Abstract: Disclosed are a method and system for performing regression tests in a computer-based product or service fulfillment management system. Generation of regression test packages is accomplished by collecting fulfillment activity data, defining a set of criteria to assess the collected fulfillment activity data, evaluating the collected fulfillment activity data based on the set of criteria, and defining objectives for the generation of regression test packages. Based on these objectives, regression test packages are generated and a regression test is run using these test packages. Thus regression test packages can be provided automatically and dynamically preferably based on actual fulfillment data from a general ledger, according to several criteria such as occurrences, revenue/profit of order/contract types, material classes, customer classes, etc.
