### 背景

新建构是基于Ice.js搭建的，在写单元测试的时候遇到一些问题，此篇作为填坑记录。

一开始ice是不支持运行单元测试，因为暴露出来的ice是alias出来的虚包，所以直接在单元测试里import是没法运行的，遂到社区提了issue，前几天传来利好，有了alpha版本能支持写单元测试了，所以下面实践一把。



### 实操

#### **services**

测试services（ice框架）里的方法

比如：

```
import { request } from "ice";

const mockId = "00000000-0d00-0000-0000-000000000000";

export default {
  async fetchList(params, config={}) {
    return await request.post(
      "/api/v1/domain/getResourcesByDomainId",
      {
        ...params,
        id: mockId,
      },
      { ...config }
    );
  },
};
```

测试用例：

```
/**
 * @jest-environment node
 */

//@jest-environment node 表示测试环境你，默认为jsdom(类浏览器)，node表示为node服务的方式(测试跨域请求时需要用到)
import listService from '../../../../src/pages/ResourceCenter/services/list'
import getCookie from '../../../_helper/getCookie'

let headers = {}
beforeEach(async () => {
	const Cookie = await getCookie()
	headers = { Cookie }
})

describe('fetchList', () => {
	test('listService fetchList', async () => {
		const params = { pageNum: 1, pageSize: 10 }
		const config = {
			withCredentials: true,
			headers: { ...headers },
		}
		const data = await listService.fetchList(params, config)
		expect(data).not.toBeNull()
	})
})
```



#### 带store的组件



比如：

```
import React, { useEffect } from 'react';
import { Grid, Tab } from '@alifd/next';
import { store as pageStore } from 'ice/ResourceCenter';
import ResourceList from './components/list.jsx';
import styles from './index.module.scss';
import ResourceTypeTree from './components/tree.jsx';
import DetailConfig from './components/detail_config.jsx';

const { Row, Col } = Grid;

const AlarmAnalyze = () => {
  const [treeState, treeDispatchers] = pageStore.useModel('tree');
  const [listState, listDispatchers] = pageStore.useModel('list');
  useEffect(() => {
    treeDispatchers.fetchTree();
    listDispatchers.fetchList();
  }, []);

  return (
    <div>
      <Row>
        <Col span="4">
          <div className={styles['layout-aside']}>
            <ResourceTypeTree data={treeState.data} />
          </div>
        </Col>
        <Col span="20">
          <div className="layout-content">
            <Tab>
              <Tab.Item title="xxx" key="1">
                <ResourceList data={listState} />
              </Tab.Item>
              <Tab.Item title="xxx" key="2">
                <DetailConfig data={listState} />
              </Tab.Item>
            </Tab>
          </div>
        </Col>
      </Row>
    </div>
  );
};

export default AlarmAnalyze;
AlarmAnalyze.pageConfig={
  auth:["/resourceCenter"]
}
```

测试用例：

```
import React from 'react'
import AlarmAnalyze from '../../../src/pages/ResourceCenter/index'
import { store as pageStore } from 'ice/ResourceCenter'
import { shallow, mount } from 'enzyme'
//测试内容中需要处理store时，需要用provider包裹
const PageProvider = pageStore.Provider

const WithPageModel = (props) => {
	return (
		<PageProvider>
			<AlarmAnalyze {...props} />
		</PageProvider>
	)
}

let wrapper
beforeEach(() => {
	wrapper = mount(<WithPageModel />)
})

describe('render', () => {
	test('Test ResourceList  ', () => {
		const cwrapper = wrapper.find('ResourceList')
		expect(cwrapper.prop('data')).toEqual({ ciType: '', current: 1, keyword: '', list: [], pageSize: 10, total: 0 })
		//取消挂载
		wrapper.unmount()
	})

	test('Test pagination  ', () => {
		const pagination = wrapper.find('Pagination')
		expect(pagination.prop('total')).toBe(0)
		//取消挂载
		wrapper.unmount()
	})

	test('Test ResourceTypeTree  ', () => {
		const cwrapper = wrapper.find('ResourceTypeTree')
		expect(cwrapper.prop('data')).toEqual(expect.arrayContaining([]))
		//取消挂载
		wrapper.unmount()
	})
})

```



#### 命令

注意只能用icejs来运行，想想也是应该的，因为你要测的东西就是ice那一套的，不可能随便拽个Jest就能跑，Jest咋知道哪跟哪呢。

```
"icetest:watch": "icejs test --jest-watch",
"ice:coverage": "icejs test --jest-coverage",
```
