### Question:
ImmutableSortOptionEntry implements SortOptionEntry { public static ImmutableSortOptionEntry desc(final CharSequence propertyPath) { return new ImmutableSortOptionEntry(propertyPath, SortOrder.DESC); } ImmutableSortOptionEntry(final CharSequence propertyPath, final SortOrder sortOrder); static ImmutableSortOptionEntry of(final CharSequence propertyPath, final SortOrder sortOrder); static ImmutableSortOptionEntry asc(final CharSequence propertyPath); static ImmutableSortOptionEntry desc(final CharSequence propertyPath); @Override JsonPointer getPropertyPath(); @Override SortOrder getOrder(); @Override boolean equals(final Object o); @Override int hashCode(); @Override String toString();  }### Answer:
@Test(expected = NullPointerException.class) public void tryToCreateDescendingEntryWithNullPath() { ImmutableSortOptionEntry.desc(null); }
