### Question:
SxpEndpointAugmentorImpl implements EndpointAugmentor { @Override public Entry<Class<? extends Augmentation<ContainmentEndpoint>>, Augmentation<ContainmentEndpoint>> buildContainmentEndpointAugmentation( ContainmentEndpointReg input) { return null; } SxpEndpointAugmentorImpl(final ReadableByKey<EpPolicyTemplateValueKey, EndpointPolicyTemplateBySgt> epPolicyTemplateDao,
                                   final EpPolicyTemplateValueKeyFactory epPolicyTemplateKeyFactory); @Override Entry<Class<? extends Augmentation<AddressEndpoint>>, Augmentation<AddressEndpoint>> buildAddressEndpointAugmentation(
            AddressEndpointReg input); @Override Entry<Class<? extends Augmentation<ContainmentEndpoint>>, Augmentation<ContainmentEndpoint>> buildContainmentEndpointAugmentation(
            ContainmentEndpointReg input); @Override Entry<Class<? extends Augmentation<AddressEndpointWithLocation>>, Augmentation<AddressEndpointWithLocation>> buildAddressEndpointWithLocationAugmentation(
            AddressEndpoint input); @Override Entry<Class<? extends Augmentation<ContainmentEndpointWithLocation>>, Augmentation<ContainmentEndpointWithLocation>> buildContainmentEndpointWithLocationAugmentation(
            ContainmentEndpoint input);  }### Answer:
@Test public void testBuildContainmentEndpointAugmentation() throws Exception { final ContainmentEndpointReg endpoint = new ContainmentEndpointRegBuilder().build(); Assert.assertNull(augmetor.buildContainmentEndpointAugmentation(endpoint)); }
