JEST-RUNTIME-CLI.JS(1)

💖 JEST-RUNTIME-CLI.JS(1) 💖

okay so first things first, bestie: this page lives in User Commands, section 1 of the manual, and the whole thing is called jest-runtime-cli.js. Yes, the file name literally ends in .js. We love a self-aware queen. 🎀

---

✨ NAME ✨

jest-runtime-cli.js — the Jest cli, but make it usable in a sandboxed Jest environment. it's giving "Jest inside Jest", inception-core, and honestly? iconic. 🦋

---

🌸 SYNOPSIS 🌸

jest-runtime-cli.js [--config=<pathToConfigFile>]

that's it. that's the whole vibe. one optional config path and she's ready. periodt. 💅

---

🎀 OPTIONS 🎀

• --cache — whether to use the preprocessor cache or not. want it OFF? hit her with --no-cache. it's a boolean and it defaults to true, so the cache is very much on unless you say otherwise. 🍓
• -c, --config — the path to a Jest config file. that's a string, no default, you bring your own. 💜
• --debug — prints debugging info about your jest config. pure boolean, no default listed, so it's just off until you want the tea. 🔥
• --watchman — whether to use watchman for file crawling. not feeling it? --no-watchman and she'll walk instead of run. boolean, and default is true. 👑
• -r, --replname — the "name" of the file that gets handed to transformers to be transformed. like, for example, "repl.ts" if you're rocking a TypeScript transformer. it's a string, no default. ✨

😭 AND THEN THIS JUST... SITS THERE

okay so lowkey the manpage then includes this raw chunk with zero further comment, and I'm not gonna lie to you, I'm just relaying it verbatim because it's literally part of the page:

triggerUncaughtException(err, true /* fromPromise */); ^

[??? Unrecognized CLI Parameter:

       Unrecognized option "version".

       CLI Options Documentation: https://jestjs.io/docs/cli

]

Node.js v24.19.0

bestie I am NOT going to speculate on what this means. it's in the page. it stays in the page. no cap. 💀

🫶 THE CUTE SIGN-OFF 🫶

so the footer tells us this page comes from jest-runtime-cli.js — version string node:inte... (yes, tragically truncated, we don't make the rules) — and it's dated September 2026, filed under JEST-RUNTIME-CLI.JS(1). 🌈

that's the whole page, bestie. you're now officially fluent. go forth and configure responsibly. mwah. 💅💖🌸
