Using Pa11y with Supertest

Question

What is the best way to use Pa11y with Supertest? Something like:

describe ('my page', function () {
    it ('is accessible', function () {
        request (server).get ('/').expect (function ({ body }) {

            // How to run Pa11y here?

        });
    });
})

pa11y is for testing accessibility and supertest for HTTP node servers. I'm not sure why you would want to test those 2 things together. — Matthew Blewitt, Jul 11 '18 at 12:20
Sorry what I meant is that you might not need super test at all for this as pa11y can ping url's. — Matthew Blewitt, Jul 12 '18 at 10:41
Thanks, I did end up going with a separate test script using pa11y-ci when I struggled with this method. — Danyal Aytekin, Jul 12 '18 at 16:20
Yeh, I've found it to be a more flexible package, plus you get all the informative CLI errors. Good reference here https://bitsofco.de/pa11y/#doingmorewithpa11y — Matthew Blewitt, Jul 13 '18 at 10:13
Just out of interest how did you setup pa11y-ci to run with a local server? — Matthew Blewitt, Jul 13 '18 at 14:17

I would suggest not using supertest at all for these accessibility test as pa11y can ping url's directly.

const pa11y = require('pa11y');
const request = require('supertest');
const mocha = require('mocha');
const { expect } = require('chai');
const server = require('./server');

const url =
  process.env.NODE_ENV === 'testing'
    ? 'http://localhost:3000'
    : 'http://example.com';

describe('my page', function() {
  it('is accessible', function(done) {
    pa11y(`${url}/`, function(err, results) {
      expect(results.issues).to.be.empty;
      done();
    });
  });
});

This is nice. Thanks! – Danyal Aytekin Jul 12 '18 at 16:21 — Danyal Aytekin, Jul 12 '18 at 16:21
