Here we have a simple sample, to run puppeteer and check OK or NOT browsing uno site.
educacion@family:~/src$ hg clone https://bitbucket.org/maximilianou/docker17_puppeteer
educacion@family:~/src/docker17_puppeteer/frontest$ docker-compose up

const assert = require('assert');
const puppeteer = require('puppeteer');
describe("Browsing with puppeteer:", ()=> {
describe("Geting one page", ()=>{
it("Check OK:", async ()=> {
const browser = await puppeteer.launch({
args: [
'--no-sandbox',
'--disable-setuid-sandbox'
]
});
const page = await browser.newPage();
await page.goto('https://bitbucket.org/maximilianou/'); //, {waitUntil: 'networkidle2'});
let textResponse = await page.evaluate(() => {
//Maximiliano Usich
let elemCheck = document.querySelector('a[href="/maximilianou/"]');
return elemCheck.innerHTML;
});
assert( textResponse === 'Maximiliano Usich', "[OK] Content Found" );
browser.close();
});
it("Check Not Found:", async ()=> {
const browser = await puppeteer.launch({
args: [
'--no-sandbox',
'--disable-setuid-sandbox'
]
});
const page = await browser.newPage();
await page.goto('https://bitbucket.org/maximilianou/UPS!!');// , {waitUntil: 'networkidle2'});
let textResponse = await page.evaluate(() => {
//Maximiliano Usich
let elemCheck = document.querySelector('a[href="/maximilianou/"]');
return elemCheck;
});
assert( textResponse === null, "[OK] Content Not Found" );
browser.close();
});
});
});

ERROR: when an error like this happen
docker-test-puppeteer | 1) Browsing with puppeteer:
docker-test-puppeteer | Geting one page
docker-test-puppeteer | Check OK::
docker-test-puppeteer | Error: Timeout of 10000ms exceeded. For async tests and hooks, ensure "done()" is called; if returning a Promise, ensure it resolves. (/app/test/index.spec.js)
The site did NOT responde on time ( 10000 milis).
We have configured this in package.json

This is the way of code, set the timeout in the it().timeout(0), because mocha take 2 seconds.
