Running dockerized Behat BDD Tests using Zalenium ( scalable selenium grid )

Question

I am trying to Run Behat BDD Tests using docksal/behat docker-compose ( ref: https://github.com/docksal/behat)

Looking at the Zalenium documentation

Pull docker-selenium

    docker pull elgalu/selenium

# Pull Zalenium

docker pull dosel/zalenium

# Run it!

docker run --rm -ti --name zalenium -p 4444:4444 \

  -v /var/run/docker.sock:/var/run/docker.sock \

  -v /tmp/videos:/home/seluser/videos \

  --privileged dosel/zalenium start

# Point your tests to http://localhost:4444/wd/hub and run them

integrating docksal/behat and zelenium is not clear

using. the. following docker-compose.yml

# The purpose of this -test example is for the e2e tests of this project

#

# Usage:

#  docker-compose -p grid up --force-recreate

#  docker-compose -p grid scale mock=1 hub=1 chrome=3 firefox=3

version: '2.1'

services:

  hub:

    image: elgalu/selenium

    ports:

      - ${VNC_FROM_PORT-40650}-${VNC_TO_PORT-40700}:${VNC_FROM_PORT-40650}-${VNC_TO_PORT-40700}

  zalenium:

    # Run a built-in web server for access to HTML reports

I can bring up the following containers:

CONTAINER ID        IMAGE                    COMMAND                  CREATED             STATUS              PORTS                                  NAMES

now looking at run-behat in examples directory:

basically executing

$docker exec $(docker-compose ps -q behat) behat --colors --format=pretty --out=std --format=html --out=html_report "$@"

I get an error:

Error response from daemon: Container 411c6b89d8f382a64ed567dbe4d02a2840f06d4778f1ce7bcf955e720d96ab02 is not running

whereas:

$ docker-compose ps -q behat

411c6b89d8f382a64ed567dbe4d02a2840f06d4778f1ce7bcf955e720d96ab02

Perhaps in behat.yml wd_host: http://localhost:4444/wd/hub

it should not point to localhost, but rather the hub? since wd_host should point to the selenium grid running in the container?

Answer 1

This part of your code is not needed at all:

hub: image: elgalu/selenium ports: - ${VNC_FROM_PORT-40650}-${VNC_TO_PORT-40700}:${VNC_FROM_PORT-40650}-${VNC_TO_PORT-40700}

Just point your tests to the zalenium service, since you are using docker-compose like this:

http://zalenium:4444/wd/hub

This should help you!
