setupFiles can't be found when using browser-resolve Jest resolver

[vvanmol]

🐛 Bug Report

I just upgraded all of our testing libraries to their latest version, including Jest.
Our test suite was dependant on the Jest configuration browser field which had been deprecated now.

I followed the instructions on how to reproduce the behaviour of that browser configuration field and added the following to my Jest configuration file:

"resolver": "browser-resolve"

Since then, when I run our test suite, it directly fails because Jest can't find a local setupFile defined as follow:

"setupFiles": [
    "<rootDir>/test/setup.js"
]

It fails with the following error:

Validation Error:

  Module <rootDir>/test/setup.js in the setupFiles option was not found.
         <rootDir> is: /Users/path/to/application/root

While the displayed path is actually correct and points to my setup script.

To Reproduce

Here's my full Jest configuration file which should be enough to reproduce:

{
  "collectCoverage": true,
  "collectCoverageFrom": [ "src/**/*.{js,jsx}" ],
  "coverageDirectory": "public/coverage/",
  "moduleFileExtensions": ["js", "json", "jsx", "yaml"],
  "moduleNameMapper": {
    "\\.scss$": "identity-obj-proxy"
  },
  "resolver": "browser-resolve",
  "setupFiles": [
    "<rootDir>/test/setup.js"
  ],
  "transform": {
    "\\.yaml$": "yaml-jest",
    "\\.jsx?$": "babel-jest"
  },
  "testResultsProcessor": "jest-sonar-reporter",
  "testURL": "http://localhost:8080/my-application",
  "verbose": true
}

Expected behavior

Local setup files should be resolved properly.

Any update on this? I'm having the same bug.

Jest 26.6.3 with Node.js v15.10.0 on Ubuntu 20.10

Without the setupFiles option, this is also affecting node_modules packages:

Module /home/piranna/github/randomUUID/node_modules/jest-jasmine2/build/index.js in the testRunner option was not found.
         <rootDir> is: /home/piranna/github/randomUUID

Seems like the resolver option is plainly broken.

Any update on this? How can we move it forward?

The example was wrong, sorry. I updated it in #11140. See updated docs: https://jestjs.io/docs/configuration#resolver-string
