-"""Unit test for Google Test's break-on-failure mode.
-
-A user can ask Google Test to seg-fault when an assertion fails, using
-either the GTEST_BREAK_ON_FAILURE environment variable or the
---gtest_break_on_failure flag.  This script tests such functionality
-by invoking gtest_break_on_failure_unittest_ (a program written with
-Google Test) with different environments and command line flags.
