# Contributing to esformatter-semicolon-first Please add test cases to the `test/compare/input.js` and `test/compore/output.js`. That will reduce the chance of introducing regressions and make it clear what is the expected behavior. Install the npm dependencies: ``` $ cd esformatter-semicolon-first $ npm install ``` And to run it you just need to do: ``` $ npm test ``` It will compare the `input.js` with the `output.js`. Thanks!
