### Question:
OfOverlayL3NatAug implements EpRendererAugmentation, AutoCloseable { @Override public Map.Entry<Class<? extends Augmentation<Endpoint>>, Augmentation<Endpoint>> buildEndpointAugmentation( RegisterEndpointInput input) { return null; } OfOverlayL3NatAug(EpRendererAugmentationRegistry epRendererAugmentationRegistry); @Override Map.Entry<Class<? extends Augmentation<Endpoint>>, Augmentation<Endpoint>> buildEndpointAugmentation(
            RegisterEndpointInput input); @Override Map.Entry<Class<? extends Augmentation<EndpointL3>>, Augmentation<EndpointL3>> buildEndpointL3Augmentation(
            RegisterEndpointInput input); @Override Map.Entry<Class<? extends Augmentation<EndpointL3Prefix>>, Augmentation<EndpointL3Prefix>> buildL3PrefixEndpointAugmentation(
            RegisterL3PrefixEndpointInput input); @Override void close();  }### Answer:
@Test public void testBuildEndpointAugmentation() { RegisterEndpointInput input = new RegisterEndpointInputBuilder().build(); assertNull(ofOverlayL3NatAug.buildEndpointAugmentation(input)); }
