"""Unit test for Google Test's --gtest_list_tests flag.
A user can ask Google Test to list all tests by specifying the
--gtest_list_tests flag. If output is requested, via --gtest_output=xml
or --gtest_output=json, the tests are listed, with extra information in the
output file.
This script tests such functionality by invoking gtest_list_output_unittest_
