Accessibility testing utils

Installation

yarn add accessibility-testing-utils
OR
npm install accessibility-testing-utils

1. Blur the site to test tab navigation and accessibility role/label/state.

• This will disable pointer events, forcing you to use tabs so you can test the labels, state, values etc with a VoiceOver just like a real person.
• Credits http://udacity.github.io/ud891/lesson3-semantics-built-in/03-experience-screen-reader/

Usage

import {blurElementStyle} from "accessibility-testing-utils"

<div style={blurElementStyle}>{children}</div>

2. Testing alt attribute in images.

• This will make src of all the images an invalid string.
• Even though tools like Lighthouse makes sure image has a valid alt attribute, but it's better to test it manually.
• Watch this to know why this is important.

Usage

import { testImageAltAttribute } from 'accessibility-testing-utils';

 React.useEffect(()=>{
    testImageAltAttribute()
  },[])
