June 10, 2025 — Every day countless WordPress sites are compromised or hacked. This simple fact has led site owners around the world to ask one question: why is WordPress so insecure?

This session will teach you how to think with a security first mindset, how to write secure code, and how to protect your site against the number one threat: humans.

June 10, 2025 — Like many self-taught developers, I started out on my own, relying on the examples at hand and Google searches. 12 years later, 8 of which I have been working with WordPress, I want to talk about “How to Grow as a WordPress Developer” to help others avoid the mistakes I made and speed up the process. I believe that contribution is a key component of this growth, and I will show how and why it can be beneficial, as well as discuss other ways to get knowledge and experience needed. I also believe that learning should start with the system architecture and APIs, going deeper when necessary, and I will present my list of things on which WordPress developers can build their own understanding of the system.

June 7, 2025 — The goal of this workshop is to show how easy it is to start testing WordPress projects and enable participants to implement tests in their own projects.
In the workshop we will write integration and end-to-end tests for a typical WordPress plugin.

We will run tests using WordPress Playground, so they can run inside the WordPress context, each test can run on a differently configured site, and we can test the project using both PHP and HTTP requests.

To start we will fork a plugin from GitHub and learn how to run it locally using the Playground CLI. After that, we will implement integration and end-to-end tests for our plugin using Playground.

Once we have all tests working we will add a GitHub action to run these tests on every commit in GitHub.
