Building Microservices with .NET Core

Overview of this book

Microservices is an architectural style that promotes the development of complex applications as a suite of small services based on business capabilities. This book will help you identify the appropriate service boundaries within the business. We'll start by looking at what microservices are, and what the main characteristics are. Moving forward, you will be introduced to real-life application scenarios, and after assessing the current issues, we will begin the journey of transforming this application by splitting it into a suite of microservices. You will identify the service boundaries, split the application into multiple microservices, and define the service contracts. You will find out how to configure, deploy, and monitor microservices, and configure scaling to allow the application to quickly adapt to increased demand in the future. With an introduction to the reactive microservices, you strategically gain further value to keep your code base simple, focusing on what is more important rather than the messy asynchronous calls.

Tests in action


Until now, 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 tests in action; we will implement tests with the use of:

  • Visual Studio 2017 RC or later
  • .NET Core
  • ASP.NET Core API
  • xUnit and MS tests
  • The Moq framework 

 Getting ready with the test project

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

Note

We created the FlixOne bookstore application in Chapter 2, Building Microservices.

Before we start writing tests, we should set up a test project in our existing application. There are a few simple steps we can take with this test project setup:

  • Using Visual Studio, add a new .NET Core (class library) project to your existing solution
  • You can alternatively use the cli command to add the new project--open the bash command or the Visual Studio command prompt and execute dotnet...
