Question 117783 in Mongodb Question posted in
The official documentation can be found here.

Error: Jest: Got error running globalSetup ../@shelf/jest-mongodb/setup.js, reason: Instance Exited before being ready and without throwing an error

I’m following the documentation on jestjs.io. When I try to run a test I get this error:

Error: Jest: Got error running globalSetup - /home/.../node_modules/@shelf/jest-mongodb/setup.js, reason: Instance Exited before being ready and without throwing an error!

This happened both when I’ve used typescript and also when I created a simple app using javascript instead:

package.json:

{
  "name": "mongojest",
  "version": "1.0.0",
  "main": "index.js",
  "license": "MIT",
  "devDependencies": {
    "@shelf/jest-mongodb": "^3.0.1"
  },
  "scripts": {
    "test": "jest"
  },
  "dependencies": {
    "jest": "^28.1.0"
  }
}

jest.config.js:

module.exports = {
  coverageProvider: "v8",
  "preset": "@shelf/jest-mongodb"
};

I haven’t made any changes other than the minimum installs to get it running.

    I got around this issue by installing Ubuntu 20.04. I was using the newer Ubuntu 22.04 and it seem to have caused some issues.
