Overview of this book

PHP is a beginner-friendly language, but also one that is rife with complaints of bad code,;yet no clean code books are specific to PHP. Enter Clean Code in PHP. This book is a one-stop guide to learning the theory and best practices of clean code specific to real-world PHP app development environments. This PHP book is cleanly split to help you navigate through coding practices and theories to understand and adopt the nuances of the clean code paradigm. In addition to covering best practices, tooling for code quality, and PHP design patterns, this book also presents tips and techniques for working on large-scale PHP apps with a team and writing effective documentation for your PHP projects.

About code coverage

Now we’ve explored the different test types, you probably want to start writing tests right away. But before you put this book away to get coding, let us finish this chapter with the question of how much of your code you should test.

A part of the answer lies within the concept of code coverage, which we already briefly mentioned in Chapter 8, Code Quality Metrics when we talked about code quality metrics. Let us have a closer look at it now.

Understanding code coverage

Code coverage measures the proportion of code that is covered with tests. The higher the code coverage, the better—if there are more tests, the software is less likely to contain bugs, and it will be harder to introduce new ones unnoticed. Higher code coverage is also a possible indicator of better code quality—as we discussed in a previous section of this chapter, tested code must be written in a certain way, which usually leads to better quality.

Generally, the...
