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

Question

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

My tests look as follows:

describe("Profile Ta

You can also get timeout errors based on silly typos. e.g This seemingly innocuous mistake:

describe('Something', () => {
  it('Should do something', () => {
    expect(1).toEqual(1)
  })

  it('Should do nothing', something_that_does_not_exist => {
    expect(1).toEqual(1)
  })
})

Produces the following error:

FAIL src/TestNothing.spec.js (5.427s)
  ● Something › Should do nothing

    Timeout - Async callback was not invoked within the 5000ms timeout specified by jest.setTimeout.
      
      at node_modules/jest-jasmine2/build/queue_runner.js:68:21
      at Timeout.callback [as _onTimeout] (node_modules/jsdom/lib/jsdom/browser/Window.js:678:19)

Whilst the code sample posted doesn't suffer from this it might be a cause of failures elsewhere. Also note that I'm not setting a timeout for anything anywhere - either here or the config the 5000ms is just the default setting.
