Transform Your Code with Advanced PHP Testing Techniques

Why Learn to Test?

Learning to test isn't just a skill—it's a fundamental part of coding. When you understand testing, you understand how to write better, more robust code. Testing and coding go hand in hand, enhancing your development skills and boosting your confidence in the code you write.

Beyond the Basics

Sure, anyone can follow simple tutorials on how to assert that string 'foo' does not equal 'bar'. But what about the real challenges? How do you determine what to test, the order of tests, or where to even start? How do you ensure your code is adequately covered by tests? What about code that seems impossible to test? These aren’t just theoretical questions—they're real challenges that developers face every day.

What Sets This Course Apart?

While basic tutorials have their place, real-world applications demand deeper understanding and more sophisticated strategies. This course goes beyond simple examples to teach you how to design tests for complex, real-life PHP applications. You'll learn not just how to test, but how to think about testing in a way that makes your code bulletproof.

What You Will Learn in This Course

Mastering Your Testing Tools

🛠 Foundation in PHPUnit: Start by getting comfortable with PHPUnit, the cornerstone testing framework for PHP. You'll understand its essential role and how other frameworks like PEST and Codeception build upon its foundation. We begin with mastering this critical tool to set a solid groundwork for advanced testing.

Developing Testing Strategies

🎯 Practical Applications: Once you're set up with the necessary tools and have written your initial tests, we'll dive into more sophisticated testing strategies. Through a practical project that poses unique challenges, we'll employ a mix of unit tests, feature tests, and integration tests to enhance the code's robustness and coverage.

Expanding Your Testing Toolkit

🧰 Advanced Techniques: Explore an extensive section dedicated to test doubles, enhancing your ability to create focused and effective tests. This part of the course is designed to refine your skills and broaden your testing capabilities.

Applying Test Driven Development (TDD)

📚 In-Depth TDD Training: Engage with over 20 videos that take you through the practical application of TDD. You'll develop a complex functionality that involves handling different currencies and amounts— a challenging yet rewarding task. With TDD, we'll simplify complex scenarios and demonstrate how systematic testing can lead to cleaner, more reliable code.

Enhancing Code Quality with PHPStan

🔍 Static Analysis: Dive into static analysis with PHPStan, a leading tool that identifies issues in PHP code before it runs. Learn how to integrate PHPStan into your workflow to improve code quality and maintain standards effortlessly. This section focuses on preemptively catching bugs and ensuring your codebase remains robust and error-free.

Testing Class Methods

The courses starts by installing the PHPUnit testing framework and then writing our first tests. In this sample we look at testing class methods.

Errors vs Failures

Do you know the difference between test errors (E) and test failures (F)? You will by the end of this video.

Refactoring For Easier Testing

Sometimes your code might feel like it is hard to test. Instead of reaching for a bunch of workarounds involving test doubles etc. you should first ask yourself whether the code could be refactored to make it easier to test.

PHPUnit Test Doubles

Test doubles allow you to test the parts of your application that you want to test without having to rely on a bunch of dependencies being set up correctly...that could be complicated and painful.

Test Coverage

Test coverage is a measure of how much of the code base is executed when the tests are run. It is NOT an indicator that your code is fully tested because there could be many parts of your code which are executed when the tests run but which could have multiple outcomes...these are not factored into the test coverage score.

Flatten an Array

Our data comes back from an API as a multidimensional array but we want it in the shape which our application understands.

An underlying test will help us to flatten this array. We also want to preserve the keys for the individual values.

Full Request -> Response Test

Most PHP frameworks come with great testing tools. Let's run a full request -> response test using the Laravel framework.

Red > Green > Clean

This course includes an in-depth on Test Driven Development which adapts an example by Kent Beck. TDD is an interative process where you: 1. Quickly create a failing test. 2. Make that test pass by whatever means. 3. Refactor for clean code. I call these steps Red, Green, Clean

Time For A Reality Check

Many testing tutorials and courses rely on oversimplified examples like asserting that `1 + 1 = 2` to demonstrate basic concepts. While these examples are great for beginners to grasp the fundamentals, they fall short of preparing you for the complexities of real-world software development.

In this course, you won't find simplistic scenarios. Instead, I bring you into the trenches of actual development challenges.

As a senior developer actively working in the industry, I leverage my firsthand experience to provide you with examples and challenges I've encountered in my career. This approach isn't just about learning to test—it's about preparing to succeed in real environments where the quality of your testing can make or break a project.

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.
