A data processing system, method, and program including an automated software test environment are disclosed for automatically testing a software application. A work flow manager is established for automatically managing the automated software test environment. The automated software test environment includes multiple computer systems coupled to a server computer system utilizing a network. The work flow manager is executed utilizing the server computer system. Multiple ordered test phases are established. At least each of two of the order test phases are executed utilizing different ones of the computer systems. An event is transmitted to the work flow manager utilizing one of the computer systems to start execution of selected ones of the ordered test phases. The work flow manager controls execution of the selected ordered test phases in response to the receipt of events.
