Sentry jest mocking issue

[chintsan]

Hi, i am trying to mock sentry using jest. i have tried below. please let know what i need to do for mocking a constructor which is assigned to integrations.

import {Sentry} from '../../../mocks/sentry';

---

mocks/sentry.ts
const Sentry = {
init: jest.fn(),
integrations: tried various options but can't get how to assign a mock constructor,
};

export {Sentry};

jest.mock('@sentry/browser', () => ({
Sentry: {
init: jest.fn(),
integrations : ? (not sure how to assign a mock constructor which integrations is expecting)
}
}));

describe('Sentry should be initialised', () => {
...........
expect(Sentry.init).toHaveBeenCalled();
});

Expected - sentry should be called successfully in the tsx file where its initialised.
Actual - TypeError: _tracing.BrowserTracing is not a constructor

below is the sentry initialisation

Sentry.init({
dsn: <>,
integrations: [new BrowserTracing()],
tracesSampleRate: 1.0,
});

thank you. was able to resolve using jest.spyOn(Sentry, 'init').
