4. INTENTION
To develop a GUI-Testing
framework, that can not only
test Smalltalk internal GUI, but
external processes as well.
It should be usable within SUnit
tests.

5. Record and Replay Events
©2015 Cincom Systems Inc. All Rights Reserved.5
Record all events (keyboard, mouse) with timing.
Events can be saved to a file and replayed later.
Beware of applications, that save the state in
between, e.g. Calculator

Advantage:
• What-You-See-Is-What-You-Get
Drawback:
• Uses absolute coordinates
• Recording has to be redone, if the test changes
even the slightest bit
