// \brief  Macros for registering the tests with the driver.
//
// A test driver program would simply look like
// \verbatim
//   #include <testlib/testlib_register.h>
//   DECLARE( some_test_name );
//   void register_tests()
//   {
//     REGISTER( some_test_name );
//   }
//   DEFINE_MAIN;
// \endverbatim
// The DEFINE_MAIN macro will define the main() function for the driver.
// You will also have to link in a file defining a function
// \verbatim
//   int some_test_name_main(int,char*[])
// \endverbatim
// See the vxl tests for further examples (such as vil/tests).

#include <vcl_vector.h>
#include <vcl_string.h>

#if 0 // ifdef VCL_VC - gives compiler errors - PVr
typedef int ( (__cdecl *const) TestMainFunction)( int, char*[] );
#else
typedef int (*TestMainFunction)( int, char*[] );
#endif

extern vcl_vector<TestMainFunction> testlib_test_func_;
extern vcl_vector<vcl_string>       testlib_test_name_;


//: Declare the existence of the test.
// If you DECLARE( x ), then you will need to define a function int x_main(int,char*[]).
#ifdef VCL_VC
#define DECLARE( testname ) int _cdecl testname ## _main ( int argc, char* argv[] )
#else
#define DECLARE( testname )  int testname ## _main ( int argc, char* argv[] )
#endif

//: Register the test with the driver.
// \param testname should be the same as one of the tests declared with DECLARE.
#define REGISTER( testname ) \
   testlib_test_func_.push_back( & testname ## _main ); \
   testlib_test_name_.push_back( #testname )

//: Define the main() routine for this test driver.
// This allows the main function to be defined in the driver code
// itself--instead of in the testlib library--thus avoiding
// "awf-weirdness". This also means that functionality from the test
// library, such as testlib_root_dir, can be used even if it is not
// used to create a test driver.
