// Tests Google Test's throw-on-failure mode with exceptions disabled.
//
// This program must be compiled with exceptions disabled.  It will be
// invoked by gtest_throw_on_failure_test.py, and is expected to exit
// with non-zero in the throw-on-failure mode or 0 otherwise.

#include "gtest/gtest.h"

#include <stdio.h>                      // for fflush, fprintf, NULL, etc.
#include <stdlib.h>                     // for exit
#include <exception>                    // for set_terminate

// This terminate handler aborts the program using exit() rather than abort().
// This avoids showing pop-ups on Windows systems and core dumps on Unix-like
// ones.

  // We want to ensure that people can use Google Test assertions in
  // other testing frameworks, as long as they initialize Google Test

  // use Google Test's constructs for defining and running tests
  // (e.g. TEST and RUN_ALL_TESTS) here.

  // In the throw-on-failure mode with exceptions disabled, this
  // assertion will cause the program to exit with a non-zero code.
