Build and Test Real Symfony Applications

Build Better, Test Smarter


With this bundle, you’ll go beyond just building applications. You’ll also learn how to write clean, maintainable Symfony code and back it up with a reliable test suite.
That way you can ship your projects with confidence, knowing everything works as expected.With Symfony Build & Test Essentials, you get both sides of the equation:

1️⃣ A complete microservice project that shows you how to structure routes, controllers, DTOs, validation, and persistence the right way.

2️⃣ A full testing workflow where you’ll learn to write application and unit tests that are fast, meaningful, and easy to maintain.

Instead of jumping between random docs or disconnected videos, you’ll follow a clear, step-by-step path. Each concept builds on the last, so you always know where you are and why it matters.
You’ll have access to X bite-sized video lessons, each paired with written explanations and real code examples. This means you can learn at your own pace—watch a demo, read through the details, copy and adapt the code. Every lesson is short, focused, and designed to move you forward without big leaps or hidden gaps.
By the end, you won’t just “know Symfony.” You’ll be able to build real applications, test them properly, and ship your work with confidence.

Everything You Get

Full access to both courses covering modern Symfony development and testing best practices.

Symfony 7 Microservice

🧵 Create a webhook-based Symfony microservice for real-time data sync. Learn how to build a responsive, event-driven microservice using Symfony 7. In this project-based course, you’ll create a webhook subscriber that transforms and forwards data to a Customer Data Platform (CDP). Perfect for developers working with async systems or real-time integrations. 👉 Learn microservices in practice — not just theory.

Testing Symfony

Learn to Test Symfony Applications with Confidence Testing Symfony is a hands-on course that teaches you how to write fast, reliable, and meaningful tests for real-world Symfony apps. You'll build a simple job application system and test every part of it - from form validation and file uploads to database persistence and external HTTP requests. Each lesson shows you how to write meaningful Symfony tests - from application and unit tests to file uploads, email, database isolation, and HTTP client testing. You'll learn practical techniques using Symfony's built-in tools, along with PHPUnit, DAMA\DoctrineTestBundle, and Symfony’s MockHttpClient. Whether you're new to testing or want to improve your Symfony test suite, this course will give you the skills and confidence to write tests that actually matter.

Symfony Application Tests

In Symfony, an application test (sometimes called a feature test) interacts with your app in the same way a real user or browser would:
It makes an HTTP request, gets a response, and inspects that response for the expected content.

Test Fixture Files

When writing application tests, it’s important to make them as realistic as possible. If your app allows users to upload files, your tests should also cover that flow. Otherwise, you risk shipping code that works fine with plain form fields but breaks the moment a real file upload is involved.

Application Architecture

Let's have a look at the application architecture and the steps we shall take to arrive at a point where we can dispatch the correct data.

Validator Component

The Symfony validator component, like all Symfony components, can be used in Symfony Framework projects or, of course, any non-Symfony project.

Frequently Asked Questions (FAQs)

(Please email me at [email protected] with any questions. We reply within 48 hours)

Q. What is the Symfony Build & Test Bundle?
A. It’s a two-course bundle that gives you the best of both worlds:
✅ Testing Symfony – Learn how to test real Symfony applications using application tests, unit tests, doubles, and more.
✅ Symfony Microservice – Build a real-world webhook microservice using Symfony 7, and learn modern, event-driven techniques used in production.


Q. Do I need to be an expert in Symfony?
A. Not at all. You just need a basic understanding of how a Symfony app is structured. Both courses explain every concept clearly and guide you through the code one step at a time.


Q. What kinds of skills will I learn?
A. You’ll build a real Symfony microservice and learn advanced architecture patterns, then test it all with confidence using PHPUnit and Symfony’s built-in testing tools. You’ll cover webhooks, DTOs, email and file upload testing, custom service injection, and much more.


Q. Is this bundle beginner-friendly?
A. If you’re completely new to testing, I recommend starting with Testing PHP, which covers foundational concepts first. But if you’ve built basic Symfony apps before and want to level up fast, this bundle is perfect.


Q. Are the courses all video-based?
A. Yes - over 85 practical video lessons across both courses. Every lesson is straight to the point, full of real-world techniques, and designed to help you apply what you learn immediately.


Q. Will I have lifetime access?
A. Yes. One-time payment, lifetime ownership - including all future updates. No subscriptions, no upsells, no surprises.


Q. Who is this bundle for?
A. Symfony developers who want to:
1️⃣ Build real-world apps using scalable patterns
2️⃣ Write confident tests for everything they build
3️⃣ Deepen their understanding of modern PHP development

Here is what people have said about my previous Testing PHP course


This was an amazing course, and I've learned a lot of new things that I didn't knew even existed! This has provided me with solid know-how on the testing php subject, which tends to be overlooked by so many programmers. Horatiu

Gary Clarke’s teaching way is crystal clear and complete.- Lorenzo Sequi


I need to learn to use PHPUnit in both a more legacy context (where upgrading to v10+ isn't an option yet) and I also want to learn to test in an up to date way. The source is handling this very nicely. I really appreciate the attention to detail on supporting both Symfony versions as well. Lau Bannenberg

Who Am I?


Hello and thank you so much for checking out my work. My name is Gary Clarke and I'm a software developer with many years experience, primarily in PHP. I started creating video tutorials during lockdown in 2020 because I wanted the challenge of being able to explain complex / technical subjects to others in a way which is easy to understand and remember.


At this moment in time, my videos have been watched over a million times and I intend to keep creating new and improved content and teaching more and more new people. It would be my pleasure to see you on the inside of one of my courses.
