• Erittäin vaihteleva suoritusnopeus– Toteutuksien erovaisuudet– Prosessorien nopeuserot

• Ruudun koko vaihtelee• Syöttölaitteet vaihtelevat

– Näppäimistö, hiiri, kosketusnäyttö– Tulevaisuudessa ehkä mikrofoni, GPS, kamera, ..

• Muistin määrä vaihtelee merkittävästi• Verkon nopeus ja latenssit erilaisia

Example: SimpleDevelopment Model

• Application is created by extendingcom.itmill.toolkit.Application

• init() gets called on application start– Initializes the user interface– Registers event handlers

• Events arrive to buttonClick(event)– Calculations are done in the

handler to keep the examplesimple

– Event handler updates calculatordisplay with a simple method call

• No XML, HTML or JavaScript,just Java

buttonClick(event)

init()

Testing Tools

1. Record a test case– Use application like normal user

would– Add assertions to verify correct

application behaviour / results

2. Save test case to testing server– Combine test cases to complete test

suites– Edit test if modifications are needed

3. Run test case on any browser– Run tests regularly to ensure quality– Run several tests in parallel to

ensure application scalability– Run the tests in all target browsers

and operating systems
