// Run the test runner and dump a json file. Use this script to pass
// the json file and return a list of failing tests that can be copied
// to test262.status.
//
// Usage:
//
// Run the test runner to generate the results:
// $ tools/run-tests.py --gn test262 --json-test-results=tools/.test262-results.json
//
// Run this script to print the formatted results:
// $ node tools/test262-results-parser.js .test262-results.json
//
// Note: The json results file generated by the test runner should be
// in the tools/ directly, which is the same dir as this script.
