我知道“动作必须是简单的对象。对于异步动作,请使用自定义中间件。”已经被问了很多遍了,但是我找不到解决方法。
仅在酶测试中出现问题。
这是我的componentDidMount,它记录响应:
componentDidMount () {
this.props.dispatch(fetchUsers())
.then(response => console.log(response))
}
日志响应:用户:(27)[{…},{…},{…},{…},{…},{…},{…},{…},{…},{… },{…},{…},{…},{…},{…},{…},{…},{…},{…},{…},{…},{…}, {…},{…},{…},{…},{…}] 类型:“ GET_USERS_SUCCESS”
这是我的行动
export const fetchUsers = () => (dispatch) => {
dispatch(fetchUSersRequest())
const request = axios({
method: 'GET',
url: `${BASE_URL}users.json`,
headers: []
})
return request.then(
response => dispatch(fetchUsersSuccess(response.data)),
err => dispatch(fetchUsersError(err))
)
}
该组件是连接的组件。这是测试
import React from 'react'
import configureMockStore from 'redux-mock-store'
import { shallow } from 'enzyme'
import Users from './'
import * as mocks from '../../mocks/users'
const mockStore = configureMockStore();
describe('it works', () => {
const store = mockStore({});
const wrapper = shallow(<Users store={store} users={mocks.getUsersMock} filters={mocks.getFiltersMock} />).dive().dive()
console.log(wrapper.debug())
it("renders a div", () => {
expect(wrapper.find('div').length).toBe(1)
})
});
然后错误出在单元测试输出中
●有效›遇到声明异常
Actions must be plain objects. Use custom middleware for async actions.

我已经在使用redux-thunk
答案 0 :(得分:1)
尝试向redux-thunk
注册redux-mock-store
中间件,以便测试了解您在实际商店中使用的异步中间件的使用情况:
import configureMockStore from 'redux-mock-store'
import thunk from 'redux-thunk'
const middlewares = [thunk]
const mockStore = configureStore(middlewares)
希望有帮助!
