Question

这是我的第一个带有SSR的Nextjs项目。

集成用于Reactjs UI测试的酶时。 “ React”是指UMD全局文件，但当前文件是一个模块。请考虑添加导入。”

但是当我使用普通的Reactjs Component（Functional或Class）时它是可行的。任何人都可以提出建议。

运行测试使用“ npm测试”

页面/Index.tsx

import Head from 'next/head'
import Link from 'next/link'
import { GetStaticProps } from 'next'

export default function Home({
  allPostsData
}: {
  allPostsData: {
    title: string
    id: string
  }[]
}) {
  return (
    <>
      <Head>
        <title>Sample Page</title>
      </Head>
      
      <section className="icon-stars">
        <p>[Your Self Introduction]</p>
        <p>
          (This is a sample website - you’ll be building a site like...)
        </p>
      </section>
      <section>
        <h2>Blog</h2>
        <ul>
          {allPostsData.map(({ id, title }) => (
            <li key={id}>
              <Link href="#">
                <a>{title}</a>
              </Link>
              <br />
            </li>
          ))}
        </ul>
      </section>
    </>
  )
}

export const getStaticProps: GetStaticProps = async () => {
  const allPostsData = [{id: 0, title:"Sample1"}, {id: 1, title:"Sample2"}]
  return {
    props: {
      allPostsData
    }
  }
}

_ 测试 _ / Index.tsx

import * as React from 'react'
import { expect as expect1 } from 'chai';

import IndexPage from '../pages/index'

import {/*mount,*/ shallow} from 'enzyme' 

const setUp1 = (data) => {
  return shallow(<IndexPage {...data} />);
}
let wrapper;

describe('props Check', () => {

  beforeEach(() => {
      wrapper = setUp1({});
  });

  it('should render an `.icon-stars`', () => {
    expect1(wrapper.find('.icon-stars')).to.have.length(1);
  });

});

当我使用上述代码时，由于出现以下错误而无法运行。

测试 /Index.tsx

import * as React from 'react'
import { expect as expect1 } from 'chai';

import IndexPage from '../pages/index'

import {/*mount,*/ shallow} from 'enzyme' 

const setUp1 = (data) => {
  return shallow(<IndexPage {...data} />);
}
let wrapper;

describe('props Check', () => {

  beforeEach(() => {
      wrapper = setUp1(allPostsData={[]});
  });

  it('should render an `.icon-stars`', () => {
    expect1(wrapper.find('.icon-stars')).to.have.length(1);
  });

});

您必须在测试组件内部传递道具并使用

import * as React from 'react'

在 pages / Index.tsx 中呈现反应组件

是否可以在Next js（SSR）中使用酶测试？
