/* This header defines a convenience macro for use by pure test programs.
 * A pure test program cannot take any arguments since it must be fully
 * automatable.  If your program needs to use argv/argc, it may be doing
 * measurements not unit and/or regression testing.  On Host architectures
 * these programs needs to be named main and take dummy argc/argv args,
 * but on vxWorks and RTEMS they must be named as the test program.
 *
 * Use this macro as follows:
 *
 *     #include "testMain.h"
 *     #include "epicsUnitTest.h"
 *
 *     MAIN(myProgTest) {
 *         testPlan(...);
 *         testOk(...)
 *         return testDone();
 *     }
