Instructions for Cypress and TypeScript

In the root level of your testing folder, install the @axe-core/watcher package and all of its dependencies using npm or your preferred package manager (for example, Yarn or pnpm).

npm install --save-dev @axe-core/watcher

In cypress.config.ts, import the cypressConfig function from the @axe-core/watcher package and wrap your config with it:

import { defineConfig } from 'cypress';
import { cypressConfig } from '@axe-core/watcher';

const API_KEY = process.env.API_KEY

export default defineConfig(
  cypressConfig({
    axe: {
      apiKey: API_KEY
    },
    // Your existing Cypress configuration code here
  })
);

In your Cypress support file (commonly called cypress/support/e2e.ts), import the @axe-core/watcher package cypressCommands and call axeWatcherFlush() after each test:

import '@axe-core/watcher/dist/cypressCommands';

afterEach(() => {
  cy.axeWatcherFlush();
});

You're all done. Run your end-to-end tests and check your results. Please note @axe-core/watcher only runs in Chrome and should only be used in Cypress run mode. It may be used with --headless=new or --headed (for example, cypress run --headed --browser=chrome).
