Most code generated for these two UnitTest frameworks is very similar. The main differences are:
Team Test use different attributes with NUnit in test class, such as [TestClass()] to [TestFixture] and [TestMethod()] to [Test] etc.
AllTests file is not generated because all tests will be run in Visual Studio gui or command prompt.
Log4net is replaced by test result .trx file that can be opened in Test Result window in Visual Studio.
