Applications are evolving at an ever-faster pace. These applications are not discrete islands; they build on a complex, interconnected set of components that includes disparate technologies, developers, deployment topologies and organizations. Developers must deliver high-quality applications while limiting their testing expenses. In this challenging environment, a combination of automated integration testing and test virtualization can enable test teams to improve software quality and keep up with the rate of change. This whitepaper helps address these needs by describing the benefits that can be gained through a proactive and continuous approach to integration testing with IBM® Rational® test automation solutions.
