RESUMEN

The availability of testing infrastructure is a major factor in product development project costs. Software virtualization is a powerful mechanism for simulating a test setup on a few desktops that would otherwise require "real" equipment. It has shown a savings of about 30 percent of overall product development costs by executing 80 percent of unit testing and 25 percent of grey- and black-box testing in the desktop environment. Both open source and commercial products are available to support it.
