Visual T# is a unit tests development environment integrated within Visual Studio™, though it can also be used indepedently from it. It is composed of :
* T# : a programming language specific to unit tests. T# is based on the C#™ 2.0 language, which makes it a natural fit for .NET developers. New reserved keywords have been added to simplify the writing of unit tests. It puts a lot of emphasis on unambiguously defining tests' intentions.
* Tools for compiling tests, executing them, testing them and easily navigating amongst them.
