A new Eclipse plugin in SilkPerformer allows performance test development to be done within the Eclipse IDE.

SilkTest adds support for Windows Vista so users can test applications developed for Vista at the UI level.

"Every single testing vendor really needs to have support for Vista because one of the things that Vista introduces is the need to retest your applications," when migrating from other platforms, Schwaber said. "Our data show that people will be doing these migrations for the next couple of years."

Other environments supported by SilkTest include Windows XP 64-bit operating systems, Internet Explorer 7.0, and .Net.

SilkCentral Test Manager starts in price at US$1,700 per named user, while SilkTest pricing begins at $4,500 per named user. SilkPerformer prices begin at roughly $10,000 per user.
