Solvedaphrodite Aphrodite + Jest error

I'm running an App that uses Aphrodite and Jest. After the test succeed, I get this error, related to Aphrodite:

        styleTag = document.querySelector("style[data-aphrodite]");

@green-arrow: I was able to solve this problem by returning a promise in the afterEach function:

afterEach(() => {
  return new Promise(resolve => {
    return process.nextTick(resolve);

still ran into the issue, with React 16.3.2, Jest 22.4.3, Aphrodite 2.2.0
via @saltycrane, found a perhaps cleaner solution here

here it is adapted to ES6, jestSetup.js:

import Enzyme from 'enzyme';
import Adapter from 'enzyme-adapter-react-16';
import * as Aphrodite from 'aphrodite';
import * as AphroditeNoImportant from 'aphrodite/no-important';


Enzyme.configure({ adapter: new Adapter() });

then reference it in your package.json:

"jest": {
  "setupTestFrameworkScriptFile": "<rootDir>/jestSetup.js"

Using jest.runAllTimers() didn't work for me. Importing StyleSheetTestUtils and adding StyleSheetTestUtils.suppressStyleInjection() on beforeEach and StyleSheetTestUtils.clearBufferAndResumeStyleInjection() on afterEach worked fine.

@mrchess You should be able to add this in each test:

beforeEach(() => {
afterEach(() => {

But if you really want to use timers (and you shouldn't), you can add this into your Jest configuration:

"timers": "fake"

Try adding jest.runAllTimers() at the end of your test?
