<para>
This test environment also contains a reference to a memory usage checker
which can safely be ignored. It is also contained in the &app; environment
and is a great help if looking for memory leaks. Also notice the usage of
the C++ preprocessor directive <emphasis>#ifdef HAVE_LIBCPPUNIT</emphasis>
to avoid compile errors when CPPUNIT is not installed.
</para>
<para>
Another specialty that is not required by CPPUNIT is the specific
TestProgressListener. It is used here to print the name of the fixture that
is currently running. Since this method is called upon start of each
test case, some logic is necessary to print the name only once.
