 * Assume this is the test suite for `class Class`
 * in module 'module'.
 *
 * Document the file as follows.  (Note: for purposes of this
 * illustration Doxygen comments are set off with triple  `\\\\\\';
 * you should use the normal Javadoc format. )
 *
 * Add it to the groups module-tests and class-tests:
 *
 * \verbatim /// \file
/// \ingroup module-tests
/// \ingroup class-tests
/// Class test suite. \endverbatim
 *
 * Define the class-tests group:
 * \verbatim /// \ingroup module-tests
/// \defgroup class-tests Class test suite \endverbatim
 *
 * Make sure test.h is included:
 * \verbatim #include "ns3/test.h" \endverbatim
 *
 * Put the test code in namespace ns3::tests.
 * \verbatim namespace ns3 {
  namespace tests { \endverbatim
 *
 * Write your test cases and final test suite, and put them in
 * your test group:
 * \verbatim /// \ingroup class-tests
class ClassTestSuite : public TestSuite {...}; \endverbatim
 *
 * Create a static variable to hold the instance of your test suite:
 * \verbatim /// \ingroup class-tests
/// ClassTestSuite instance variable.
static ClassTestSuite g_classTestSuite; \endverbatim
 *
 * Finally, close the ingroup and namespace blocks:
 * \verbatim   }  // namespace tests
}  // namespace ns3 \endverbatim
