如何在开发Directus扩展时设置单元测试？

npm install directus-cli -g

directus extensions:create my-extension

cd my-extension

npm install --save-dev jest supertest

mkdir tests
touch tests/my-extension.test.js

const request = require('supertest');
const app = require('../index');

describe('My Extension', () => {
  it('should return a success message', async () => {
    const res = await request(app).get('/api/my-extension');
    expect(res.statusCode).toEqual(200);
    expect(res.body.message).toEqual('Success');
  });
});

"scripts": {
  "test": "jest"
}

npm test
