Build a solid foundation in Unit Testing with this course

This course is all about writing effective unit tests using C# programming language and NUnit as a unit testing framework. Along the way we will learn the concepts related to unit testing. Today unit testing is an absolutely required skill from any professional developer. Companies expect from developers to know how to write unit tests including all the most important topics such as mocking and test driven development (TDD in short). This course does not cover all the features of NUnit. This course is way more interesting.

Learning unit testing puts a powerful and very useful tool at your fingertips. Being familiar with unit testing you can write reliable and maintainable applications. It is very hard to lead a project which is not covered by unit tests.

Content and Overview

This course is primarily aimed at beginner developers. It provides solid theoretical base reinforced by tons of practical material.

We start with basics of unit testing. What is a unit test? What unit testing frameworks exist? How to run and debug unit tests. After getting acquainted with the basics we will get to the NUnit framework. Here you'll learn how to install the framework set the runner. Then you'll learn the basics of assertions and arrange-act-assert triplet. Other key features of NUnit are also covered:

• Running tests from the console
• Setup and teardown unit tests
• Parameterized tests
• Grouping and ignoring

Practicing writing of unit tests it's impossible to avoid applying mocks. I like the word test double more in general. By the way you'll learn what the difference between the following notion is:

• Test double
• Fake
• Dummy
• Stub
• Mock

You'll learn how to write test doubles manually. You will also see a simple example of how to use a mocking framework for using mocks. I'll use NSubstitute mocking framework for demonstration.

At the end of this section you'll get acquainted with two key approaches to unit testing Classic or Detroit School and London School of unit testing.

You'll separately learn the basic of test-driven development. It is hard to imagine a modern professional developer who doesn't know about TDD so you'll learn what it is and what it is about. You'll see the Red-Green-Refactor triplet in action.

I could not complete the course avoiding the best practices of writing unit tests. You'll learn the basic concepts of the modern approach to unit testing called pragmatic unit testing. You'll see what problems static classes and singletons bring regarding the unit testing. They make code harder to unit test. After that you'll learn the problem of extracting interfaces just for the sake of introducing shims for injecting dependencies.

You'll know should you write unit tests for the trivial code. You'll learn a lot more in the course.

So in short the course covers the following topics:

• Basic notions of Unit Testing
• NUnit and its basic features
• Test Doubles including fakes dummies stubs spies and mocks
• How to write manual test doubles and how to use a mocking framework
• TDD red-green-refactor triplet
• A great number of best practices of writing unit tests

In the end we will recap what you have learned and you will try to understand where you have to go further with the intention to master your skills.
