Error running jest test

[Kurund Jalmi]

Hello,

I am getting the following error while running the test suite. UI works fine without any issues.

  ● Test suite failed to run

    Cookie has domain set to the public suffix "localhost" which is a special use domain. To allow this, configure your CookieJar with {allowSpecialUseDomain:true, rejectPublicSuffixes: false}.

Any thoughts how to fix this?

As a workaround you could try to add custom testURL property to jest configuration.

Example using jest configuration in package.json
"jest": { "testURL": "https://jestjs.io" }

Thank you. This fixes the test failure.

I tried without any luck (jest 27)

/** @type {import('@jest/types').Config.InitialOptions} */
module.exports = {
  preset: 'jest-expo',
  rootDir: '../../',
  testURL: 'http://localhost:3001',
  setupFilesAfterEnv: ['./test/jest/setup.js'], 

(also tried using https://jestjs.io just in case that does some 🪄)

testEnvironmentOptions: { url: "https://jestjs.io", },

worked for me (jest 29)

Please try with our latest release, we have updated our treatment of single word domains for localhost and invalid per RFC 6761: https://www.rfc-editor.org/rfc/rfc6761.html

This should be fixed in 4.1.2. Please let us know if you see any more issues.

Thank you. I can confirm that it's fixed for me.
