# test-exclude The file include/exclude logic used by [nyc](https://github.com/istanbuljs/nyc). [](https://travis-ci.org/istanbuljs/test-exclude) [](https://coveralls.io/github/istanbuljs/test-exclude?branch=master) [](https://github.com/conventional-changelog/standard-version) [](https://greenkeeper.io/) ## Usage ```js const exclude = require('test-exclude'); if (exclude().shouldInstrument('./foo.js')) { // let's instrument this file for test coverage! } ``` _you can load configuration from a key in package.json:_ _package.json_ ```json { "name": "awesome-module", "test": { "include": ["**/index.js"] } } ``` _app.js_ ```js const exclude = require('test-exclude'); if (exclude({ configKey: 'test' }).shouldInstrument('./index.js')) { // let's instrument this file for test coverage! } ``` ## Including node_modules folder by default the `node_modules` folder is added to all groups of exclude rules. In the rare case that you wish to instrument files stored in `node_modules`, a negative glob can be used: ```js const exclude = require('test-exclude'); const e = exclude({ exclude: ['!**/node_modules/**'] }); ``` ## License ISC
