# Salesforce Accessibility Automation Libraries
Automated Accessibility Testing Libraries and Tools ([@sa11y packages](https://www.npmjs.com/org/sa11y)) based on [axe-core][axe] providing support for [Jest](#jest-integration) unit tests, [WebdriverIO](#wdio-integration) component/integration tests used by teams in Salesforce. However, they are not specific to Salesforce and can be used to test any UI [supported by axe-core](https://github.com/dequelabs/axe-core#supported-browsers) for accessibility. These libraries are designed to be flexible, customizable and reusable to support automated accessibility testing in different testing workflows from unit to integration tests.

This repo contains the following packages for automated accessibility testing:
### [Jest integration](./packages/jest/README.md)
[![published npm version of @sa11y/jest](https://img.shields.io/npm/v/@sa11y/jest)](https://www.npmjs.com/package/@sa11y/jest)
![node-current (scoped)](https://img.shields.io/node/v/@sa11y/jest)- Provides a `toBeAccessible()` accessibility matcher for Jest
- integrates the [assertAccessible API](./packages/assert/README.md) with the [Jest assertion API](https://jestjs.io/docs/en/using-matchers)
- Provides an option to set up the sa11y API to be invoked automatically at the end of each test
- To add accessibility testing to your Jest tests use this package![Screenshot showing Sa11y Jest API usage and a11y errors showing up in VSCode](https://github.com/salesforce/sa11y/blob/media/screenshot/jest.png?raw=true)
### [WDIO integration](./packages/wdio/README.md)
[![published npm version of @sa11y/wdio](https://img.shields.io/npm/v/@sa11y/wdio)](https://www.npmjs.com/package/@sa11y/wdio)
![node-current (scoped)](https://img.shields.io/node/v/@sa11y/wdio)- Provides `assertAccessible()`, `assertAccessibleSync()` APIs that can be used with [WebdriverIO](https://webdriver.io/) to check accessibility of web pages rendered in browsers
![Screenshot showing a11y errors from a test using Sa11y WDIO in a terminal](https://github.com/salesforce/sa11y/blob/media/screenshot/wdio.png?raw=true)
### [assertAccessible API](./packages/assert/README.md)
[![published npm version of @sa11y/assert](https://img.shields.io/npm/v/@sa11y/assert)](https://www.npmjs.com/package/@sa11y/assert)
![node-current (scoped)](https://img.shields.io/node/v/@sa11y/assert)- Checks DOM or HTML Element for accessibility issues and throws an error if a11y issues are found
- To add accessibility testing to your Javascript unit tests _not_ using Jest, use this package### [a11y results formatter](./packages/format/README.md)
[![published npm version of @sa11y/format](https://img.shields.io/npm/v/@sa11y/format)](https://www.npmjs.com/package/@sa11y/format)
![node-current (scoped)](https://img.shields.io/node/v/@sa11y/format)- Formats raw JSON output of a11y issues from [axe] into an easy to consume format by consolidating and cross-referencing
- Used by assert Accessible API and Jest a11y matcher
- To use axe directly and want to format the results from `axe.run` use this package
- A new formatter `groupViolationResultsProcessor` also made available to group the a11y violations per jest test case as the existing formatter would generate test failures for each violation### [Preset accessibility rules](./packages/preset-rules/README.md)
[![published npm version of @sa11y/preset-rules](https://img.shields.io/npm/v/@sa11y/preset-rules)](https://www.npmjs.com/package/@sa11y/preset-rules)
![node-current (scoped)](https://img.shields.io/node/v/@sa11y/preset-rules)- Provides Base, Extended, Full accessibility preset rules as [axe] configuration
- The Base preset rule is used by default in the Jest a11y matcher and assert Accessible APIs
- The APIs can be overridden to use the Extended or Full ruleset as necessary### [Minified bundle for testing in browser](./packages/browser-lib/README.md)
[![published npm version of @sa11y/browser-lib](https://img.shields.io/npm/v/@sa11y/browser-lib)](https://www.npmjs.com/package/@sa11y/browser-lib)
![node-current (scoped)](https://img.shields.io/node/v/@sa11y/browser-lib)- Provides a minified version of selected `@sa11y` libraries to be injected into a browser (using webdriver) and executed from integration testing workflows.
- Gives WCAG SC for rulesets in addition with [axe] tags### Internal packages
