jest hangs indefinitely with yarn pnp

Just getting started with yarn v3 but hit a bit of a problem with jest not running they just hang indefinitely with no output at all.

Recreation steps

yarn set version berry

yarn init

yarn add -D jest

yarn jest

// package.json
{
  "name": "yarn-again",
  "packageManager": "yarn@3.2.0",
  "devDependencies": {
    "jest": "^28.1.0"
  }
}

Anyone seen this before?

Solution

  • Bump node to 16.14.2 or upper or try to run yarn jest --runInBand and check errors
