Unit tests need to be created that tests obfuscating with all possible Mutator permutations that are 2 Mutators long. So basically given the dozen or so current Mutators, make sure Mutators don't just work on their separately, but together as well. I've run into a few random cases where using Mutators in specific combinations produces faulty payloads, and want a test that can do this for me.

Using the existing single mutator test in the test/ folder as a template should work. I would assume that you could take that test, add Mutator permutation logic (probably using itertools) to the beginning, and loop through every permutation and test it. An extra call to obfuscationHandler.genObfuscationLayer is needed, but overall pretty simple task.
