Issues running cookie test code

I can’t seem to run the cookie test code.

Here’s my package.json

  "name": "realtimechat",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "dependencies": {
    "dropzone": "^5.9.2",
    "jest": "^27.0.3",
    "server": "^1.0.33"
  },
  "devDependencies": {
    "css-loader": "^5.2.6",
    "style-loader": "^2.0.0",
    "webpack-cli": "^4.7.0"
  },
  "scripts": {
    "start": "node index.js",
    "test": "jest --coverage --forceExit"
  },
  "repository": {
    "type": "git",
    "url": "git+https://github.com/dpaschal7/RealTimeChat.git"
  },
  "author": "",
  "license": "ISC",
  "bugs": {
    "url": "https://github.com/dpaschal7/RealTimeChat/issues"
  },
  "homepage": "https://github.com/dpaschal7/RealTimeChat#readme"
}

I keep getting a ReferenceError for run what other dependencies are missing

Thanks for opening an issue, certainly testing is well under-documented so I’ll try to explain the basics in this issue. I would not recommend using run at all for your own tests; it’s here for internal tests and definitely nowhere near stable. Instead, use some 3rd party testing library like supertest:

// index.js - Main project file
const server = require('server');
const { get } = server.router;

// Notice that we export the server here for testing later on:
module.exports = server(
  get('/user', () => ({ name: 'john' }))
);

Your test file (need to npm install supertest jest --save-dev first):

// index.test.js - API testing file
const request = require('supertest');

// The promise exported from your index
const serverPromise = require('./index.js');

// This will be populated after the server has launched. You can call it
// anything you want; server, runtime, ctx, instance, etc. are all valid names
let server;

describe('user', () => {
  // Populate it with the running instance when it's ready
  beforeAll(async () => {
    server = await serverPromise;
  });
  // Avoid leaving it hanging after all the tests have run
  afterAll(async () => {
    await server.close();
  });
  it('tests the user endpoint', async () => {
    await request(server.app)
      .get('/user')
      .expect('Content-Type', /json/)
      .expect('Content-Length', '15')
      .expect(200);
  });
});

Things become more difficult if you want to require() it from different files because then it’s launched multiple times with the same port (so it’ll fail). I recommend a single entry point like the above for testing for the API itself.

This seems to be fixed, or at least it’s been answered. Please feel free to reopen if you still have an issue here or to create a new issue asking more questions. Cheers!
