C# Unit Testing with xUnit

7 Courses
13 Hours
Skill IQ

Unit testing has become standard practice for today's software developers and xUnit is one of the most popular unit testing frameworks available for .NET. The goal of this learning path is to help you understand how to write clean, testable code, all the way from writing your first test to mocking out dependencies to developing a pragmatic suite of unit tests for your application.

Beginner

The courses in this section will help you master the basics of writing unit tests. First, you will learn how to use xUnit, one of the most popular unit testing frameworks used in .NET. Then you will learn how to use Moq, a mocking framework which allows you to replace dependencies in your code when you write tests. Mastering these two frameworks will help you create unit tests for a wide-ranging set of scenarios you encounter when writing code.
