Selenium-Grid + PHPUnit + Docker

Requirements

• Docker
• Composer
• VNC Viewer (optional)

Install

Use Composer and run

composer install

Running Standalone Server

Chrome

$ docker run -d -p 4444:4444 selenium/standalone-chrome

Firefox

$ docker run -d -p 4444:4444 selenium/standalone-firefox

NOTE (from Selenium Docker readme): When executing docker run for an image with Chrome or Firefox please either mount -v /dev/shm:/dev/shm or use the flag --shm-size=2g to use the host's shared memory.

Example

$ docker run -d -p 4444:4444 -v /dev/shm:/dev/shm selenium/standalone-chrome
# OR
$ docker run -d -p 4444:4444 --shm-size=2g selenium/standalone-chrome

Running a Grid

$ docker run -d -p 4444:4444 --name selenium-hub selenium/hub:3.4.0
$ docker run -d -P --link selenium-hub:hub selenium/node-chrome:3.4.0
$ docker run -d -P --link selenium-hub:hub selenium/node-firefox:3.4.0

Watching Tests

Use the IP/Port with the VNC Viewer. The passwort is secret:

$ vncviewer 0.0.0.0:49338

Note: use docker ps to see container port to access from VNC

Using PHPUnit

Every test is executed in order. This should take ~6s.

$ vendor/bin/phpunit --verbose --bootstrap vendor/autoload.php tests/ExampleGrid
