Verifying Basic SQL Functionality

I've been asked by my manager to come up with a script to run before and after an upgrade of SQL server to verify that basic statements within SQL work before and after an upgrade. Here's what I came up with. Anyone else ever do something like this? 

/*
SQL Standard Health Check
DBA : Amy Boyd
Date: 10/5/2006

This is a script that can be run prior to and after the upgrade of
SQL server components to verify basic functionality.
