How to use with puppeteer-core instead of puppeteer

[incoming-th]

What are you trying to achieve?

I try to install CodeceptJS with puppeteer-core as I want to use it with Browserless, therefore no need to install the default Chromium browser bundled with puppeteer

What do you get instead?

When running the tests, the puppeteer libray is indeed not found:

Provide console output if related. Use --verbose mode for more details.

Could not load helper Puppeteer from module './helper/Puppeteer':
Required modules are not installed.

RUN: [sudo] npm install -g puppeteer@^1.6.0

Details

• CodeceptJS version: ^2.3.6
• NodeJS Version: 10.15.2
• Operating System: Ubuntu 19.10
• puppeteer(-core): ^1.20.0
• Configuration file:

exports.config = {
  tests: './scripts/*_test.js',
  output: './logs',
  helpers: {
    Puppeteer: {
      url: 'http://localhost',
      show: false,
      restart: false,
      waitForNavigation: "networkidle0",
      chrome: {
        browserWSEndpoint: "wss://chrome.browserless.io/"
      },
    }
  },
  include: {
    I: './steps_file.js'
  },
  bootstrap: null,
  mocha: {},
  name: 'worker'
}

Note to self: instead of trying to "hack" the actual Puppeteer helper, I think it should be better to extend Puppeteer into a new PuppeteerCore.

The best way to avoid to download Chromium and not modifying the code is to run installation in this order:

npm config set puppeteer_skip_chromium_download true
npm install puppeteer

Based on this npm_config_puppeteer_skip_chromium_download the download will be skipped.

This will add the first line into your npm configuration file. You can check by typing:

npm config ls -l

This solution is better than asking support for puppeteer-core, therefore I will close the issue.

Thanks for sharing your work @MickaelTH , it helped me to figure out how to integrate https://github.com/alixaxel/chrome-aws-lambda with codecept!
