GTEST死亡测试

Posted 2023-02-05 heihei36

auto func = []() 
    exit(1);
;

::testing::FLAGS_gtest_death_test_style = "threadsafe";

EXPECT_EXIT(func(), testing::ExitedWithCode(1), "");

若不加上::testing::FLAGS_gtest_death_test_style = "threadsafe";

UT会BLOCK，且会有如下警告信息：

[WARNING] googletest-release-1.10.0/googletest/src/gtest-death-test.cc:1122:: Death tests use fork(), which is unsafe particularly in a threaded context. For this test, Google Test detected 2 threads. See https://github.com/google/googletest/blob/master/googletest/docs/advanced.md#death-tests-and-threads for more explanation and suggested solutions, especially if this is the last message you see before your test times out.
