"""
This script acts as an interface between the Chromium infrastructure and
gtest-parallel, renaming options and translating environment variables into
flags. Developers should execute gtest-parallel directly.
In particular, this translates the GTEST_SHARD_INDEX and GTEST_TOTAL_SHARDS
environment variables to the --shard_index and --shard_count flags, and renames
the --isolated-script-test-output flag to --dump_json_test_results.
Note that the flags unprocessed by this script will passed as arguments to the
test executable, i.e.
gtest-parallel-wrapper.py some_test \
--isolated-script-test-output=some_dir \
--unprocessed_arg_1
-- \
--unprocessed_arg_2
will be converted into
python gtest-parallel some_test \
--shard_count 1 \
--shard_index 0 \
--dump_json_test_results some_dir \
-- \
--unprocessed_arg_1
--unprocessed_arg_2
