Forrester evaluated leading functional testing solutions — tool suites with support for manual testing, test automation, and test management — across 87 criteria. Our research revealed Mercury Interactive to be the sole Leader in this market, thanks to its relentless focus on environment support and ease of use. IBM follows Mercury as a Strong Performer, with especially notable manual testing capabilities and the best test automation tool for users with programming skills. Borland Software and Compuware are both Strong Performers — but just barely. Our evaluation also included Empirix, which has a less full-featured solution overall than the other vendors we evaluated and which supports test automation in Web environments only.
