Scream Testing

I came across an interesting method of testing, but not to find defects. Instead, scream testing can be used to determine if some hardware or a service is being used or not:

…we put these servers into a scream test environment where they still have access to our corpnet, but users are now limited from doing just about anything on the machines except logging in.  If someone does log onto a machine to try something (like running tests, installing other software, etc.), a dialog pops up telling them that this machine is in a scream test and they need to contact my lab managers if they want access back for this server, otherwise it will be retired in so many days.  We usually put a set of servers in a scream test for 2-4 weeks.  Some people on the team will scream profusely and we are happy about that.
