Start With The Surmountable

Plan


Get a Tool

Plan


• AutoIT is a GUI automation tool that has a simple scripting language and is relatively easy to use

• It’s free• Excellent help file• Strong community - forum and blogs (>850,000 posts)• Short and useful video tutorials • Large function library (>400 functions)• Scripts can be compiled as an executable and run on hosts that do not

have AutoIT installed (or not)

Get Some Help

Roles (architect, testers, supporters)Development best practicesDevelopment assistance for testabilityCode reviewsCommunity

© Synopsys 2013 14

• Refactoring• Debugability (separate branch, traceability)• Source Control• Better code (avoid blind sends/“mouseClick”, set focus

where needed, wait for controls to be available)• Control IDs

Hurdles Overcome - Stability


© Synopsys 2013 15

• Use development best practices– Fix bugs rather than implement kludges– Coding standards– Code reviews (not just with testers)– No recording– No sleeps– Code reuse

• Ask Developers to help troubleshoot• Ask Developers to change application for testability

Hurdles Overcome – Knowledge Transfer


© Synopsys 2013 16

• Bugs found• Replace low-yield manual tests with automation• Extend to other applications• Familiarity• Solve a sticky problem• No insurmountable issues

Hurdles Overcome – Sustainability


© Synopsys 2013 17

• Stable execution• Stable results• Refactoring proven• Found bugs• Replaced low-return manual tests (leaving more energy

for the high-return stuff)• Development changed product for testability• Others used the infrastructure built by the architect• Test suite growing• Extended to other applications

In The End (or is it the beginning?)
