Universal regexp-based mutation tool

Project description

Start on a tool based purely on regexp-specified rewrite of code lines for mutation generation, including multi-language rules aided by special rules for languages or even projects.

HOW TO USE IT

To use this, you should really just do:

pip install universalmutator

then

mutate –help

SIMPLE EXAMPLE USAGE

mutate foo.py

or

mutate foo.swift

should, if you have the appropriate compilers installed, generate a bunch of valid, non-trivially redundant, mutants.

It will, right now, also have the side effect of executing foo.py if it is a script, not a module, many times, and leave some junk files in the directory, just FYI.

MORE INFORMATON

Aim is partly to see how quickly mutation can be applied to new languages, partly how much work of a tool can be offloaded to the compiler / test analysis tools.
