[Guruji]:- User interface attack # 8
Force invalid outputs to be generated
· Similar to attack #7, but focusing on invalid outputs
· One key ingredient is often input sequencing to generated the invalid output
· Example: Feb 29, 2001 possible on Windows NT date/time clock if Feb 29 selected on a valid date (leap year) then change year to 2001
User interface attack # 9
Force properties of an output to change
[Continued in the next day’s post]· Gives testers a way to think about persistent outputs; outputs that hang around on the screen or file can be updated in ways to break the software
· How to conduct: Set properties to one value, then try changing to something else
