TAO is a tool from SAP that automates the creation of test components from SAP transactions and business processes and uploads them to HP Quality Center. It aims to accelerate testing and facilitate moving from manual to automated composition-based testing. TAO analyzes business processes and user interfaces in SAP systems and generates reusable test components. It helps reduce testing costs and risks for system changes and upgrades. TAO works together with Quality Center to generate test cases from the components and facilitate running and tracking test execution.
