Microsoft Test Manager 2013 has been enhanced to embrace exploratory testing (sometimes called agile testing), which allows you to explore the product in any way you want while keeping relevant steps and data that can be used to directly file bugs and feedback. Lab Management has also been greatly simplified with the consolidation of agents and the introduction of standard environments, which allow you to benefit from build-deploy-test workflows without the dependency on Hyper-V or SCVMM. With Visual Studio, Microsoft now provide the ability for you to include additional adapters to support 3rd party unit testing frameworks such as xUnit.net, NUnit, and others. The new Test Explorer will showcase all of the tests across your solution regardless of which testing framework they were written for. Visual Studio will continue to provide support for traditional unit tests written using the classic Visual Studio Unit Testing Framework, and adds support for writing tests in C++ as well.
