Practical Microservices

Overview of this book

<p>A microservice architecture helps you build your application as a suite of different services. This approach has been widely adopted as it helps to easily scale up your application with reduced dependencies. This way if a part of your application is corrupted, it can be fixed easily thereby eliminating the possibility of completely shutting down your software. This book will teach you how to leverage Java to build scalable microservices. You will learn the fundamentals of this architecture and how to efficiently implement it practically.</p> <p>We start off with a brief introduction to the microservice architecture and how it fares with the other architectures. The book dives deep into essential microservice components and how to set up seamless communication between two microservice end points. You will create an effective data model and learn different ways to test and deploy a microservices. You will also learn the best way to migrate your software from a monolith to a microservice architecture.</p> <p>Finishing off with monitoring, scaling and troubleshooting, this book will set a solid foundation for you to start implementing microservices.</p>

Preface

Chapter 6. Testing Microservices

An increase in the number of microservices in a platform will increase the DevOps work exponentially. In this situation, automation will take the lead, bringing challenges in automation testing. Unlike in monolithic applications, it is not straightforward to test microservices. As microservices can receive API calls from many other microservices and make calls to other microservices, testing a microservice in isolation is tricky with integration testing. It requires a considerable amount of effort to plan microservice testing. In this chapter, we will go through some techniques that we can use to test a microservice.

We will cover the following topics in this chapter:

  • The purpose of testing in the microservices world
  • Unit tests
  • Integration tests
  • Component (service) tests
  • Contract tests
  • End-to-end tests
