"""Unit test for Google Test's global test environment behavior.

A user can specify a global test environment via
|
|
testing::AddGlobalTestEnvironment. Failures in the global environment should
|
|
result in all unit tests being skipped.
|
|
|
|
This script tests such functionality by invoking
|
|
googletest-global-environment-unittest_ (a program written with Google Test).
