ABSTRACT:
The testing of driver output is automated. Embodiments of the invention filter out data that is known to change between two similar outputs of a driver. By filtering this dynamic data out, the remaining data can be compared to known-good data to identify any variations which would appear in a physical manifestation (e.g., a printout) of the data.
