// The EXPECT_DFATAL and ASSERT_DFATAL macros are lightweight
// alternatives to EXPECT_DEBUG_DEATH and ASSERT_DEBUG_DEATH. They
// are appropriate for testing that your code logs a message at the
// DFATAL level.
//
// Unlike EXPECT_DEBUG_DEATH and ASSERT_DEBUG_DEATH, these macros
// execute the given statement in the current process, not a forked
// one. This works because we disable exiting the program for
// LOG(DFATAL). This makes the tests run more quickly.
//
// The _WITH() variants allow one to specify any matcher for the
// DFATAL log message, whereas the other variants assume a regex.
