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

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'

I can bring up the following containers:

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
hub:
image: elgalu/selenium
ports:
- ${VNC_FROM_PORT-40650}-${VNC_TO_PORT-40700}:${VNC_FROM_PORT-40650}-${VNC_TO_PORT-40700}
is not needed at all.
Just point your tests to the zalenium service, since you are using docker-compose.
http://zalenium:4444/wd/hub
