如何使用Jest在Redux-saga中测试RxDB？

import { runSaga } from 'redux-saga';
import { createStore, applyMiddleware } from 'redux';
import createSagaMiddleware from 'redux-saga';
import { rxdbReducer, rxdbSaga } from './yourRxDBModule';

describe('Redux-saga with RxDB', () => {
  it('should handle async operation', async () => {
    const sagaMiddleware = createSagaMiddleware();
    const store = createStore(rxdbReducer, applyMiddleware(sagaMiddleware));
    sagaMiddleware.run(rxdbSaga);

    // 模拟一个Redux action
    const action = { type: 'FETCH_DATA' };

    // 运行saga并等待其完成
    await runSaga(
      {
        dispatch: (action) => store.dispatch(action),
        getState: () => store.getState(),
      },
      rxdbSaga,
      action
    ).toPromise();

    // 断言期望的结果
    expect(store.getState().data).toEqual(expectedData);
  });
});
