摘要
Systems and methods consistent with embodiments presented pertain to the stochastic regression testing of software PDL processors. Test input for PDL processors, which include language processors and raster image processors, may be generated by randomly altering the values of one or more of text, graphical object parameters, image object parameters, graphical combination parameters in an existing PDL input file. In another embodiment, test input for PDL processors may be generated by randomly selecting a first token from a lexical token dictionary and combining the first token with at least one of a plurality of second tokens randomly selected from the lexical token dictionary, so that the combination of the first token and the plurality of second lexical tokens satisfies the syntactical rules for the PDL. In a further embodiment, existing tests in a test pool may split and recombined in a syntactically correct manner to generate new tests.
