Instructions for Playwright and TypeScript
Configuring your tests with Playwright 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 your test file or files, import the playwrightConfig() function, the wrapPlaywright() function, and the PlaywrightController class from @axe-core/watcher:
import { wrapPlaywrightPage, playwrightConfig, PlaywrightController } from '@axe-core/watcher';
-
In your test setup code (typically in a before or beforeAll block), wrap any existing code for creating a browserContext instance with a call to playwrightConfig while providing your API key:
import { chromium, BrowserContext } from 'playwright'; import { playwrightConfig } from '@axe-core/watcher'; const API_KEY = process.env.API_KEY const browserContext: BrowserContext = await chromium.launchPersistentContext( /** * We set userDataDir to an empty string which saves * browser data to a temporary directory * @see https://playwright.dev/docs/api/class-browsertype#browser-type-launch-persistent-context */ '', playwrightConfig({ axe: { apiKey: API_KEY }, /** * We support both headless and headed mode with Chrome. * * For headless mode: * - Use '--headless=chrome' for browsers v94-108. * - Use '--headless=new' for browsers v109+. * * For headed mode: * - Remove the '--headless' flag. * * @see https://playwright.dev/docs/chrome-extensions#headless-mode */ headless: false, args: ['--headless=new'] }) );
-
Once you have a page instance, create an instance of the PlaywrightController class and wrap your browserContext:
// Create a page instance, using your browser context. let page = await browserContext.newPage(); // Initialize the PlaywrightController by passing in the Playwright page. const controller = new PlaywrightController(page); // Use the new wrapped Playwright page instance. page = wrapPlaywrightPage(page, controller);
-
Finally, ensure all test results from axe Watcher are flushed out. To do this, add the following block of code to your test teardown code (typically in an afterEach block):
afterEach(async () => { await controller.flush() })
