我正在使用ARc入门套件（https://github.com/diegohaz/arc）并尝试测试我的容器并出现此错误。
我有contianer：
import {connect} from 'react-redux';
import { addTodoRequest } from 'store/actions';
import { AddTodo } from 'components'
export const mapDispatchToProps = {
addTodo: addTodoRequest
}
export default connect(null, mapDispatchToProps)(AddTodo)
并测试它
import {mapDispatchToProps} from '../AddTodoContainer';
import { addTodoRequest } from 'store/actions';
describe('AddTodoContainer tests', () => {
it('mapDispatchToProps test', () => {
expect(mapDispatchToProps).toEqual({addTodo: addTodoRequest})
})
})
出现此错误：
