– text– value– ID– tooltip

• Image• Coordinated• Index (last resort)

• Any criteria which could be written in java code

Lookup principles

UI test

• Customize ...– Curve attributes– View attributes

• Verify image• Generate code• Verify code• Start animation• Verify animation

Waitings

Every UI action takes time

• Wait for everything– Window appearance– Label change– Image appearance– Property change– File update

• Configurable timeouts

• Exceptions

TD + *TS NR

TM * NR NC*EA =

NC*

TM – time needed to run the tests manually

TD – time needed for automated test development

TS – time needed for automated test support

NR – number of test runs

NC – number of tested configurations

Test automation effectiveness

42

What about record&replay?

• Pretty low TD

– Pretty much the same as TM

… but ...

• High TS

– Generates unmaintainable code– No test code encapsulation

43

Ideal test

• Lives forever• Written in terms of domain model• All the UI logic is hidden within a library

• Benefits– Low load on tested UI– Ability to run on low-end devices

• Limitations– Two-part code– Lookup is only through properties– Slow
