how to test my project using selenium ?

• tell the integrator person to create a new runner machine which contains selenium
• the gitlab-ci web interface should list the new registered machines(the runners)
• the developer can assosiate a runner with his project by selecting a runner from a list.

can I change the runner-machine - and install another tool on it ?

• the build process is : pulling the repo code and then running the custom-script.
• update the custom-script to add more functionality.
