/*
 *  Contains Interface to Run tests.
 *
 *  Aug 2001      Initial implementation. (AK)
 *
 *  09/Aug/2001   Contains generic run tests interface which can be used
 *                for any type of frontend interface framework. (AK)
 *
 *  24/Nov/2001   Added Handler for Group Initialization failure condition. (AK)
 *
 *  05-Aug-2004   New interface.  Since these should be internal functions,
 *                no support for deprecated version 1 names provided now,
 *                eliminated global variables for current test & suite,
 *                moved (renamed) _TestResult here from TestDB.h. (JDS)
 *
 *  05-Sep-2004   Added internal test interface. (JDS)

/** @file
 *  Test run management functions (user interface).
 *  The TestRun module implements functions supporting the running
 *  of tests elements (suites and tests).  This includes functions for
 *  running suites and tests, retrieving the number of tests/suites run,
 *  and managing callbacks during the run process.
 *
 *  <P>The callback mechanism works as follows.  The CUnit runtime system
 *  supports the registering and calling of functions at the start and end
 *  of each test, when all tests are complete, and when a suite
 *  initialialization function returns an error.  This allows clients to
 *  perform actions associated with these events such as output formatting
 *  and reporting.</P>
