Manticore and Echidna scripts for testing μFragments.
We have included a Dockerfile to set up and install the necessary versions of Manticore, Echidna, Solidity, and their associated dependencies.
$ docker build -t fragments-test .
$ docker run -it fragments-test
fragments@e31e5c314e2b:~$ cd echidna/
fragments@e31e5c314e2b:~/echidna$ ./run_echidna.sh
fragments@895f6f8a5476:~$ cd manticore/
fragments@895f6f8a5476:~/manticore$ python3 add_and_remove_source.py
This script formally validates that there is no way for the whitelist to be corrupted.
There is also a script gons_invariant.py that can be run similarly that validates the invariant that _gonsPerFragment always equals TOTAL_GONS.div(_totalSupply). An incompatibility in Manticore 0.2.2 means that this script will fail due to an out of gas error, however, this will hopefully be fixed in the forthcoming release of Manticore.
