Usage

To use this image to run your app tests you can add the following to a docker-compose.yml file:

version: '2'
services:
    webdriverio:
        image: huli/webdriverio:latest
        depends_on:
            - chrome
            - firefox
            - hub
        environment:
            - HUB_PORT_4444_TCP_ADDR=hub
            - HUB_PORT_4444_TCP_PORT=4444
        volumes:
            - {{replace_with_path_of_wdio.conf.js_file}}:/app

    hub:
        image: selenium/hub
        ports:
            - 4444:4444

    firefox:
        image: selenium/node-firefox
        ports:
            - 5900
        environment:
            - HUB_PORT_4444_TCP_ADDR=hub
            - HUB_PORT_4444_TCP_PORT=4444
        depends_on:
            - hub

    chrome:
        image: selenium/node-chrome
        ports:
            - 5900
        environment:
            - HUB_PORT_4444_TCP_ADDR=hub
            - HUB_PORT_4444_TCP_PORT=4444
        depends_on:
            - hub

Then simply run:

docker-compose run --rm webdriverio wdio

Configuration

This image comes with the following packages preinstalled:

Troubleshooting

ERROR: Error forwarding the new session Empty pool of VM for setup Capabilities

Sometimes the browsers might not have enough time to connect to the hub. You can either:

Make it in two steps: first run docker-compose up -d chrome firefox hub then docker-compose run --rm webdriverio wdio
Or you can add a sleep time to make sure the hub is ready: docker-compose run --rm webdriverio bash -c "sleep 10 && wdio".
