c++ - In gtest, can you try/catch a function that calls "exit(1)"? -


there's function calls exit(1) specific cases, , i'm trying run unit tests gtest on function.

i thought i'd able use try/catch case function calls exit(1), doesn't catch me.

is normal behavior? if so, how else should detect exit(1) called?

unlike in, say, python, exit() function of c , c++ doesn't work throwing exception. once has done c runtime cleanup (e.g. calling registered atexit() handlers), directly calls kernel terminate process, , control never returns program.

the news that

google test support testing program exit:

assert_exit(statement, predicate, regex); , expect_exit(statement, predicate, regex);

statement exits given error , exit code matches predicate

i haven't checked, guess implemented fork()ing test, , waiting child terminate.
