Jest + Dotenv - Doesn't load env variables using "setupFilesAfterEnv" (ignored?)

It looks like setupFilesAfterEnv in package.json is either ignored or misconfigured doc

  "jest": {
    "setupFilesAfterEnv": [
      "./jest-preload-env.js",
      "jest-extended"
    ],
    "verbose": true
  },

My file ./jest-preload-env.js contains the following:

require('dotenv').config({ path: '.serverless/.env' });

if (process.env.NODE_ENV !== 'test') {
  throw Error('Non-test environment');
}

But adding console.log there doesn’t seem to be executed. This breaks my tests, as ENV variables aren’t loaded before tests are executed.

I’m running serverless-bundle test --watchAll --runInBand, which seems to call jest (through , but after looking at the source, I believe the setupFilesAfterEnv is ignored by the plugin.

jest.config.js

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

jest.setup.js

require('dotenv').config({
  path: './.env',
});

setupFilesAfterEnv works fine and fixed my tests! 💯
