Centerline Software Inc, Cambridge, Massachusetts claims its QC/Advantage software quality testing system is the first open system to test right through the lifecycle, rather than just at the end of the development cycle. The testing system comprises of a uniform user environment, object-based test foundation, distributed test designer, parallel execution executive, consolidated results analyser and an open integration system. QC/Advantage will be released at the end of the month on Sun Microsystems Inc’s SunOS and Solaris for Sparc and UltraSparc and Hewlett-Packard Co’s HP-UX on HP 9000. It also supports Microsoft Corp Windows 3.1, Windows95 and Windows NT clients. Support for IBM Corp’s AIX will come later on in the summer with other Unixes and a full Windows NT implementation after that. The starter pack with five licenses is priced at $38,000, with add-on licenses available at volume discounts, Centerline said.
