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. After reading this book, you will have a clear understanding of the REST architecture and you can build a web service from scratch.

Chapter 8. API Testing – Guards on the Gates

In the last chapter, we fixed the issues that we had identified and completed the remaining things in our RESTful web service. However, to ensure quality we need to test our endpoints, and manual testing is not enough. In real-world projects, we can't test each endpoint repeatedly because in the real world there are a lot more endpoints. So, we move towards automated testing. We write test cases and execute them in an automated way. In fact, it makes more sense to write test cases first, run them, and then write code to fulfill the requirements that test. This method of development is called TDD (Test-driven Development).

TDD is good and ensures that we are working exactly according to our test cases. However, in this book, we didn't use TDD because there were a lot of things to understand and we didn't want to include one more thing at the same time. So now, when we are done with the concepts, understanding, and writing the RESTful web service...
