Overview of this book

REST is the most wide spread and effective standard to develop APIs for internet services. With the way PHP and its eco-system has modernized the way code is written by simplifying various operations, it is useful to develop RESTful APIs with PHP 7 and modern tools. This book explains in detail how to create your own RESTful API in PHP 7 that can be consumed by other users in your organization. Starting with a brief introduction to the fundamentals of REST architecture and the new features in PHP 7, you will learn to implement basic RESTful API endpoints using vanilla PHP. The book explains how to identify flaws in security and design and teach you how to tackle them. You will learn about composer, Lumen framework and how to make your RESTful API cleaner, secure and efficient. The book emphasizes on automated tests, teaches about different testing types and give a brief introduction to microservices which is the natural way forward.

Types of testing

There are different types of testing in different contexts. In our case, we will discuss major types of automated testing. These are the different types, based on how and what we test:

  • Unit testing
  • Integration testing
  • Functional testing
  • Acceptance testing

Unit testing

In unit testing, we test different units separately. By unit, we mean very independent components. Obviously, components depend on each other we consider a very small unit. In our case that small unit is class. The class is a unit that should have a single responsibility and it should be abstract from others and depend on the minimum number of other classes or components. Anyway, we can say in unit testing, we test class by creating an object of that class irrespective of whether it fulfills the required behavior.

One important thing to understand is that during unit tests, our test shouldn't touch code other than class/code under testing. If this code is interacting with some other object or external stuff during...
