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

Create a fixtures.js file alongside your existing Playwright Test tests. In this file, import the playwrightTest() function from @axe-core/watcher:

const { playwrightTest } = require('@axe-core/watcher')

const API_KEY = process.env.API_KEY

module.exports = playwrightTest({
  axe: {
    apiKey: API_KEY
  },
  headless: false,
  // Any other Playwright configuration you’d pass to chromium.launchPersistentContext() here
})

In your test files, replace the imports for test and expect from Playwright Test with your fixtures.js file:

const { test, expect } = require('@playwright/test')
// Becomes:
const { test, expect } = require('./fixtures')

You're all done.
