A test modifier which states that the normal way to finish the test is via exit() instead of returning from the function.

Used in: The modifier list of a test. See TEST(name, ...)

The parameter to EXPECT_EXIT(num) is the exit code, or ANY_CODE if any exit code is accepted.

If the test finishes through any other means, it fails.

	Note
	EXPECT_EXIT(num) cannot be used together with either of EXPECT_EXCEPTION(type) or EXPECT_SIGNAL_DEATH(signo).

Example: The test program

     
     #include <crpcut.hpp>
     
     TEST(fail_no_exit, EXPECT_EXIT(ANY_CODE))
     {
     }
     
     TEST(pass_any_code, EXPECT_EXIT(ANY_CODE))
     {
       exit(3);
     }
     
     TEST(fail_wrong_code, EXPECT_EXIT(3))
     {
       exit(0);
     }
     
     TEST(pass_correct_code, EXPECT_EXIT(3))
     {
       exit(3);
     }
     
     TEST(fail_by_exception, EXPECT_EXIT(ANY_CODE))
     {
       throw std::bad_alloc();
     }
     
     int main(int argc, char *argv[])
     {
       return crpcut::run(argc, argv);
     }

reports three failed tests:
