"Module * in the testRunner option was not found" when using "resolver": "browser-resolve"

[elado]

🐛 Bug Report

jest@26.1.0
browser-resolve@1.11.3

When setting "resolver": "browser-resolve", option, jest shows the following error:

● Validation Error:

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

  Configuration Documentation:
  https://jestjs.io/docs/configuration.html

<PATH>/node_modules/jest-jasmine2/build/index.js does exist.

To Reproduce

package.json:

{
  "dependencies": {
    "browser-resolve": "^1.11.3",
    "jest": "^26.1.0"
  },
  "jest": {
    "resolver": "browser-resolve"
  }
}

test.test.js:

test("x", () => {});

yarn jest

Tried also installing jest-circus and adding:

"testRunner": "jest-circus/runner"

and I'm getting

Module jest-circus/runner in the testRunner option was not found.

I guess it's related to recent deprecation of browser: https://github.com/facebook/jest/pull/9943/files

When I use the deprecated browser field, I'm getting a deprecation warning, but tests pass:

● Deprecation Warning:

  Option "browser" has been deprecated. Please install "browser-resolve" and use the "resolver" option in Jest configuration as follows:
  {
    "resolver": "browser-resolve"
  }

Expected behavior

No errors.

+1 Getting exactly the same issue.

I ran npm install jest-circus --save-dev, it's not installed by default.

I found that somehow, the testRunner path on my package.json was hardcoded with an absolut path (/Users/timgivois.....). I had to change it to

"testRunner": "<rootDir>/node_modules/jest-circus/runner.js",

And I had to install jest-circus, just like Sean said:

yarn add --dev jest-circus

[lukejagodzinski]

Did anyone solve it without installing jest-circus?

[amrtawfik160]

Try to remove node_modules and package-lock.json then run npm install or yarn << This solution worked for me

I just recently created a new React app using create-react-app and when I ejected, it did this.

I had to change the Jest testRunner configuration from /Users/devinriegle/code/projectName/node_modules/jest-circus/runner.js to <rootDir>/node_modules/jest-circus/runner.js

thank you, it's working now

[muhammedgaygisiz]

I had the same issue (hardcoded path). I just did an eject, probably it was because of that.

[filipe-costa]

/node_modules/jest-circus/runner.js

I was having the exact same issue when using Docker, this fixed it.

Thanks!

I had the same issue (hardcoded path). I just did an eject, probably it was because of that.

Same here, did an eject earlier which added the absolute path that broke everything.

Default export if browser-resolve is async, so you need a module in between (see docs).

Hard coded jest-circus is not related (but probably caused by ejecting CRA: facebook/create-react-app#9993)
