/*
 * TestToolsTracker.h
 * ------------------
 * Purpose: Unit test framework for OpenMPT.
 * Notes  : Really basic functionality that relies on a debugger that catches
 *          exceptions and breaks right at the spot where it gets thrown.
 * Authors: OpenMPT Devs
 * The OpenMPT source code is released under the BSD license. Read LICENSE for more details.
