| 12 This script acts as an interface between the Chromium infrastructure and | |
| 13 gtest-parallel, renaming options and translating environment variables into | |
| 14 flags. Developers should execute gtest-parallel directly. | |
| 15 | |
| 16 In particular, this translates the GTEST_SHARD_INDEX and GTEST_TOTAL_SHARDS | |
| 17 environment variables to the --shard_index and --shard_count flags, and renames | |
| 18 the --isolated-script-test-output flag to --dump_json_test_results. | |
| 19 | |
| 20 Note that the flags unprocessed by this script will passed as arguments to the | |
| 21 test executable, i.e. | |
| 22 | |
| 23 gtest-parallel-wrapper.py some_test \ | |
| 24 --isolated-script-test-output=some_dir \ | |
| 25 --unprocessed_arg_1 | |
| 26 -- \ | |
| 27 --unprocessed_arg_2 | |
| 28 | |
| 29 will be converted into | |
| 30 | |
| 31 python gtest-parallel some_test \ | |
| 32 --shard_count 1 \ | |
| 33 --shard_index 0 \ | |
| 34 --dump_json_test_results some_dir \ | |
