## 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/**']
});
```
