  • a) recording detected application events into a playback event file, said application events originating from a presentation layer and passed to an application layer of a first version of a software program;

    b) recording a first response of said first version of said software program to said application events and storing said first response in said computer readable memory;

    c) replaying said playback file and directly applying said application events stored therein to an application layer of a second version of said software program;

    d) recording a second response, said second response being a response of said application layer of said second version of said software program to said application events recorded by step a); and

    e) determining differences between said first and second versions of said software program by comparing said first response and said second response and determining differences therein.
