beef up robustness testing activity per FSO and Aerospace comments

Need to add more info about robustness testing, to include providing invalid inputs.

Could also add some kind of casual inspection of battery usage, to placate those obsessed with battery usage as a security indicator.

is invalid inputs considered 'normal usage'. The requirements says the app should be robust under normal usage.

invalid inputs sounds more like fuzzing and black box testings. Which i'm all in favor of, but it is probably not considered normal usage.

I think the application should be at least robust enough that if a user enters an incorrect username/password etc that it doesn't crash. I don't think the testers should be fuzzing though.

We've removed the robustness requirements and tests so I'm closing this issue.
