Error: Invariant Violation: Store.__emitChange(): Must be invoked while dispatching

I'm trying to test flux stores. I use ReduceStore from flux/utils, jest v0.7.0. When I dispatch an action with the mocked dispatcher I get an error:

Error: Invariant Violation: Store.__emitChange(): Must be invoked while dispatching.

If I use this store in a real browser, it works as expected.

Here is my store:

import {ReduceStore} from 'flux/utils';
import Immutable from 'immutable';
import Dispatcher from '../dispatcher';
import actionConstants from '../action-constants';

class EntryStore extends ReduceStore {

  getInitialState() {
    return Immutable.List();
  }

  reduce(state, action) {
    switch (action.type) {
      case actionConstants.ENTRIES_REQUEST_SUCCESS:
        return state.merge(action.payload.entries);

      default:
        return state;
    }
  }

}

const instance = new EntryStore(Dispatcher);
export default instance;

And, here is a test file:

jest.autoMockOff();
jest.mock('../../dispatcher');
const actionConstants = require('../../action-constants');    

describe('EntryStore', function() {

  let Dispatcher, EntryStore, callback;

  // mock entries
  entries = [1, 2, 3];
  // mock actions
  const Immutable = require('immutable');
  const entriesRequestSuccess = {
    type: actionConstants.ENTRIES_REQUEST_SUCCESS,
    payload: {
      entries: Immutable.List(entries)
    }
  }

  beforeEach(function() {
    Dispatcher = require('../../dispatcher');
    EntryStore = require('../entry-store');
    callback = Dispatcher.register.mock.calls[0][0];
  });

  it('should update entries when entries request succeed', function(done) {
    callback(entriesRequestSuccess);
    let all = EntryStore.getState();
    expect(all.size).toBe(3);
  });

});
