You have probably tested software before. If you have not, don't worry: this chapter will cover all you need to know about testing microservices. But in all likelihood, you have run your own software before, which is the most basic kind of testing. Different kinds of testing tools allow us to make sure that software is doing what it should. After reading this chapter, you will have a basic understanding of how to test server-side Swift applications and specifically microservices. Testing microservices is different from testing a monolithic application as defined in Chapter 1, Introduction to Microservices. Instead of just testing one application, you need to test every service and—and this makes it so special—the services working together. If, for example, three microservices are working together, an error in one of them might cause the...
Hands-On Swift 5 Microservices Development
Hands-On Swift 5 Microservices Development
Overview of this book
The capabilities of the Swift programming language are extended to server-side development using popular frameworks such as Vapor. This enables Swift programmers to implement the microservices approach to design scalable and easy-to-maintain architecture for iOS, macOS, iPadOS, and watchOS applications.
This book is a complete guide to building microservices for iOS applications. You’ll start by examining Swift and Vapor as backend technologies and compare them to their alternatives. The book then covers the concept of microservices to help you get started with developing your first microservice. Throughout this book, you’ll work on a case study of writing an e-commerce backend as a microservice application. You’ll understand each microservice as it is broken down into details and written out as code throughout the book. You’ll also become familiar with various aspects of server-side development such as scalability, database options, and information flow for microservices that are unwrapped in the process. As you advance, you’ll get to grips with microservices testing and see how it is different from testing a monolith application. Along the way, you’ll explore tools such as Docker, Postman, and Amazon Web Services.
By the end of the book, you’ll be able to build a ready-to-deploy application that can be used as a base for future applications.
