(container));
}
}

您正在注册DefaultSessionFactoryKeyProvider作为DefaultSessionFactoryKeyProvider的实现,而您依赖于ISessionFactoryKeyProvider,由于没有为该接口注册任何实现,因此windsor城堡不知道如何解决.

我认为应该是:

container.Register(Component .For(typeof(ISessionFactoryKeyProvider)).ComplempleBy(typeof(DefaultSessionFactoryKeyProvider)).Named("sessionFactoryKeyProvider"));
