A computer system includes a processor. The processor is configured to provide a documented screenshot and a machine-executable indication of steps which generated the documented screenshot as contained in documentation. The processor also will execute the steps which generated the documented screenshot, to generate a current screenshot. The processor also will compare the documented screenshot as contained in the documentation to the current screenshot generated by executing the steps, to provide a determination whether the comparison shows differences between the documented screenshot and the current screenshot. A method according to the above will detect changes to a screenshot used in documentation. A non-transitory computer-readable medium can perform a method to detect changes to a screenshot used in documentation.
