I am trying to setup browser testing with selenium and docker with behat.
The main issue I am having is reliability when running the tests.
Sometimes I can get connected and am able to run tests fine, but a lot of the time I cannot.
It seems quite inconsistent, I startup the containers and run tests, first time fails, run again, the second time it runs and works fine.
Once I restart the selenium-hub and run tests again it's fine (mostly).
Thanks for the help.
A common error I get is:
Could not open connection: session not created exception
from disconnected: unable to connect to renderer
