### Question:
ResourceChanges { public void setAffectedVnffgs(List<AffectedVnffg> affectedVnffgs) { this.affectedVnffgs = affectedVnffgs; }  List<AffectedVnf> getAffectedVnfs(); void setAffectedVnfs(List<AffectedVnf> affectedVnfs); List<AffectedPnf> getAffectedPnfs(); void setAffectedPnfs(List<AffectedPnf> affectedPnfs); List<AffectedVirtualLink> getAffectedVls(); void setAffectedVls(List<AffectedVirtualLink> affectedVls); List<AffectedVnffg> getAffectedVnffgs(); void setAffectedVnffgs(List<AffectedVnffg> affectedVnffgs); List<AffectedNs> getAffectedNss(); void setAffectedNss(List<AffectedNs> affectedNss); List<AffectedSap> getAffectedSaps(); void setAffectedSaps(List<AffectedSap> affectedSaps);  }### Answer:
@Test public void setAffectedVnffgs() { resourceChanges.setAffectedVnffgs(new List<AffectedVnffg>() { @Override public int size() { return 0; } @Override public boolean isEmpty() { return false; } @Override public boolean contains(Object o) { return false; } @Override public Iterator<AffectedVnffg> iterator() { return null; } @Override public Object[] toArray() { return new Object[0]; } @Override public <T> T[] toArray(T[] a) { return null; } @Override public boolean add(AffectedVnffg affectedVnffg) { return false; } @Override public boolean remove(Object o) { return false; } @Override public boolean containsAll(Collection<?> c) { return false; } @Override public boolean addAll(Collection<? extends AffectedVnffg> c) { return false; } @Override public boolean addAll(int index, Collection<? extends AffectedVnffg> 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 AffectedVnffg get(int index) { return null; } @Override public AffectedVnffg set(int index, AffectedVnffg element) { return null; } @Override public void add(int index, AffectedVnffg element) { } @Override public AffectedVnffg remove(int index) { return null; } @Override public int indexOf(Object o) { return 0; } @Override public int lastIndexOf(Object o) { return 0; } @Override public ListIterator<AffectedVnffg> listIterator() { return null; } @Override public ListIterator<AffectedVnffg> listIterator(int index) { return null; } @Override public List<AffectedVnffg> subList(int fromIndex, int toIndex) { return null; } }); }
