Reviews

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.
