## :man_scientist: Experimental

**:o: ha11y** is a highly experimental package. The API is subject to rapid change.

## Install

```

npm install --save-dev ha11y

```

## Usage

### React

Test:

```js

import React from 'react';

import {shallow} from 'enzyme';

import ha11y from 'ha11y';

import MyImgComp from '../MyImgComp';

it('ha11y test', () => {

    const dom = (

        

            

                Foo

            

            

                {/* Oops... no ALT tag! */}

                

            

        

    );

    const html = shallow(dom).html();

    return ha11y.test(html)

        .then(results => {

            const errors = results.filter(result => result.heading === 'ERROR');

            console.log(errors);

            expect(errors.length).toEqual(0);

        });

});

```

Output:

```shell

  FAIL  src/comps/__tests__/MyImgComp.test.js

  ● Console

```

```json
