A test script is generated in an automated fashion based on a master key file (and optionally, additionally based on user logs) in order to test a software application. The master key file may include one or more scripts of every (or nearly every) possible interaction (e.g., request, presentation, executed action, and so on) a user may have with the software application under test. Often times, the master key file captures each and every request that could be made from a client device to the software application under test executing at a server.
