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

There are numerous ways to make unit tests more effective. This includes the following:
- Parameterizing test methods.
- Using a setup method to arrange common data amongst test methods.
- Using multiple test fixtures.
- Testing implementation and the internals of application code, when necessary.
- Pitching test methods at the right level.
- Employing black-box testing by utilizing the test-driven development approach.

There is a series of multiple-choice and true or false questions below. In some multiple-choice questions, only one option is correct, and in others, many may be correct. Ensure that you read the questions carefully before answering them.
