To supplement Sunny D's answer. - Internationalization Testing ( currencies/symbols, display of decimal points and splitting of large numbers by commas or such, anything else that is region specific but not covered by the translations in localization ) - Accessibility Testing ( for the fully blind, the deaf, the various forms of colorblindness, display flicker liable to induce gran-mal seizures, etc. ) - Safety ( will it tip over and crush somebody, if someone smashes the front in with a crowbar will there be wicked-sharp shards of glass, etc. ) - Legal Compliance Testing ( does it specifically meet each and every pertinent clause and item in local ordinance/laws? )

I don't remember it was one of many questions.
