Modular Programming with PHP 7

By: Branko Ajzele

Overview of this book

Modular design techniques help you build readable, manageable, reusable, and more efficient codes. PHP 7, which is a popular open source scripting language, is used to build modular functions for your software. With this book, you will gain a deep insight into the modular programming paradigm and how to achieve modularity in your PHP code. We start with a brief introduction to the new features of PHP 7, some of which open a door to new concepts used in modular development. With design patterns being at the heart of all modular PHP code, you will learn about the GoF design patterns and how to apply them. You will see how to write code that is easy to maintain and extend over time with the help of the SOLID design principles. Throughout the rest of the book, you will build different working modules of a modern web shop application using the Symfony framework, which will give you a deep understanding of modular application development using PHP 7.

Unit testing

We now have several class files that are not related to the controllers, meaning we can run unit tests against them. Still, we won't be going after a full code coverage as part of this book, rather focus on some of the little-big things, like using containers within our test classes.

We start of by adding the following line under the testsuites element of our phpunit.xml.dist file:

<directory>src/Foggyline/CatalogBundle/Tests</directory>

With that in place, running the phpunit command from the root of our shop should pick up any test we have defined under the src/Foggyline/CatalogBundle/Tests/ directory.

Now let's go ahead and create a test for our Category service menu. We do so by creating an src/Foggyline/CatalogBundle/Tests/Service/Menu/CategoryTest.php file with the following content:

namespace Foggyline\CatalogBundle\Tests\Service\Menu;

use Symfony\Bundle\FrameworkBundle\Test\KernelTestCase;
use Foggyline\CatalogBundle\Service\Menu\Category;

class CategoryTest...
