A non-limiting example of a computer-implemented method includes receiving, by a processing system, application data from a user processing system deploying utilizing an application during normal use of the application. The method further includes generating, by the processing system, a regression test scenario for a new version of the application to be deployed on the user processing system, wherein the regression test scenario is based at least in part on the application data received from the user processing system. The method further includes performing, by the processing system, a regression test on the new version of the application using the regression test scenario. ## Claims ### Claim 1 A computer-implemented method comprising: receiving, by a processing system, a history log comprising application data from a user processing system utilizing an application during normal use of the application, a customized application setting for the application, an amount of data used by the application, a processing requirement for running the application, and a current system state; determining, by the processing system, a pattern of use for the application based on the history log; generating, by the processing system, a regression test scenario for a new version of the application to be deployed on the user processing system, wherein the regression test scenario is based at least in part on the pattern of use for the application data received from the user processing system;
