jest: Jest Progress bar and live stats not showing up when running in band

🐛 Bug Report

When I run jest, I don’t see the green progress bar or any of the live printout data in my terminal. The Test Suites, Tests, Snapshots, and Time stats are only printed out after all my tests are complete. Until tests are complete, the only indicator I see is:

RUNS path/to/tests

There’s no way for me to tell whether the tests have stalled or are still running until the entire suite is complete.

I am running jest with puppeteer for end to end testing.

To Reproduce

1. Clone the repo here: https://github.com/jeremygottfried/test-jest-cli
2. Run yarn install
3. Run yarn test (I set up jest global setup/teardown scripts to handle starting the server)

Test Code

import puppeteer from 'puppeteer';

describe('a basic react app that puppeteer can automate', () => {
  let browser;
  let page;

  beforeAll(async () => {
    browser = await puppeteer.launch({ slowMo: 250 });
    page = await browser.newPage();
  });

  afterAll(async () => {
    await browser.close();
  })

  it('opens the home page', async () => {
    await page.goto('http://localhost:3000');
    expect(await page.url()).toBe('http://localhost:3000/');
  })

  it('has app header', async () => {
    expect(await page.$('.App-header')).not.toBe(null);
  })

  it('has logo', async () => {
    expect(await page.$('img[src="/static/media/logo.5d5d9eef.svg"]')).not.toBe(null);
  })

  it('should have a Learn React link that opens a new page', async () => {
    await page.click('.App-link');
    expect(await page.url()).toBe('https://reactjs.org/')
  })
})

Global Setup Code

import spawnd from 'spawnd';
import cwd from 'cwd';
import http from 'http';

function serverReady() {
  return new Promise(function(resolve) {
    async function checkReady() {
      const req = http.get({
        hostname: 'localhost',
        port: 3000,
        path: '/',
      }, function (res) {
        if (res.statusCode === 200) {
          resolve();
        } else {
          return checkReady();
        }
      });
      req.on('error', function() {
        return checkReady();
      });
    }
    checkReady();
  });
}

export default async function setup() {
  console.log(`\nStarting up react server at port 3000...`);
  const server = spawnd('yarn', ['start'], { shell: true, cwd: cwd() });
  global.server = server;
  await serverReady();
  console.log('\nServer Ready');
}

Expected behavior

I expected my jest tests to show progress bar and live stats printouts like this:
