There are a few ways to run unit tests in Visual Studio - in each case the same tests are run, so the best option for you will depend on what tools you already have installed and how interested you are in setting yourself up to run tests frequently.
As of Visual Studio 2012 there is a built-in, extensible unit test runner that NUnit can integrate with. The NUnit project for VistaDB includes the necessary adapter to work with VS 2015 and later.
