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.

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.

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 /tmp/crpcute5y8uO/fail_with_core_dump is not empty!! phase="running" -------------------------------------------------------------- Died with core dump ------------------------------------------------------------------------------- =============================================================================== Files remain under /tmp/crpcute5y8uO Total 2 test cases selected UNTESTED : 0 PASSED : 1 FAILED : 1
