如何在redux-sagas中进行测试？

import { put, call } from 'redux-saga/effects';
import { exampleSaga } from './exampleSaga';
import { exampleAction } from './exampleActions';
import { fetchData } from './api';

describe('exampleSaga', () => {
  it('should fetch data and dispatch success action', () => {
    const generator = exampleSaga();
    const data = { /* mock data */ };
    
    expect(generator.next().value).toEqual(call(fetchData));
    expect(generator.next(data).value).toEqual(put(exampleAction.success(data)));
    expect(generator.next().done).toBeTruthy();
  });
});

$ jest example.test.js
