How to ensure a great and consistent user experience? Traditional performance/load tools focus on the back-end, and only measure at the protocol level, thus missing the most critical browser level activity. However, browser level activity is exactly what users want to see and care about! GQP’s User Experience Testing at Scale provides end-to-end; cross browser to back-end, round-trip testing. This approach allows you to simulate dozens to thousands of end-users and capture their experience and test related data, metadata, metrics, and verify real last mile response times. This data is invaluable for insights into the optimization of implemented self-hosted services and applications, as well as for control of SaaS (Software as a Service) providers adherence to promised and contracted SLAs (Service Level Agreements).
