使用 Mocha 和 Chai GET 进行异步测试不适用于 Node.js Rest API

Question

Thanks in advance for reading!

I'm struggling with testing even after looking for examples and tutorials, my tests are not working but I'm not sure if the issue is Chai related or my API server.

All the code is open source and available here .

I have an endpoint who should return all exercises as a list: GET /v1/exercises

Here is my test:

 'use strict' const chai = require('chai') const chaiHttp = require('chai-http') chai.should() const app = require('../src/app') chai.use(chaiHttp) const expect = require('chai').expect describe('Exercise', () => { it('Should get all exercises', (done) => { chai.request(app).get('/v1/exercises').end((err, res) => { const result = res.statusCode expect(result).to.equal(200) done() }) }) })

And I get this error:

Error: Timeout of 2000ms exceeded. For async tests and hooks, ensure "done()" is called; if returning a Promise, ensure it resolves. (/Users/kevintassi/Documents/project/fitigai/api/test/01.exercise.spec.js)

You can see files here:

• Test file
• Route file
• Controller file

Do you know why this issue occurs? Note that I don't have this error is the endpoint is wrong, so the timeout is appear only when the function is processing I guess. But still don't get why.

I thank you a lot in advance for your time. Feel free to ask me more details if needed.

Answer 1

Issue wasn't related to Chai or Mocha.

It was the way how my app and server were config. Just moving the DB connection to app instead of server solve the issue since mocha make the listen to the app automatically, it know include the DB connection.

This was causing the timeout issue.
