/**
 * @file   testGlobalTriggerComponent.C
 * @author Artur Szostak <artursz@iafrica.com>
 * @date   19 Dec 2008
 *
 * This macro is used to test the AliHLTGlobalTriggerComponent class.
 * A number of tests are run with the AliHLTSystem framework to check that
 * the automatically generated global trigger logic is generated correctly.
 *
 * This macro can also be used to debug the configuration that fails.
 * If a configuration test fails then the global trigger logic implementation
 * is left in a generated file with a name of the form \<AliHLTGlobalTriggerImpl_*.cxx\>.
 * For example a file named like: AliHLTGlobalTriggerImpl_08869e64_c54b_11de_9717_0101007fbeef.cxx
 * One can make manual modifications to this file and then rerun the test with
 * these manual modifications with the following command in aliroot:
 *  .x testGlobalTriggerComponent.C+(\<configVersion\>,"\<AliHLTGlobalTriggerImpl_*\>")
 * where \<configVersion\> is the appropriate config version number as passed to the
 * TriggerConfig.C file to initialise the configuration we want to test. Also take note
 * that we only specify the root of the file name without the .cxx file name extention.
 * For our example file name the command to execute in aliroot would be:
 *  .x testGlobalTriggerComponent.C+(2,"AliHLTGlobalTriggerImpl_08869e64_c54b_11de_9717_0101007fbeef")
 * where we are testing the 2nd trigger configuration in TriggerConfig.C.
