Puppeteer

# Puppeteer

Extends Helper

Uses Google Chrome's Puppeteer (opens new window) library to run tests inside headless Chrome. Browser control is executed via DevTools Protocol (instead of Selenium). This helper works with a browser out of the box with no additional tools required to install.

Requires puppeteer package to be installed.

Experimental Firefox support can be activated (opens new window).

# Configuration

This helper should be configured in codecept.json or codecept.conf.js

  • url: base url of website to be tested
  • basicAuth: (optional) the basic authentication to pass to base url. Example: {username: 'username', password: 'password'}
  • show: - show Google Chrome window for debug.
  • restart: - restart browser between tests.
  • disableScreenshots: - don't save screenshot on failure.
  • fullPageScreenshots - make full page screenshots on failure.
  • uniqueScreenshotNames: - option to prevent screenshot override if you have scenarios with the same name in different suites.
  • keepBrowserState: - keep browser state between tests when restart is set to false.
  • keepCookies: - keep cookies between tests when restart is set to false.
  • waitForAction: (optional) how long to wait after click, doubleClick or PressKey actions in ms. Default: 100.
  • waitForNavigation: . When to consider navigation succeeded. Possible options: load, domcontentloaded, networkidle0, networkidle2. See Puppeteer API (opens new window). Array values are accepted as well.
  • pressKeyDelay: . Delay between key presses in ms. Used when calling Puppeteers page.type(...) in fillField/appendField
  • getPageTimeout config option to set maximum navigation time in milliseconds. If the timeout is set to 0, then timeout will be disabled.
  • waitForTimeout: (optional) default wait* timeout in ms. Default: 1000.
  • windowSize: (optional) default window size. Set a dimension like 640x480.
  • userAgent: (optional) user-agent string.
  • manualStart: - do not start browser before a test, start it manually inside a helper with this.helpers["Puppeteer"]._startBrowser().
  • browser: - can be changed to firefox when using puppeteer-firefox (opens new window).
  • chrome: (optional) pass additional Puppeteer run options (opens new window).

# Example #1: Wait for 0 network connections.

{
   helpers: {
     Puppeteer : {
       url: "http://localhost",
       restart: false,
       waitForNavigation: "networkidle0",
       waitForAction: 500
     }
   }
}

# Example #2: Wait for DOMContentLoaded event and 0 network connections

{
   helpers: {
     Puppeteer : {
       url: "http://localhost",
       restart: false,
       waitForNavigation: [ "domcontentloaded", "networkidle0" ],
       waitForAction: 500
     }
   }
}

# Example #3: Debug in window mode

{
   helpers: {
     Puppeteer : {
       url: "http://localhost",
       show: true
     }
   }
}

# Example #4: Connect to remote browser by specifying websocket endpoint (opens new window)

{
   helpers: {
     Puppeteer: {
       url: "http://localhost",
       chrome: {
         browserWSEndpoint: "ws://localhost:9222/devtools/browser/c5aa6160-b5bc-4d53-bb49-6ecb36cd2e0a"
       }
     }
   }
}

# Example #5: Target URL with provided basic authentication

{
   helpers: {
     Puppeteer : {
       url: 'http://localhost',

       show: true
     }
   }
}

Note: When connecting to remote browser show and specific chrome options (e.g. headless or devtools) are ignored.
