If you don’t know how much

test coverage you have,

you’ll end up with far too

many test cases!

Not effective enough

Automation levels are low

because of it’s difficult to

automate!

What keeps us from higher

automation levels…

• Prohibitive Maintenance

of Test Scripts

• Missing or inadequate

Object Recognition

• GUI and nonGUI tests require

different teams/skills…

• Autom. Tests require dynamic

and thorough Test Data

Efficiency: Why

are automation

levels so low?

The Maintenance Problem with Capture/Replay

Example:

“…select invoice with the car registration number VIC-3456”

CheckBox Click,

“/usr/cntlCONTAINER/

shellcont/

shell[2]/chbx[1,3]”

Does your business team understand this command?

Is this command stable?

Conclusion: Capture/Replay does not work!
