Using Pa11y with Supertest - accessibility

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?
});
});
})

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();
});
});
});

Axios onUploadProgress not called on Nuxtjs project when nuxt#pwa and nuxt#firebase modules installed

A noticed that onUploadProgress from axios are not being called at all on my Nuxt.js Project. After some debugging I found out it is related to the "#nuxtjs/pwa" and "#nuxtjs/firebase" modules. I use firebase auth, and the PWA module uses a service worker to take care of SSR auth and inject the auth token on outgoing requests.
This modules are interfering somehow on the axios onUploadProgress. I use axios to upload files to other Apis.
Once I remove the "#nuxtjs/pwa" module the onUploadProgress from axios gets called normally.
Does anyone have an idea how to fix that?
The versions of the modules:
"#nuxtjs/axios": "^5.13.6",
"#nuxtjs/firebase": "^7.6.1",
"#nuxtjs/pwa": "^3.3.5",

NextJS Build error: package.json does not exist at /package.json

I have been working on a NextJS application that utilizes Firebase. I have everything set up and on build I get the following error: package.json does not exist at /package.json (see the image)
build error
To give more context on this:
NextJS v^9.3.0
Firebase v^7.10.0
Target: server (by default)
My next.config.js:
const path = require('path')
const resolve = require('resolve')
const withCSS = require('#zeit/next-css')
const withImages = require('next-images')
const withFonts = require('next-fonts')
const withTM = require('next-transpile-modules')([
'*************',
'*************',
'*************'
]);
if (typeof require !== "undefined") {
require.extensions[".less"] = () => {};
require.extensions[".css"] = (file) => {};
}
module.exports =
withCSS(
withImages(
withFonts(
withTM({
webpack: (config, options) => {
config.module.rules.push({
test: /\.svg$/,
use: ['#svgr/webpack'],
});
const { dir, isServer } = options
config.externals = []
if (isServer) {
config.externals.push((context, request, callback) => {
resolve(request, { basedir: dir, preserveSymlinks: true }, (err, res) => {
if (err) {
return callback()
}
if (
res.match(/node_modules[/\\].*\.css/)
&& !res.match(/node_modules[/\\]webpack/)
&& !res.match(/node_modules[/\\]#aws-amplify/)
) {
return callback(null, `commonjs ${request}`)
}
callback()
})
})
}
return config;
},
cssLoaderOptions: {
url: false
}
})
)
)
)
I have been trying many solutions, including the following:
- I should use target server, but I have also tried with "experimental-serverless-trace" but no effect, same error persists
- Tried also "webpack-asset-relocator-loader" but it doesn't work as well. When utilized, I get the following error: "gRPC binary module was not installed".
To be honest, at this point I do not have any idea where to go from this point.
Thanks!

How to test router code that contains heavy logic using sinon and stubbing (nodeJS)

I am new to using sinon, so sorry if my question is weird, I looked everywhere but can't find a way to do it.
I have app with express router. I want to write uint test for one of the routes. That route have an inner function that is 'heavy', meaning that it is async with promise, and in reality calls an external api. I want to stub that inner function in the test so that it will not use the api, and will return my own data instead of the original method.
This is the code so far:
routes/setOrder.js:
// the inner function I want to stub
var verifyPayment = function(saleId) {
return new Promise((resolve, reject) => {
logger.info(`verifyPayment: ${saleId}`);
externalAPICall.get( // <==this is the 'heavey part!!
saleId,
function (error, sale) {
if(error) {
return reject(`Error querying sale(${saleId}): ${error}`);
}
resolve(sale);
});
});
}
router.get('/paymentId/:paymentId', setOrderWithGet);
const setOrderWithGet =async function(req, res, next) {
const { paymentId } = req.params;
verifyPayment(paymentId)
.then(async sale => {
try {
console.log(`sale:${sale}`);
res.send(JSON.stringify({"status": "ok!" }));
} catch (err) {
logger.warn(err)
res.send(JSON.stringify({"status": "fail.."}));
}
})
.catch(reason => {
logger.warn(`[] Payment(${paymentId}) is not valid ${reason}`);
res.send(JSON.stringify({"status": "fail.."}));
});
}
module.exports = router;
module.exports.setOrderWithGet = setOrderWithGet;
module.exports.verifyPayment = verifyPayment;
setOrderTest.js:
const setOrderStub = require('../routes/setOrder');
describe("POST /setOrder", () => {
beforeEach(() => {
sinon.stub(setOrderStub, 'verifyPayment').resolves({....});
});
afterEach(() => {
sinon.restore();
});
describe("test1", () => {
it("setOrder first attempt", () => {
let req ={params : {'paymentId' : 'mypamentid1'}};
setOrderStub.setOrderWithGet(req,{});
});
});
});
This line:
sinon.stub(setOrderStub, 'verifyPayment').resolves({....});
...stubs the verifyPayment function on the module exports of the setOrder module.
Right now setOrderWithGet is calling the verifyPayment function directly, so it is unaffected by any changes to the module exports.
Change setOrderWithGet to call verifyPayment using the module exports:
const setOrderWithGet = async function(req, res, next) {
// ...
module.exports.verifyPayment(paymentId) // <= call the module export for verifyPayment
// ...
}
...and your stub will get called.

Problem with CORS. Google directions API GET request | vue.js

I currently work on vue.js project.
The app goal is to check distance between 2 localisations, then show route on the map and calculate cost of transport which is based on the distance.
I use google directions api, axios for get request.
Problem is that, because of CORS, get request gives me an error (I run this app locally).
I already tried chrome CORS plugin, but problem still exists.
Do You have any solutions or just idea how to solve this problem?
Thank You in advance.
P.S.
Code below
import axios from 'axios';
const directionsApi = 'https://maps.googleapis.com/maps/api/directions/json?';
const apiKey = '&key=trust_me_the_key_is_valid';
export default {
name: 'FirstForm',
data() {
return {
fromValue: '',
toValue: '',
distance: '',
};
},
methods: {
handleFromToInput: function () {
const fromTo = `origin=${this.fromValue}&destination=${this.toValue}`;
axios.get(`${directionsApi}${fromTo}${apiKey}`)
.then((response) => {
// this.distance = response.routes[0].legs[0].distance.text;
console.log(response.routes[0].legs[0].distance.text);
})
.catch((error) => {
console.log(error);
});
},
},
};

Spy dataLayer from Google Analytics with Puppeteer and Mocha / Sinon (or similar)

So, I am trying to make automatic tests on my Google Analytics calls with Headless Chromes + Puppeteer + Mocha + Sinon but can't manage to read the dataLayer value for Sinon to spy.
This is what I have so far. But window is always undefined.
test is a class to proxy pass puppeteer calls to the inner browser.
const { test } = require('../browser');
const sinon = require('sinon');
const dataLayerName = 'dataLayer';
const assert = sinon.assert;
describe('Tests Analytics', () => {
let spy;
it('find home analytics', test(async (browser, opts) => {
const page = await browser.newPage();
await page.goto(`${opts.appUrl}`);
spy = sinon.spy(window.dataLayer, 'push');
assert.called(spy);
assert.calledWith(spy, [
'fail for me',
]);
spy.restore();
}));
});
This is the Browser class:
const puppeteer = require('puppeteer');
/**
* This is a thin wrapper so that we use a singleton of
* the browser that puppeteer creates
*/
class Browser {
setUp(done) {
const puppeteerOpts = this.options && this.options.puppeteer ?
this.options.puppeteer :
{};
puppeteer.launch(puppeteerOpts).then(async (b) => {
this.setBrowser(b);
done();
});
}
setBrowser(b) {
this.browser = b;
const oldNewPage = this.browser.newPage.bind(this.browser);
this.browser.newPage = async function () {
const page = await oldNewPage();
this.lastPage = page;
return page;
};
}
setOptions(opts) {
this.options = opts;
}
test(promise) {
return (done) => {
promise(this.browser, this.options)
.then(() => done()).catch(done);
};
}
}
/*
* Create a new browser and use a proxy to pass
* any puppeteer calls to the inner browser
*/
module.exports = new Proxy(new Browser(), {
get(target, name) {
return name in target ? target[name].bind(target) : target.browser[name];
},
});
This worked out for me:
let datalayer = await page.evaluate('dataLayer');
console.log(datalayer);
