### Question:
InstantiateNsRequest { public void setVnfInstanceData(List<VnfInstanceData> vnfInstanceData) { this.vnfInstanceData = vnfInstanceData; }  String getNsFlavourId(); void setNsFlavourId(String nsFlavourId); List<SapData> getSapData(); void setSapData(List<SapData> sapData); List<AddPnfData> getAddpnfData(); void setAddpnfData(List<AddPnfData> addpnfData); List<VnfInstanceData> getVnfInstanceData(); void setVnfInstanceData(List<VnfInstanceData> vnfInstanceData); List<String> getNestedNsInstanceId(); void setNestedNsInstanceId(List<String> nestedNsInstanceId); List<VnfLocationConstraint> getLocalizationLanguage(); void setLocalizationLanguage(List<VnfLocationConstraint> localizationLanguage); Map<String, Object> getAditionalParamsForNs(); void setAditionalParamsForNs(Map<String, Object> aditionalParamsForNs); List<ParamsForVnf> getAdditionalParamsForVnf(); void setAdditionalParamsForVnf(List<ParamsForVnf> additionalParamsForVnf); String getStartTime(); void setStartTime(String startTime); String getNsInstantiationLevelId(); void setNsInstantiationLevelId(String nsInstantiationLevelId); List<AffinityOrAntiAffinityRule> getAdditionalAffinityOrAntiAffiniityRule(); void setAdditionalAffinityOrAntiAffiniityRule(
            List<AffinityOrAntiAffinityRule> additionalAffinityOrAntiAffiniityRule);  }### Answer:
@Test public void setVnfInstanceData() { instantiateNsRequest.setVnfInstanceData(new List<VnfInstanceData>() { @Override public int size() { return 0; } @Override public boolean isEmpty() { return false; } @Override public boolean contains(Object o) { return false; } @Override public Iterator<VnfInstanceData> iterator() { return null; } @Override public Object[] toArray() { return new Object[0]; } @Override public <T> T[] toArray(T[] a) { return null; } @Override public boolean add(VnfInstanceData vnfInstanceData) { return false; } @Override public boolean remove(Object o) { return false; } @Override public boolean containsAll(Collection<?> c) { return false; } @Override public boolean addAll(Collection<? extends VnfInstanceData> c) { return false; } @Override public boolean addAll(int index, Collection<? extends VnfInstanceData> c) { return false; } @Override public boolean removeAll(Collection<?> c) { return false; } @Override public boolean retainAll(Collection<?> c) { return false; } @Override public void clear() { } @Override public VnfInstanceData get(int index) { return null; } @Override public VnfInstanceData set(int index, VnfInstanceData element) { return null; } @Override public void add(int index, VnfInstanceData element) { } @Override public VnfInstanceData remove(int index) { return null; } @Override public int indexOf(Object o) { return 0; } @Override public int lastIndexOf(Object o) { return 0; } @Override public ListIterator<VnfInstanceData> listIterator() { return null; } @Override public ListIterator<VnfInstanceData> listIterator(int index) { return null; } @Override public List<VnfInstanceData> subList(int fromIndex, int toIndex) { return null; } }); }
