feat(api): add explicit async testInfo.attach We add an explicit async API for attaching file paths (and Buffers) to tests that can be awaited to help users ensure they are attaching files that actually exist at both the time of the invocation and later when reporters (like the HTML Reporter) run and package up test artifacts. This is intended to help surface attachment issues as soon as possible so you aren't silently left with a missing attachment minutes/days/months later when you go to debug a suddenly breaking test expecting an attachment to be there. NB: The current implemntation incurs an extra file copy compared to manipulating the raw attachments array. If users encounter performance issues because of this, we can consider an option parameter that uses rename under the hood instead of copy. However, that would need to be used with care if the file were to be accessed later in the test.
🎭 Playwright
Documentation | API reference
Playwright is a Node.js library to automate Chromium, Firefox and WebKit with a single API. Playwright is built to enable cross-browser web automation that is ever-green, capable, reliable and fast.
| Linux | macOS | Windows | |
|---|---|---|---|
| Chromium 98.0.4722.0 | ✅ | ✅ | ✅ |
| WebKit 15.4 | ✅ | ✅ | ✅ |
| Firefox 94.0.1 | ✅ | ✅ | ✅ |
Headless execution is supported for all the browsers on all platforms. Check out system requirements for details.
Usage
npm i -D playwright
This installs Playwright and browser binaries for Chromium, Firefox and WebKit. Once installed, you can require Playwright in a Node.js script and automate web browser interactions.
Capabilities
Playwright is built to automate the broad and growing set of web browser capabilities used by Single Page Apps and Progressive Web Apps.
- Scenarios that span multiple page, domains and iframes
- Auto-wait for elements to be ready before executing actions (like click, fill)
- Intercept network activity for stubbing and mocking network requests
- Emulate mobile devices, geolocation, permissions
- Support for web components via shadow-piercing selectors
- Native input events for mouse and keyboard
- Upload and download files
Examples
Page screenshot
This code snippet navigates to whatsmyuseragent.org in Chromium, Firefox and WebKit, and saves 3 screenshots.
const playwright = require('playwright');
(async () => {
for (const browserType of [playwright.chromium, playwright.firefox, playwright.webkit]) {
const browser = await browserType.launch();
const context = await browser.newContext();
const page = await context.newPage();
await page.goto('http://whatsmyuseragent.org/');
await page.screenshot({ path: `example-${browserType.name()}.png` });
await browser.close();
}
})();
Mobile and geolocation
This snippet emulates Mobile Safari on a device at a given geolocation, navigates to maps.google.com, performs action and takes a screenshot.
const { webkit, devices } = require('playwright');
const iPhone11 = devices['iPhone 11 Pro'];
(async () => {
const browser = await webkit.launch();
const context = await browser.newContext({
...iPhone11,
locale: 'en-US',
geolocation: { longitude: 12.492507, latitude: 41.889938 },
permissions: ['geolocation']
});
const page = await context.newPage();
await page.goto('https://maps.google.com');
await page.click('text="Your location"');
await page.waitForRequest(/.*preview\/pwa/);
await page.screenshot({ path: 'colosseum-iphone.png' });
await browser.close();
})();
Evaluate in browser context
This code snippet navigates to example.com in Firefox, and executes a script in the page context.
const { firefox } = require('playwright');
(async () => {
const browser = await firefox.launch();
const context = await browser.newContext();
const page = await context.newPage();
await page.goto('https://www.example.com/');
const dimensions = await page.evaluate(() => {
return {
width: document.documentElement.clientWidth,
height: document.documentElement.clientHeight,
deviceScaleFactor: window.devicePixelRatio
}
});
console.log(dimensions);
await browser.close();
})();
Intercept network requests
This code snippet sets up request routing for a WebKit page to log all network requests.
const { webkit } = require('playwright');
(async () => {
const browser = await webkit.launch();
const context = await browser.newContext();
const page = await context.newPage();
// Log and continue all network requests
await page.route('**', route => {
console.log(route.request().url());
route.continue();
});
await page.goto('http://todomvc.com');
await browser.close();
})();
