Nothing is more reassuring when working on a codebase than knowing that if you accidentally break something, a test will alert you.

But it’s not all about your code.

Can you be sure that none of the plugins that you use break your code on an update?

Are you confident that you can update PHP versions without causing issues?

Do you feel comfortable rewriting old code, or do you avoid touching anything that “works”?

Whether you build websites for clients, or sell plugins–you don’t want to break people’s websites.

And automated tests are the number one tool to catch bugs before they hit production.

WP PHP Unit Testing Explained is a comprehensive video course that teaches you how write these tests.

What you’ll learn

At the end of this course, you’ll be able to write unit tests for plugins or entire projects.

You’ll also understand how these tests are integrated into the development process to flag issues before code is deployed to production.

To achieve this, we’ll focus on these six areas:

1. Understanding automated testing in WordPress: Whether you have testing experience or not. You’ll understand the big picture behind how WordPress approaches testing.
2. Test suite setup: To write and run tests, you need to set them up on your local environment. You’ll discover what tools there are, and how to use them.
3. Testing Fundamentals: Discover the foundations of testing: writing the tests, running them, and interpreting the results.
4. Handling test data: Learn how you can prepare the test environment with the content and data you need to efficiently test your code.
5. Testing strategies: What are the strategies to use tests in the most efficient way?
6. Project setup: The testing setup depends on whether you want to test an entire project, or just a plugin. It’s also different if you start fresh compared to adding to an existing codebase. This section will walk through the best approach for each of these cases.

Be part of the pre-relaunch

You might be thinking: What?

Let me explain.

I created a first version of a WordPress PHP unit testing course in 2016, and updated it regularly until 2022.

While this course is still up to date, the other courses I created gave me more experience in curriculum design, and lesson structure.

So I want to start from scratch, and make a course that’s more complete, and as useful as possible.

And for that I need your help.

As part of the prelaunch group, I’m looking for your feedback on what to add to the course. I also want to hear any comments you have about the lessons. I’ll redo them as often as I have to to make them the best possible version.

To achieve this, the lessons will be published in batches, with the first batch scheduled for 28 October 2024.

And to thank you for your help, I’ll give you a free code review. We’ll get on a call, and you’ll get direct feedback from me on the unit tests you’ve written on your projects.
