“Persona Based Holistic Testing”
summary
Persona-based holistic testing claims it catches system-level gaps that modular tests miss, arguing it could have prevented the Mars Climate Orbiter ~$327M failure by spotting unit mismatches. A concrete retail example expands a simple discount module into multiple flowcharts when personas like shopaholic, cart abandoner, product returner are considered; inputs grow to include user data, date/time and reuse counts. Tests are implemented as Postman collections driving those persona scenarios end-to-end.
