Test goals should be specific, not general as in "testing if it works".
Some examples of specific goals:
How many band members' names does the user remember?
Can the user make the robot climb stairs?
What classifications does the user make for the chosen verb?
Can the user use FTP to fetch a particular document?
Can the user name the problems involved in teaching a Web course?
Who is invited to join UPE?
What is the purpose of the Fire Safety lab?
(etc.)
