As a professional software tester, embarking on an exploratory testing session for a Mail Order/Telephone Order (MOTO) payments system requires a meticulous and strategic approach. When this system involves a local component integrated with AWS Connect for the crucial task of collecting card details, the complexity and the stakes are notably higher. This guide leverages James Whittaker's renowned testing tours to formulate comprehensive "verify that" checks, ensuring a thorough examination of your MOTO payment solution.
Exploratory testing, by its nature, is about simultaneous learning, test design, and execution. Whittaker's tours offer heuristics or "guide maps" to navigate the software landscape, helping testers to systematically uncover defects that scripted tests might miss. For a MOTO system using AWS Connect, this means scrutinizing every aspect from the agent's interaction with the local system to the customer's experience providing card details via AWS Connect, and the secure transmission and processing of that sensitive data.

MOTO transactions are inherently "card-not-present," which carries a higher risk of fraud. When AWS Connect is used to collect these details, ensuring data integrity (accuracy, completeness) and security (encryption, no sensitive data exposure, PCI compliance) is paramount. This tour directly addresses these risks by focusing on how data is handled throughout its lifecycle in the system.
Can these "verify that" checks be automated? +
While exploratory testing is primarily a manual and cognitive activity, many of the "verify that" checks derived from these tours can inspire or be adapted into automated test cases. For example, API interactions between the local system and AWS Connect, data validation rules, and basic workflow confirmations can often be automated. However, the "exploration" aspect, which involves adapting tests based on observations, remains a human-driven skill.
