Эвристики, мнемоники и другие греческие слова в исследовательском тестировании мобильных приложений
The document discusses the use of heuristics and mnemonics in mobile application testing. It introduces several techniques for experience-based testing including error guessing, checklist-based testing, and exploratory testing. Several mnemonics and heuristics for mobile testing are presented, including SFDPOT (Structure, Function, Data, Platform, Operations, Time), SFDPOTI (adding Interface), SLICED UP FUN, and the Goldilocks Principle for text lengths. Examples are given for how to use these frameworks to guide testing. References for further reading on the topics are also included.
