Abstract: An enterprise test system includes a plurality of probes inserted at various locations in the enterprise system for recording data from system components during teach mode. During playback mode, the recorded data is used to exercise the system as probes collect actual data for comparison to expected data. In one embodiment, data from actual user transactions is recorded by the probes. The recorded data can be expanded to load test a component using recorded transaction data. In one embodiment, the recorded data can be used to load test a component under test without compiling test code.
