​Description

This is a 1-day hands-on workshop that focuses on understanding how Selenium Grid 4 works and how to run your grid effectively, using best practices culled from several large grid installations. Particularly participants are expected to learn:

• 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

Who should attend

This workshop can be attended by anyone who wants to learn about setting up, debugging, scaling and driving observability and with Selenium Grid 4.

What will you learn

During this 1-day hands-on workshop participants will have the opportunity to learn:

Introduction

• 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?

Set-up

• 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 set up a standalone & grid:hub-node using docker?
• Using docker-compose to simplify docker grid setup process

Running

• 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

Extras:

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

​Prerequisites

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

Participants are requested to bring their own laptop.
Moreover you will find all the necessary software requirements detailed in this document.
