Question : Which unit test tool contained in Visual Studio 2008?

I have been asked to update my resume describing the unit test tool we used as integrated with the Visual Studio environment.  Could it have been any of these?:

MSTest, NUnit or MBUnit ??

In VS 2008 there is a Test menu which has a few menu items which I used, including a Run menu, a Debug menu and Select Active Test Run Configuration.

Does thisd ring a bell with anyone?  What is the name of this unit test tool?

Please let me know ASAP.
