eth-mutants

eth-mutants is a mutation testing tool for Solidity contracts.

Installation

npm install eth-mutants

Usage

The `preflight` command will show the number of possible mutations found
and print some compact diffs for each mutation. Use this to understand
how long it may take to visit all mutations and please report any invalid 
ones.

The test command will start applying mutations and running your tests to check if they pass. It will report the result of each mutation.

eth-mutants test

This tools makes some important assumptions about your workspace, which should hold true for most Truffle-based projects, but I plan on adding options to override them soon:
Your contract files are in the contracts/ directory You run your tests with npm test which returns a non-zero error code in

case of failure.

Mutators

The only mutation implemented at the moment is called boundary-condition and replaces < adn > for <= and >= and vice-versa. Contributions for mutators are especially welcomed.
