Jest + Supertest + Restify not working

[ravilution]

node 5.4.1 jest-cli ^12.0.2 restify ^4.0.4 supertest ^1.2.0

I want to use Jest to do backend nodejs REST API testing also. I do not want to install another test tool like mocha etc.

'use strict';
var request = require('supertest')(require('../appServer'));
describe('Test', function () {
    it('works', function () {
        request
            .get('/api')
            .expect(200)
            .end(function (err, res) {
                expect(err).toEqual(null);
            });
    });
});

In above code appServer returns a restify server instance. I am using supertest because I want to do code coverage as well. But I get below error.

Error: Cannot find module '_http_common' from 'stream.js'

Thank you for reporting this issue. Do you use mocking or is mocking disabled? If you'd like to test your modules/components "supertest" and "appServer" you'll have to unmock them first:

jest.unmock('supertest').unmock('../appServer');

Oops, wrong button, reopening :)

If you can't figure it out, can you provide a repository that points this issue out so I can take a closer look? Thank you :)

I have automock turned off. I also tried you unmock code. I also tried jest.disableAutomock();. Nothing works. Below is my jest config in package.json

  "jest": {
    "automock": false,
    "bail": true,
    "collectCoverage": true,
    "moduleFileExtensions": [
      "js"
    ],
    "scriptPreprocessor": "./node_modules/babel-jest",
    "testFileExtensions": [
      "js"
    ],
    "testPathDirs": [
      "./client/src",
      "./server"
    ],
    "testPathIgnorePatterns": [
      "/node_modules/",
      "/client/build/",
      "/docs/",
      "/logs/",
      "/coverage/"
    ]
  }

@cpojer Have you reopened? It still says closed.

[cpojer]

I boarded a long distance flight and my internet was cut-off before I could reopen this issue.

[ravilution]

@cpojer Any updates?

[cpojer]

No, you haven't provided a full repository that highlights this problem so there is no way for me to confirm your issue.

Below is the code. I did not want to create a repo for two files. Please try and let me know

var app = restify.createServer();

app.get('/user', function (req, res) {
  res.status(200).json({ name: 'tobi' });

var request = require('supertest')(app);

I think this should be fixed by setting the "testEnvironment" config option to "node". jsdom doesn't deal well with this stuff.

I ran over this issue today and here is how I deal with it. package.json:

...
"jest": {
    "testEnvironment": "node",
    "testPathIgnorePatterns": [
      "/node_modules/",
      "/dist/"
    ]
  }
...

__tests__/index.test.js:

import server from '../src/index.js';
import request from 'supertest';

afterEach(() => {
    server.close();
});

describe('Restify', () => {
    test('index route should return 200', (done) => {
        request(server)
            .get('/')
            .expect(200, done)
    });
});

I think the key is to pass done to the callback
