TypeError: jest.restoreAllMocks is not a function

[jeff-lau]

Using the latest version of jest (21.2.1), calls to

jest.restoreAllMocks()

Is failing with

TypeError: jest.restoreAllMocks is not a function

This maybe inside a test, or inside the afterEach.
However, it seems to work inside an afterAll?

The problem seems to have been mentioned and supposedly resolved here:
#4436

However, I created a new app using create-react-app, added a jest.restoreAllMock in the test, and it fails with the same error.

Is anyone else hitting this problem?

I'm unable to reproduce this, can you give a snippet which reproduces?

Thank you for looking into this @SimenB

I updated app.test.js to the following:

afterEach(() => {
	jest.restoreAllMocks();
});

it('renders without crashing', () => {
  const div = document.createElement('div');
  ReactDOM.render(<App />, div);
});

If I change afterEach to afterAll, the test would pass.

I still cannot reproduce this... Are you sure you are on latest version of jest?

This is my repro case: https://gist.github.com/anonymous/7e1f26019551ec8acdb287c4cf89ce27

I get a warning from react because of missing raf (can be fixed by jest@test, but no issues either way), but the test passes and does not crash.

Closing until we can reproduce this. Happy to reopen if we can, of course 🙂

[jeff-lau]

thanks @SimenB.

Looks like you are right, at least for the create-react-app example.

The actual project where this is happening does seem to have the correct version though, so I will need to investigate this further.

thanks for your help.
