Leveraging WTASTM for Green Benefits and Managing Your Test Lab Enviroment Challenges. Until now, many challenges in managing heterogeneous test lab environments could not be overcome with virtualization, due to technology limitations. Companies were forced to use tools for a virtual environment only. Wipro has developed a new solution (Wipro Test Automation Services Framework) that cuts across both virtual and non-virtual environments. It not only resolves all the issues associated with managing a test lab environment but also optimizes the environment and aligns with a green IT strategy.
