Mercury Interactive Corp has tinkered with its WinRunner and LoadRunner test tools and come up with versions of both that can test SAP AG’s R/3 applications suite. The major change to the programs is a set of revisions that enables them to read R/3 scripts, which use a proprietary object architecture that most test tools simply can’t recognize, the Sunnyvale, California- based company said. The NT versions, scheduled for release by the end of March, let R/3 users predict system performance, verify functionality and test scaleability as application modules and users are added to an R/3 installation. WinRunner is a test development environment to generate R/3 test scripts. LoadRunner is a load-testing tool that exercises a system with hundreds or thousands of virtual users to identify potential bottlenecks before a system goes live. WinRunner for R/3 is $5,000, LoadRunner for R/3 starts at $50,000 for 50 virtual users. Both run on either Window NT or on Windows 95.
