Yönlendiriciyi casus olarak eklemem gerektiğini anlıyorum ama eğer SpyObj olarak ekler ve sağlayıcı olarak bildirirseniz aynı hatayı alırım.
Bu hatayı düzeltmem için daha iyi bir yol var mı? routerLink bilinen bir özelliği böylece RouterLinkStubDirective ve RouterOutletStubComponent kullanarak

hangi Açısal sürüm kullanıyorsunuz? Çünkü sağlayıcılar seçeneği, Angular 2'nin son yayınlanmış sürüm –
sürüm 2.1.0 kullanıyorum bileşen metadata yok. Yani, artık birim testleri için bir seçenek değil mi? Ben hala sağlayıcıları modüllerde kullandığınıza inanıyorum. Ben açısal tohum kullanıyorum ve hala örnekte: https://github.com/mgechev/angular-seed/blob/master/src/client/app/home/home.module.ts – Bhetzie
NavComponent'ın 'providers' seçeneği hakkında konuşun –
