  31 """Unit test for Google Test's --gtest_list_tests flag.
  32
  33 A user can ask Google Test to list all tests by specifying the
  34 --gtest_list_tests flag. If output is requested, via --gtest_output=xml
  35 or --gtest_output=json, the tests are listed, with extra information in the
  36 output file.
  37 This script tests such functionality by invoking gtest_list_output_unittest_
  38  (a program written with Google Test) the command line flags.
