Hands-On Microservices with C# 8 and .NET Core 3 - Third Edition

By: Gaurav Aroraa, Ed Price

Overview of this book

<p>The microservice architectural style promotes the development of complex applications as a suite of small services based on specific business capabilities. With this book, you'll take a hands-on approach to build microservices and deploy them using ASP .NET Core and Microsoft Azure. </p><p>You'll start by understanding the concept of microservices and their fundamental characteristics. This microservices book will then introduce a real-world app built as a monolith, currently struggling under increased demand and complexity, and guide you in its transition to microservices using the latest features of C# 8 and .NET Core 3. You'll identify service boundaries, split the application into multiple microservices, and define service contracts. You'll also explore how to configure, deploy, and monitor microservices using Docker and Kubernetes, and implement autoscaling in a microservices architecture for enhanced productivity. Once you've got to grips with reactive microservices, you'll discover how keeping your code base simple enables you to focus on what's important rather than on messy asynchronous calls. Finally, you'll delve into various design patterns and best practices for creating enterprise-ready microservice applications. </p><p>By the end of this book, you'll be able to deconstruct a monolith successfully to create well-defined microservices.</p>

Testing the microservice application

So far, we have discussed test strategies and various types of microservice tests. We've also discussed how to test and what to test. In this section, we will see some tests in action. We will implement these tests, with the following minimal requirements:

  • Visual Studio 2019
  • .NET Core 3.1
  • C# 8.0
  • xUnit and MS tests
  • The moq framework 

Getting ready for the test project

First, we will test our microservice application, the FlixOne bookstore. With the help of some code examples, we will learn how to perform unit tests, stubbing, and mocking.

We created the FlixOne bookstore application in Chapter 2, Refactoring the Monolith.

Before we start writing tests, we should set...
