Usability Testing with Cognitive Walktrough KORONA Point of Sales

Abstract

This study tests the KORONA POS software in sales transaction scenarios and integration with printers using functional testing methods. The sales transaction testing involves several steps including selecting product categories, deleting items, changing item prices, canceling receipts, logging out, and displaying total payments. All steps were successful as expected, except for invalid inputs which caused the system to fail in providing notifications for unregistered items. Hardware integration testing examines printer connectivity and receipt printing capability. With the initial condition of the printer being on, the device successfully read the connected printer and printed receipts as expected, demonstrating success in integration and printing functions. The testing also includes a scenario where the printer driver is not connected, in which the KORONA POS software successfully provided a notification that the driver could not be connected, ensuring the system responds correctly. The results of these tests indicate that KORONA POS performs well under standard operational conditions but needs improvements in handling invalid inputs to enhance overall system reliability.
