Ukrainian Processing Center (UPC) ePayment processing chose Web FASTest from Paragon Application Systems, for their ePayment testing platform. UPC selected Web FASTest because it was the only solution that provided a centralized, web-based testing platform for use by UPC customers, vendors and internal users for certification testing, function and regression testing, and development of new ISO 8583 financial message interfaces. Web FASTest is the hub of UPC’s testing and development program. UPC Member Banks conduct online pre-certification testing and online certification using Web FASTest. Outside developers use the software development kit in Web FASTest to develop and test their own ISO 8583 financial message formats. Internal users employ Web FASTest for functional testing and plan to use it for regression testing, stress testing and building detailed testing reports.
