Config 'testTimeout' not working inside 'projects' config

🐛 Bug Report

The configuration testTimeout (https://jestjs.io/docs/en/configuration#testtimeout-number) does not work in projects (https://jestjs.io/docs/en/configuration#projects-arraystring--projectconfig)

To Reproduce

Use this config and write a test taking more than 1 ms.

module.exports = {
  projects: [
    {
      testEnvironment: 'node',
      testTimeout: 1,
    },
  ],
};

Expected behavior

I expect each it(), beforeEach() etc. to time out after 1 ms.

Note that if you move the testTimeout: 1, outside of the projects array the config does kick in. I.e. this works:

module.exports = {
  testTimeout: 1,
  projects: [
    {
      testEnvironment: 'node',
    },
  ],
};

Original implementation: https://github.com/facebook/jest/issues/6216

Link to repl or repo (highly encouraged)

const { promisify } = require('util');

const sleep = promisify(setTimeout);

describe('suite A', () => {
  it('1', async () => {
    await sleep(2000);
    expect(true).toBeTruthy();
  });
});

I don’t think this is fixed… We encountered the same issue on version 26.4.2.

see also https://github.com/facebook/jest/issues/9696, which suggests hoisting the testTimeout setting up a level out of the project config as a workaround (provided you’re OK with the same timeout across all test projects).
