Reduce testing effort Automate things that can be automated

Tests should be◦ Repeatable (Reliable)◦ Maintainable◦ Fast

AJAX Web 2.0 Highly dynamic applications Lots of frameworks Newer, powerful browsers HTML5

Object IdentificationHandling AsynchronicityEvent SimulationReportingPlayback time optimization

Present methods◦ Id, name◦ Xpath◦ Css-selector

Xpath and Css-selectors are brittle◦ Too dependent on programmatic structure◦ Require programmatic knowledge

Business logic changes less than code Business drives User Interface

UI Relations◦_image(“plus.gif”, _near(_div(“My Documents”)))◦_textbox(0, _near(_label("Loan Amount")))◦_cell(0, _near(“Ram”), _under(“Loan Amount”))

More stable

Waits needed for◦ Page loads◦ Frame/iframe loads◦ AJAX request completion◦ Javascript timeout triggers

Hard coded waits◦ Wasteful

Conditional waits◦ Complicated

Tool should handle time outs automatically

Easy to create scripts◦ Good recorders on all browsers◦ Object Spy

Easy to debug scripts◦ Real time debugging to examine state of web page◦ Good reporting

Work across browsers and operating systems

Execute tests in parallel◦ Some Browsers allow separation of cookies across

instances Spread tests across machines Limit hard coded waits Use fast accessors
