-"""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. |
