Abstract: Embodiments described herein provide regression testing using artificial intelligence. A regression testing network model for a first plurality of organizations using a common codebase is provided. The regression testing network model provides an organization finite state machine (FSM) model for each organization. A first dataset including samples of the organization FSM models based on regression testing for one or more previous releases of the common codebase prior to a first release of the common codebase is received. A training dataset is generated based on the first dataset. The regression testing network model using the training dataset. A second plurality of organizations for regression testing for the first release is determined, from the first plurality of organizations, using the trained regression testing network model.
