Case Study: HollyFrontier achieves rapid, accurate SAP test automation (95% invoice net‑value accuracy) with Worksoft Certify Suite

Lessons Learned From Test Automation at Holly Corp

Holly Corporation, a publicly traded refining and marketing company (with Holly Energy Partners), faced continual SAP and business change — service packs, acquisitions and a major 2010 consolidation of marketing and crude procurement — that created huge master‑data impact and tight test windows. The company needed reliable end‑to‑end validation of critical processes, reproducible test data, and rapid execution without relying on developers, all while meeting a hard go‑live deadline of January 1, 2011.

Holly implemented Worksoft Certify and ran a focused automation effort staffed by five functional SAP analysts and a Worksoft consultant. Over two weeks they executed roughly 12,000 transactions, met required invoice accuracy, hit the go‑live date with no adverse impact to cash flow or financial reporting, eliminated developer scripting, and produced reusable test components for future testing.
