README

Please continue to use dmore/behat-chrome-extension via Packagist

See https://gitlab.com/behat-chrome/chrome-mink-driver/-/issues/121 for details.

In short: I created placeholder Packagist packages in the behat-chrome/* namespace as part of that issue. DMore and I then decided to retain the original Packagist name , but a few folks appear to have picked up on the new Packagist name.

The Gitlab projects only are moved to https://gitlab.com/behat-chrome/

To undo the composer change:

composer remove behat-chrome/behat-chrome-extension behat-chrome/chrome-mink-driver
composer require dmore/behat-chrome-extension dmore/chrome-mink-driver

The behat-chrome/ packages on Packagist are now marked abandoned and point people back to dmore/

README continues

Behat extension for controlling chrome without the overhead of selenium.

It communicates directly with chrome over HTTP and WebSockets, which allows it to work at least twice as fast as chrome with selenium.

For chrome 59+ it supports headless mode, eliminating the need to install a display server, and the overhead that comes with it.

This driver is tested and benchmarked against a behat suite of 1800 scenarios and 19000 steps. It can successfully run it in less than 18 minutes with chrome 60 headless.

The same suite running against chrome 58 with xvfb and selenium takes ~60 minutes.

Installation:

composer require dmore/behat-chrome-extension

Requirements:

• Google chrome or chromium running with remote debugging

Example:

google-chrome-stable --remote-debugging-address=0.0.0.0 --remote-debugging-port=9222

or headless (59+):

google-chrome-unstable --disable-gpu --headless --remote-debugging-address=0.0.0.0 --remote-debugging-port=9222

The official docker image includes chrome 60 running headless.

See https://gitlab.com/DMore/behat-chrome-skeleton for a fully working example.
