Learning To Test IS Learning To Code

Learning how to test code is learning how to write code that is testable...the two go hand in hand. Once you perfect this skill, your dev abilities increase significantly along with confidence in your code.

There's a lot of material out there that shows you HOW to write basic tests that cover basic scenarios. Assert that string 'foo' does not equal 'bar'? No problem! But how do you know WHAT to test, in what order, and WHERE to start? How do you know that your code has sufficient test coverage? Is some code impossible to test? What would YOU do if it was?

SIMPLE EXAMPLES ARE FINE FOR LEARNING THE BASICS OF TESTING BUT THEY ARE NOT GOING TO TEACH YOU HOW TO TEST REAL APPLICATIONS...

I'm sorry but there's a lot more to it...The good news is that THE ANSWERS ARE ALL CONTAINED WITHIN THIS COURSE.

HOW DOES THAT SOUND SO FAR?..

..HERE'S WHAT'S COVERED IN THIS COURSE

The first thing that you need to do is to get comfortable with your testing tool(s). PHPUnit has been the de facto testing framework for PHP for many years. You will have heard of other testing frameworks such as PEST (check out my Test Driven PHP course) and Codeception..BUT..an important thing to know is that these frameworks are built on PHPUnit and cannot exist without it....so the first thing we'll do is master this important tool.

Once we are comfortable with our tools and our setup and we have written our first tests, it's then time to get serious and start to examine some testing strategies. For this we'll work on a small project which presents some challenges to testing. We will attack this code with a combination of unit tests, feature tests, and integration tests to leave the code in better shape and with maximum coverage.

We'll then have a look at a load of other things which you can introduce to your testing toolkit. There is an entire section dedicated to test doubles which will really help you make your testing more accomplished and focussed.

The section on Test Driven Development contains over 20 videos and shows you how to apply the 'theory' of TDD in practice. We'll create a piece of functionality which enables you to perform math with different amounts of money, in different currencies. Not an easy thing to do, with lots to think about..BUT with TDD we'll make it look easy!

Below is a list of the content that I cover. These are all of the core testing concepts that YOU NEED TO KNOW.

Best tutorial on this topic. Ilian Karasimirov

This course is very practical - Vakhtang

Very, very interesting and helpful - Ruslan

Course is clear, direct and easy to follow, even if one didn't use testing in the past - Richard

This is very useful course - Muhammad Nadeem

I didn't ever use phpunit because it was so hard to understand and figure out. This sets it up to be a success from the start to do TDD - Mr J

This course is very helpful in my php career - Asadullah

In depth course with great real life examples. Delivery of content is engaging and enjoyable - Joshua Caine

Really excellent course! - Brandon Oakley

Detailed in-depth premium content. Worth every penny - Janroe

Unit testing has been a low point in my professional PHP career the last few years. Have not found decent training anywhere. So glad to have found this course. - Karl Zipser

The course delivers a lot of specific knowledge that is not found anywhere else and the focus on complicated tests is very nice. The fact that the course keeps getting updated is a bonus. Eduardo

This course has clear explanations and Gary has the patience to explain every detail, which I think is very important. Demian

I like all your videos, great work. Keep rocking! Thank you for everything. Gokul jadhav.g

You explain the Mock in unittest with very easy understanding, you have reproduced different use cases that are very important to understand!! Thank you so much! 優散的傻勢

I have ADHD and have trouble with getting comfortable with tutorial styles and formats. Your video here is just bliss to me. Thank you thank you! Please don't stop making videos! Sofascialistadankula Megadonakeratosis

Clear and detailed. - Piero Recchia

The testing PHP course is long, but very good and amazingly informative. Testing is something that has always eluded me, so the course has definitely given me a grounding and something I can/will refer back to. Thanks for the course Gary and your other OOP course, they have been excellent. - Jonathon Wood

Everything is perfect with this course. I am watching it for my team and am pretty sure they will love it - Mathieu

I just appreciate all of Gary's work!!!!!! - Karyna

Good explanations, concrete and diverse cases - Mikaidou

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.

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.

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.

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

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 undertsand and remember.

At this moment in time, my videos have been watched nearly half 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.
