Configure jest timeout once for all tests

Question

According to the docs one can increase the default async timeout from 5000ms using the jest-object

More specifically, by using the jestsettimeouttimeout

The issue I am facing is I am running a series of tests against an API that is very slow, 5-15 second response times, configuring this jest object at the top of each test is painfully annoying.

Is it possible to declare these settings once before all test files are run?

Jest offers a testTimeout configuration option you can add to your package.json:

  "jest": {
    "testTimeout": 15000,
  }

Hack!. You need to delete comma when single object has been. – Baris Senyerli Jan 27 '23 at 15:45

OK, putting bits together:

The Jest search box doesn't actually return anything when you search for: setupFilesAfterEnv

And docs talk about: setupTestFrameworkScriptFile (which also doesn't return anything on the search:/ )

Anyway, the docs leave you scratching your head but this works:

jest.config.js:

module.exports = {
  setupFilesAfterEnv: ['./setup.js'],

setup.js:

jest.setTimeout(10000); // in milliseconds

The jest folks should make it easier to find this information.

If someone stumbles across this post. The jest folks added a new config option called [`testTimeout`](https://jestjs.io/docs/en/configuration#testtimeout-number) which would do the same. :) — lumio, Jan 25 '21 at 16:18

Use testTimeout. In yourjest.config.js (or similar), add the following:

const SECONDS = 1000;

module.exports = {
  testTimeout: 60 * SECONDS
}

If you are working with react and initializing you app using create-react-app, then under your src/ directory you should have a file named setupTests.js. Here you can setup a global timeout for all of your tests just by insert this line after the import statement for @testing-libary

jest.setTimeout(15000); // in milliseconds
