"""Runs a python script under an isolate
This script attempts to emulate the contract of gtest-style tests
invoked via recipes. The main contract is that the caller passes the
argument:
--isolated-script-test-output=[FILENAME]
json is written to that file in the format produced by
common.parse_common_test_results.
This script is intended to be the base command invoked by the isolate,
followed by a subsequent Python script."""
