2. Current Issues
GUIs are difficult to test directly in code.
Our testing procedure consists of manually clicking
through as many common tasks as possible.
We aren’t confident enough idea whether things are
working or not before a release.
Bugs are sometimes hard to explain and reproduce.
No good automation tools available on OS X... until

8. Goals
Think about how you can leverage automation.
Get comfortable writing and running test scripts.
Become experts in Sikuli, able to write modular and
reusable scripts.
Use Sikuli scripts to demonstrate bugs.
Use Sikuli scripts as our official test specifications.
Develop better, more reliable software.
