This is the testclass I use for our Triggers, so I just added to the end of it. The testMethod newAccountpage_Test is the first one I created and got to work without errors or problems, but it doesn't list my controller extension in the Code Coverage after I run the tests. I am assuming that if the test of my controller went successful it would list in  the Apex Test Runner mycontroller2 (ApexClass) # of lines tested, 100% covered. Correct?

The last one, testMyController is where I started down different path from a post I found but it doesn't work because I don't have a Save Method in my Controller, but I was starting to think I could Edit the page's Account description  then somehow call the built in Save button. But this is defintely confusing.
