MANUAL TESTING & DEBUGGING
MANUAL TESTING ON HARDWARE

-FOCUSABLE -LABELED -TRAITS
-ACTIONABLE -STATE -CONTEXT
VOICEOVER
MAKING THE MOST OF MANUAL TESTING
RATHER THAN TESTING EVERY ELEMENT ON THE SCREEN,
TEST A FEATURE FROM START TO FINISH.
SIMPLIFY ELEMENTS: GROUP ITEMS & MAKE LARGER TAP
TARGETS.
NOTHING IS BETTER THAN MANUAL TESTING.

DESIGN PHASE.
ACCESSIBILITY IS NOT A FEATURE, EVERY FEATURE SHOULD BE
ACCESSIBLE.
IF IT’S NOT ACCESSIBLE, IT’S NOT DONE.
MAKE TESTING FOR ACCESSIBILITY PART OF
YOUR TEST PLAN.
GET REAL USERS INVOLVED!
GET BETA TESTERS WHO USE A VARIETY OF
ASSISTIVE TECHNOLOGIES.
THINGS TO REMEMBER
KNOW YOUR VOICEOVER GESTURES!
DON’T LET THE SIZE OF WORK DISCOURAGE YOU FROM STARTING IT.
REDUCING COSTS•Move most Accessibility work to design phase •Focus on testing the right things •Work incrementally •Prioritise most important features
DON’T WORRY ABOUT WHAT A USER CAN’T DO. FOCUS ON WHAT THE TECHNOLOGY CAN DO.
