Next.js , TypeScript , React環境でjestでコンポーネントのテストがsyntaxErroeで通らない

Question

現在Next.js , TypeScript , Reactという環境で、
jestによるテストを導入しようと思っています。
が、コンポーネントのsnapshotのテストを行おうとするとsyntaxEllorが出ます。

jestの導入手順

1.npm install enzyme enzyme-adapter-react-16

２.setupTest.jsに記述
import Enzyme from "enzyme";
import Adapter from "enzyme-adapter-react-16";

Enzyme.configure({ adapter: new Adapter() });




3.npm install --save-dev enzyme-to-json
4.npm install --save @types/jest

下記のようなテストは通ります。

//__tests__/index.test.js

it("adds 1 + 2 to equal 3", () => {
    expect(sum).toBe(3);
  });

しかし、コンポーネントを含んだ下記のテストはエラーが出ます。

//__tests__/index.test.js


import React from "react";
import SideBar from "../components/cms/SideBar";
import { shallow } from "enzyme";
import toJson from "enzyme-to-json";


describe("<SideBar />", () => {
  it("<SideBar>", () => {
    const wrapper = shallow(<Aaaa />);
    expect(toJson(wrapper)).toMatchSnapshot();
  });
});

Jest encountered an unexpected token

    This usually means that you are trying to import a file which Jest cannot parse, e.g. it's not plain JavaScript.

    By default, if Jest sees a Babel config, it will use that to transform your files, ignoring "node_modules".

    Here's what you can do:
     • To have some of your "node_modules" files transformed, you can specify a custom "transformIgnorePatterns" in your config.
     • If you need a custom transformation specify a "transform" option in your config.
     • If you simply want to mock your non-JS modules (e.g. binary assets) you can stub them out with the "moduleNameMapper" config option.

    You'll find more details and examples of these config options in the docs:
    https://jestjs.io/docs/en/configuration.html
