Tests in action

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 tests in action; we will implement tests with the use of the following:

• Visual Studio 2017 Update 3 or later
• .NET Core 2.0
• C# 7.0
• ASP.NET Core 2.0
• xUnit and MS tests
• The moq framework 

Getting ready for 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.

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:

1. From Solution Explorer within Using Visual Studio, right-click on Solution and click New Project—refer to the following screenshot:

2. From the Add New Project template select .NET Core and xUnit Test Project...
