|
| -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.
