Regression build for ESLint
eslint-canary clones a hardcoded list of projects known to use ESLint, and runs ESLint on all of them to ensure that no errors are reported. This is intended to catch regressions in ESLint that are missed by ESLint's unit tests.
Usage
$ npm install eslint-canary -g
$ eslint-canary path/to/package/folder/containing/eslint
Development
$ git clone https://github.com/eslint/eslint-canary
$ cd eslint-canary
$ npm install
$ npm test
