1. A system comprising: a processor programmed to initiate executable operations comprising: receiving a first version of an automation script configured to execute in a first framework and expected unit test results for the automation script; automatically creating a second version of the automation script from the first version of the automation script, the second version of the automation script configured to execute in at least a second framework; executing the first version of the automation script in the first framework to run a first version of a unit test and executing the second version of the automation script in the second framework to run a second version of the unit test; comparing at least a first output generated by the first version of the automation script running the first version of the unit test and at least a second output generated by the second version of the automation script running the second version of the unit test to at least one expected unit test result to determine whether the first output and the second output correlate with the expected unit test result; and responsive at least to the first output and the second output correlating with the expected unit test result, determining the second version of the automation script is valid.
