The whole point of the course is to teach you how to write effective unit tests using the C# programming language, as well as NUnit as a unit testing framework.
Along the way, we’ll explore concepts related to unit testing. Today, unit testing is an absolutely essential skill and mastery of it is required of every professional developer. Companies assume that developers know how to write unit tests, including all the most important skills such as isolation development and test-driven development (TDD in short). This course does not cover all NUnit features. He’s much more interesting. Learning unit testing gives you a powerful and extremely useful tool.
By understanding unit testing, you can write reliable and easy-to-maintain applications. It is very difficult to work on a project where unit testing is not supported.
