Industry, employers, startups, and amateur developers are increasingly looking towards unit testing their software. Unit testing is one of the most reliable ways to find and keep software bugs at bay, thus reducing costs and development pains. Developers working with the .NET framework are overwhelmingly turning to NUnit to meet their unit testing needs.

In this course, you’ll learn the principles of unit testing, and in the process, learn to configure and use the NUnit testing framework. Given that the course places an emphasis on principles, these skills are transferable to other unit testing frameworks. Alongside these, you’ll also get hands-on experience with projects and exercises that provide ample opportunities to learn how to design effective tests in the NUnit framework.

At the end of the course, you’ll be able to quickly write unit tests that maximize logical coverage, test complex applications, and better organize your testing projects—setting you up as a natural leader in your organization.

Mastering Unit Testing Principles with NUnit

# Introduction

Assertions are the engine of test cases. NUnit provides two ways to articulate assertions. One approach is classical assertions, and another is constraint assertions. Both work equally well, with constraint assertions having a more fluent syntax. 

We will present a series of multiple-choice and true or false questions. Some multiple-choice questions have one correct answer and others may have many. Ensure that you read the question carefully before answering it.

# Quiz
