{"library":"test262-parser-runner","type":"library","category":null,"description":"The `test262-parser-runner` is a utility designed to execute the official ECMAScript Test Suite (Test262) against any given JavaScript parser. Currently at version 0.5.0, it targets early-stage development and parser validation. While it doesn't specify a fixed release cadence, its versioning suggests ongoing development with potentially frequent updates. A key differentiator is its robust mechanism for managing test outcomes: it supports a `skip` filter function to completely ignore tests (e.g., for unimplemented features) and a `whitelist` array for tests expected to fail temporarily but eventually pass. This allows parser developers to precisely control which tests contribute to their pass/fail metrics. The project distinguishes itself by building upon a previously MIT-licensed test runner while distributing its own code under the GNU Affero General Public License v3.0, a significant detail for downstream users.","language":"javascript","status":"active","version":"0.5.0","tags":["javascript","test262"],"last_verified":"Wed May 27","install":[{"cmd":"npm install test262-parser-runner","imports":["import run from 'test262-parser-runner';","const run = require('test262-parser-runner');","import { parse } from 'acorn';"]},{"cmd":"yarn add test262-parser-runner","imports":[]},{"cmd":"pnpm add test262-parser-runner","imports":[]}],"homepage":null,"github":"https://github.com/adrianheine/test262-parser-runner","docs":null,"changelog":null,"pypi":null,"npm":"https://www.npmjs.com/package/test262-parser-runner","openapi_spec":null,"status_page":null,"smithery":null,"compatibility":{"summary":{"python_range":"18–22","success_rate":0,"avg_install_s":null,"avg_import_s":null,"wheel_type":null},"url":"https://checklist.day/v1/registry/test262-parser-runner/compatibility"}}
