how to mock moment() in jest?

[alirezahmz]

i'm using moment-jalaali": "^0.9.4",
i get this error when i try to run test : moment is not a function
and after google it, i found this code:
jest.mock('moment', () => ({
format: () => '2018–01–30T12:34:56+00:00'
}));
and run again
get this error: TypeError: moment.localeData is not a function
