vertigo-rs

Introduction

This is an actively maintained fork of Joran Honig's vertigo with support for foundry added.

This tool will mutate files in src/ and run forge test to see if the mutant survives. Files that end with .t.sol or have test in their name (including the path) are ignored. Files in lib (or any directory that isn't src/) will not be mutated.

You do not need to specify that you are in a foundry project, the presence of a foundry.toml file will signify to this tool that you are in a foundry repo. If you have configuration files for truffle or hardhat in your project, this tool will get confused. You can temporarily change their names.

git clone https://github.com/RareSkills/vertigo-rs
cd vertigo-rs
python setup.py develop

cd <your foundry repo>

python <path-to-this-project>/vertigo-rs/vertigo.py run

cli arguments

--src-dir <contracts-directory>

Changing the source directory. This is usually src/ by default in foundry, but if you have a different name like contracts you can specify it with --src-dir. Default is src/

--exclude-regex <regex>

Don't test files in --src-dir that match this regex. This is useful if you have mocks or tests in a subdirectory of src/

--scope-file <file>

Mutate only the files specified in the provided scope file, where each line should list one file path relative to the project root. This option supersedes --src-dir. It is useful if you would like to target a select group of files

--sample-ratio <float [0-1]>

Don't run every mutation, but run a percentage of them. Useful if you are just checking if everything works end-to-end

--output <file>

Save output to a file instead of stdout. Some terminals don't show the output, so use this option if you don't see an output. Recommended to use generally. Defaults to stdout.

Please see the original readme for the other options, or use the --help option to see the rest.
