Wow. I am really, really underwhelmed at this production. You ... made a class, marked it as a TestClass, and made a test, and annotated it as a TestMethod.
That's IT? after almost a year, the only difference I see between what your extension produced & what I got from the Unit Test template is the addition of Assert.Fail() in the TestMethod.
For anyone who liked the old functionality (you, know the FUNCTIONAL functionality), here is a post about how to re-enable that menu option.
