In the software world, particularly in the world of SAP with the promise of data and process integration among modules, a single change to an area of the system may cause "side effects" on previously working system functionality. Many factors trigger changes and upgrades in a live SAP system (i.e., applying OSS [On-line Service System] notes, graphical user interface [GUI] upgrades, etc.).

Automated test tools facilitate and expedite the execution of test cases for regression testing. Despite the promise of implementing an effective automation framework with commercial test tools as a means to support testing of SAP production changes, many SAP projects struggle to do so.
