This video explains what Test-Driven Development (TDD) is and how to implement TDD in C#. We will be using VSTS ( visual studio team system) unit testing framework.

We know that effective automated developer testing is a cornerstone of successful app development. In Visual Studio 2012, we have enabled developers to use modern, agile techniques for developing and testing Windows Store apps written in C#/VB. In this talk, we will demonstrate how to apply existing best practices to effectively test your app in this new world. We also explore how to use highly iterative developer testing techniques like Test-Driven Development to create and test your app, using well-known patterns like MVVM and isolation.

TDD is not understood by many developers who use languages such as C# or Java. In this talk, Greg Young will look at TDD again, identify the aspects of these environments that tend to lead to confusion, and then try removing them with hopes of reprogramming developers to a deeper understanding of TDD.

This video provides a code-centric introduction to the concepts, tools, and practices of Test-driven Development (TDD) in .NET. It starts with the basics of setting up a unit testing framework and writing the first test, then it moves on to techniques for mocking dependencies and demonstrate patterns like Dependency Injection that will help you move past testing just the basics.

This video presents the technical challenges that teams discover when adopting TDD difficult and a set of principles for successful TDD. it contains a demonstration of the Testify tool and how to use it to introduce TDD on your own project.
