Usage: perl GPFuzz.pl <N> <grammar-file> <root-rule> "<parser>" "<fail-msg>"

GPFUZZ generates N distinct inputs, valid according to a grammar-file. Then, it executes these inputs on the parser and produces a bunch of txt files containing performance statistics.

Please download mutrex.jar first!

perl GPFuzz.pl 1000 original.bnf regexp "timeout 60 java -jar mutrex.jar" "Exception"

To execute the input generation with problematic construct avoidance:

perl GPFuzz.pl 1000 avoidance.bnf regexp "timeout 60 java -jar mutrex.jar" "Exception"

To generate 10 inputs for the toy grammar:

perl GPFuzz.pl 10 toy.bnf e "echo" "NoFail"
