/*! \brief Manages TestListener.
 * \ingroup TrackingTestExecution
 *
 * A single instance of this class is used when running the test. It is usually
 * created by the test runner (TestRunner).
 *
 * This class shouldn't have to be inherited from. Use a TestListener
 * or one of its subclasses to be informed of the ongoing tests.
 * Use a Outputter to receive a test summary once it has finished
 *
 * TestResult supplies a template method 'setSynchronizationObject()'
 * so that subclasses can provide mutual exclusion in the face of multiple
 * threads.  This can be useful when tests execute in one thread and
 * they fill a subclass of TestResult which effects change in another
 * thread.  To have mutual exclusion, override setSynchronizationObject()
 * and make sure that you create an instance of ExclusiveZone at the
 * beginning of each method.
 *
 * \see Test, TestListener, TestResultCollector, Outputter.
