Maven project to start tests with Selenium Grid.

docker-selenium project on github

• Get Docker CE for Ubuntu
  • To run docker as a normal user, run this command : sudo usermod -a -G docker $USER and reboot your computer.
• Install Docker Compose
• To execute the docker-compose yml file use docker-compose -f composer/docker-compose.yaml up.
  • Add the -d flag at the end for detached execution.
  • To stop the grid and cleanup the created containers, run docker-compose -f composer/docker-compose.yaml down.
• Scaling up the grid on-demand : docker-compose -f composer/docker-compose.yaml up -d --scale firefox=2 --scale chrome=2.
• Remote address for the client : http://ipserver:4444/wd/hub (e.g.: http://localhost:4444/wd/hub)
• http://localhost:4444/grid/console
• Debugging : to debug your tests you have to use node-chrome-debug and node-firefox-debug (see the composer file). Go to http://localhost:4445/ to list the vnc access. The password is "sercret".
• You can share files between the host and the containers. It is usefull to upload files in a Web app. See /home/julien/test:/home/seluser/upload in the composer/docker-composer.yaml and adapt to your case. seluser is the user in the containers.
• You can rename the folder composer in seleniumv3 (for example) if you want to identify easily the containers in the list displayed by http://localhost:4445/
• If you want to set the timeouts, add GRID_TIMEOUT and GRID_BROWSER_TIMEOUT to the hub in the docker-compose.yaml. To learn more about the timeouts, see also the Grid2 wiki.

    hub:
        image: selenium/hub:3.141.59
        restart: on-failure
        ports:
            - "4444:4444"
        environment:
            - GRID_TIMEOUT=300
            - GRID_BROWSER_TIMEOUT=300

If you can't use docker, you can use this solution.

• Download selenium-server-standalone
• Download geckodriver
• Download chromedriver

hub :

java -jar selenium-server-standalone-3.141.59.jar -role hub

node :

java -jar selenium-server-standalone-3.141.59.jar -role node -hub http://localhost:4444/grid/register

mvn test
