A test modifier which states that the test shall not dump core, no matter what happens.

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

Prevent the test process from dumping core. This can be useful in situations where a core dump is expected, for example when verifying that an assert(expr) traps.

	Note
	The NO_CORE_FILE modifier uses setrlimit(RLIMIT_CORE, 0) to prevent the core dump. Calling setrlimit(RLIMIT_CORE, n) inside a test defeats the purpose of the NO_CORE_FILE modifier.

	Tip
	EXPECT_SIGNAL_DEATH(signo) is useful together with NO_CORE_FILE to verify that assert(expr) traps.

Example: The test program

     
     #include <crpcut.hpp>
     
     extern "C"
     {
     #include <signal.h>
     }
     
     TEST(pass_sigabort, EXPECT_SIGNAL_DEATH(SIGABRT), NO_CORE_FILE)
     {
       abort();
     }
     
     TEST(fail_with_core_dump, EXPECT_SIGNAL_DEATH(SIGABRT))
     {
       abort();
     }
     
     
     int main(int argc, char *argv[])
     {
       return crpcut::run(argc, argv);
     }

reports one failed test, due to a left-behind core file:

     FAILED: fail_with_core_dump
