如何在saga中测试firebase函数？

import { call, put, takeEvery } from 'redux-saga/effects';
import { firebaseFunction } from './firebaseFunctions';

export function* firebaseSaga(action) {
  try {
    const result = yield call(firebaseFunction, action.payload);
    yield put({ type: 'FIREBASE_SUCCESS', payload: result });
  } catch (error) {
    yield put({ type: 'FIREBASE_ERROR', payload: error });
  }
}

export function* watchFirebaseSaga() {
  yield takeEvery('FIREBASE_REQUEST', firebaseSaga);
}

import { call, put } from 'redux-saga/effects';
import { expectSaga } from 'redux-saga-test-plan';
import { firebaseSaga } from './saga';
import { firebaseFunction } from './firebaseFunctions';

describe('Firebase Saga', () => {
  it('should handle successful Firebase request', () => {
    const action = { type: 'FIREBASE_REQUEST', payload: 'data' };
    const result = 'success';

    return expectSaga(firebaseSaga, action)
      .provide([[call(firebaseFunction, 'data'), result]])
      .put({ type: 'FIREBASE_SUCCESS', payload: result })
      .run();
  });

  it('should handle failed Firebase request', () => {
    const action = { type: 'FIREBASE_REQUEST', payload: 'data' };
    const error = new Error('Request failed');

    return expectSaga(firebaseSaga, action)
      .provide([[call(firebaseFunction, 'data'), throwError(error)]])
      .put({ type: 'FIREBASE_ERROR', payload: error })
      .run();
  });
});
