### Question:
Ordering implements Comparator<Object>, Serializable, XMLSerializable { public boolean isCaseInsensitive() { return !isCaseSensitive(); } Ordering();  Ordering(String sortPathSpec);  Ordering(String sortPathSpec, SortOrder sortOrder);  Ordering(Expression sortSpec);  Ordering(Expression sortSpec, SortOrder sortOrder); @SuppressWarnings("unchecked") static void orderList(List<?> objects, List<? extends Ordering> orderings); static List<E> orderedList(final Collection<E> objects, List<? extends Ordering> orderings); @Override boolean equals(Object object); @Override int hashCode(); void setSortSpecString(String sortSpecString); void setNullSortedFirst(boolean nullSortedFirst); boolean isNullSortedFirst(); void setPathExceptionSupressed(boolean pathExceptionSuppressed); boolean isPathExceptionSuppressed(); String getSortSpecString(); void setSortOrder(SortOrder order); boolean isAscending(); boolean isDescending(); void setAscending(); void setDescending(); boolean isCaseInsensitive(); boolean isCaseSensitive(); void setCaseInsensitive(); void setCaseSensitive(); Expression getSortSpec(); void setSortSpec(Expression sortSpec); void orderList(List<?> objects); List<E> orderedList(Collection<E> objects); @Override int compare(Object o1, Object o2); @Override void encodeAsXML(XMLEncoder encoder, ConfigurationNodeVisitor delegate); @Override String toString(); SortOrder getSortOrder(); Orderings then(Ordering nextOrdering); Orderings then(Orderings nextOrderings); Orderings then(List<Ordering> nextOrderings);  }### Answer:
@Test public void testCaseInsensitive3() { Ordering ord = new Ordering("M", SortOrder.ASCENDING_INSENSITIVE); assertTrue(ord.isCaseInsensitive()); }
@Test public void testCaseInsensitive4() { Ordering ord = new Ordering("N", SortOrder.ASCENDING); assertFalse(ord.isCaseInsensitive()); }
@Test public void testCaseInsensitive5() { Ordering ord = new Ordering("M", SortOrder.DESCENDING_INSENSITIVE); assertTrue(ord.isCaseInsensitive()); }
@Test public void testCaseInsensitive6() { Ordering ord = new Ordering("N", SortOrder.DESCENDING); assertFalse(ord.isCaseInsensitive()); }
