Selenium Grid can be a bit daunting to get up and running. Starting it is quite easy, but using it effectively can require pulling in third-party tools. In this workshop we’ll cover how to run your grid effectively, using best practices culled from several large grid installations.


Outline/Structure of the Workshop

  • Describe what the grid is intended to solve, then get into how it solves it
  • Going deeper into the funnel, how does it get its instructions, and how does it pass them to the nodes?


  • We’ll start with the conventional setup of hub and node servers running on the same box, for simplicity.
  • Different options and flags that can be used when starting the hub/node processes
  • What kinds of logging do the nodes/hubs do that can help in debugging and investigating problems?
  • What is Docker?
  • How do you setup standalone & grid:hub-node using docker?
  • Using docker-compose to simplify docker grid setup process


  • How do you run a test in a container?
  • How do you run a test against the docker grid setup?
  • How do you look at the logs of tests running in a container?

Advanced Grid:

  • How to build your own docker image with custom browser versions
  • Creating a hybrid Selenium Grid (docker + a local IE/Safari node).
  • Integrating Selenium Grid to the CI pipeline (Jenkins).
  • Setting up a UI manager for all your docker installations
  • How do you scale containers?
  • Running tests in parallel against a scaled Selenium Grid


  • Selenium Grid on Amazon ECS using ecs-selenium
  • Overview of third-party tools

Learning Outcome

  • What Selenium Grid is and are its capabilities
  • How to run a grid
  • How to scale nodes
  • How to debug
  • How to build your own docker images for custom browser requirements

Target Audience

Anyone who wants to learn about setting up, debugging, scaling and driving observability and with Selenium Grid 4

Prerequisites for Attendees

Knowledge of Selenium is a mandatory requirement, as the workshop will only focus on the Selenim Grid and won't cover how to write a script.

Docker Environment

Windows: https://docs.docker.com/engine/installation/windows/

  • This will include installing Hyper-V

Mac: https://docs.docker.com/engine/installation/mac/

  • This will include installing the latest version of VirtualBox

Linux Distributions: https://docker.github.io/engine/installation/linux/

  • The requirements will vary depending on the flavor of Linux being used

Selenium-server-jar (latest): https://bit.ly/327RZjR

Latest Selenium 4 version: 4.3.0.jar

You will also need the browser drivers and language bindings necessary for your target configuration, listed on this page: https://www.selenium.dev/downloads/


  • If you intend to work with an auto-scaling Grid, an AWS account with full EC2 permissions.
  • It is also recommended that you have Eclipse or IntelliJ, a GitHub account, and an open USB port so participants can share files using a thumb drive.
Tracing Selenium Grid
  1. Install Coursier via a homebrew `brew install coursier/formulas/coursier`
  2. Install Jaeger via docker
