gtest how to stop all running threads

Question

If I have a test case as follows

TEST(one, test_one) {
    vector<thread> threads
    // ... initialize threads
}

and somewhere in those threads an assertion fails, how do I stop all threads and terminate? because it seems like the function keeps executing as of now..

Oh boy, that completely depends on how you synchronized your threads with any _runnable_ condition. — πάντα ῥεῖ, Jul 07 '16 at 00:14
Something within the lines of [Death Tests](http://stackoverflow.com/questions/3698718/what-are-google-test-death-tests) maybe. — πάντα ῥεῖ, Jul 07 '16 at 00:16

It can't be done without interactions from your class under test, and the threads it involves actually.

If you have some class under test, that involves running multiple threads, you should have some implementation in the destructor, to signal threads to stop and join them.

Though I could think about something along the lines of a death test bailing out from an expected assert() statement, and the whole process is killed (hence no need to worry about other threads being terminated).
