Some example Mocha, Supertest, and Superagent tests I've written

SomeSpecUsingSuperagent.js

/*
  Note: 
  Uses superagent and mocha assertions.  
  This is how I do these tests nowdays, without supertest, just plain superagent.
*/

import request from 'superagent'

  it('returns a list of participants', async () => {
      const url = 'https://someurl';
      const response = await request
        .get(url)
        .set({ Authorization: `Bearer xxxxxxxxxx` })
        .accept('application/json')

    const participants = response.body.data

    expect(participants.length).to.equal(2)
  })

SomeSpecUsingSupertest.js

/*
    Note:
    I'm not really using supertest's assertion lib in this example; it's just using supertest as a way to get to superagent 
    (which in this case is totally unecessary) and then instead of supertest's assertion lib, simply using mocha asserts :).
    
    Furthermore, the style here is I like to seperate out my arrange, act, assert into variables that read well, 
    then makes my ultimate assertion simpler and so overall easier to read and debug if I need to debug
*/

import supertest from 'supertest';
import app from '../../app';

describe.skip('Company - Integration Tests', () => {
    let request;

    before(() => {
        const service = app.listen(4000);
        request = supertest.agent(service);
    });

    it('returns a featured company', async () => {
        const uri = '/companies/featured',
            response = await request.get(uri);

        expect(response.body.id).to.equal("1");
    });
});
