C# and .NET Core Test Driven Development

By: Ayobami Adewole

Overview of this book

This book guides developers to create robust, production-ready C# 7 and .NET Core applications through the practice of test-driven development process. In C# and .NET Core Test-Driven Development, you will learn the different stages of the TDD life cycle, basics of TDD, best practices, and anti-patterns. It will teach you how to create an ASP.NET Core MVC sample application, write testable code with SOLID principles and set up a dependency injection for your sample application. Next, you will learn the xUnit testing framework and learn how to use its attributes and assertions. You’ll see how to create data-driven unit tests and mock dependencies in your code. You will understand the difference between running and debugging your tests on .NET Core on LINUX versus Windows and Visual Studio. As you move forward, you will be able to create a healthy continuous integration process for your sample application using GitHub, TeamCity, Cake, and Microsoft VSTS. By the end of this book, you will have learned how to write clean and robust code through the effective practice of TDD, set up CI build steps to test and build applications as well as how to package application for deployment on NuGet.

Proving unit test results with xUnit.net assertions

xUnit.net assertions verify the behavior of methods under tests. An assertion validates the condition that is expected to be true for the results being expected. When an assertion fails, the current execution of the test is terminated and an exception is thrown. The following table explains the assertions available in xUnit.net:

Assertion

Description

Equal

Validates that an object equals another object

NotEqual

Validates that an object does not equal another object

Same

Verifies that two objects are of the same type

NotSame

Verifies that two objects are not of the same type

Contains

Is an overloaded assertion/method and verifies that a string

contains a given substring or a collection contains an object

DoesNotContain

Is an overloaded assertion/method and verifies that a string

does...
