I was having the same issue. Used this in package.json file.. package.json

Earlier, I was setting timeout in beforeEach() function. Setting timeout in packgage.json solved the issue

beforeEach(() => {
  jest.useFakeTimers(); // you must add this
  fixture = TestBed.createComponent(HeaderComponent);
  component = fixture.componentInstance;
  fixture.detectChanges();
});
    
describe('test', () => {
  it('should call spy', (() => {
    const spy = jest.spyOn(storeFacade, 'notReadNotifications');
    const time = component["timeToCheckNotifications"] * 2 + 1
    jest.advanceTimersByTime(time);
    expect(spy).toHaveBeenCalledTimes(2);
// this is the test of function used the timer like (setInterval)
  }));
});
    
afterEach(() => {
  jest.runOnlyPendingTimers() // you must add this
  jest.useRealTimers() // you must add this
})
      
// here you can add others describe

I had the same issue and I solved it without editing the config file. What I did is, I added as a second argument a new timeOut as you can see below:

afterAll(async () => {
// your code here 
// your code here 
}, 100000)

I had the same issue, and as Cody mentioned, by increasing the "testTimeout" in my Jest config file, I managed to overcome this error.

Hope this helps other people encountering this error, thank you very much

My config file:

{
  "moduleFileExtensions": ["js", "json", "ts"],
  "rootDir": ".",
  "testEnvironment": "node",
  "testRegex": ".e2e-spec.ts$",
  "transform": {
    "^.+\\.(t|j)s$": "ts-jest"
  },
  "verbose": true,
  "testTimeout": 1000000
}

The timeout is referring to the the test taking longer than 5000 ms.

You can set the test timeout programmatically although I don't think this can be done within a test (as you've shown above) it would need to be done in a global setup file like jest.setup.js

Alternateively, I would suggest setting the timeout in your jest.config.js

example:

{
  "name": "my-project",
  "jest": {
    "verbose": true,
    "testTimeout": 5000
  }
}
