Message “Async callback was not invoked within the 5000 ms timeout specified by jest.setTimeout”

by

I’m using Puppeteer and Jest to run some front end tests.

My tests look as follows:

describe("Profile Tab Exists and Clickable: /settings/user", () => {
    test(`Assert that you can click the profile tab`, async () => {
      await page.waitForSelector(PROFILE.TAB);
      await page.click(PROFILE.TAB);
    }, 30000);
});

Sometimes, when I run the tests, everything works as expectedly. Other times, I get an error:

Timeout – Async callback was not invoked within the 5000 ms timeout specified by jest.setTimeout.

     at node_modules/jest-jasmine2/build/queue_runner.js:68:21 <br/>
     at Timeout.callback [as _onTimeout] (node_modules/jsdom/lib/jsdom/browser/Window.js:633:19)

This is strange because:

  1. I specified the timeout to be 30000

  2. Whether or not I get this error is seemingly very random

Why is this happening?
