Multi-page scenarios

Playwright can automate scenarios that span multiple browser contexts or multiple tabs in a browser window.

Multiple contexts#

Browser contexts are isolated environments on a single browser instance. Playwright can create multiple browser contexts within a single scenario. This is useful when you want to test for multi-user functionality, like chat.

const { chromium } = require('playwright');
// Create a Chromium browser instance
const browser = await chromium.launch();
// Create two isolated browser contexts
const userContext = await browser.newContext();
const adminContext = await browser.newContext();
// Load user and admin cookies
await userContext.addCookies(userCookies);
await adminContext.addCookies(adminCookies);

API reference#

Multiple pages#

Each browser context can host multiple pages (tabs).

  • Each page behaves like a focused, active page. Bringing the page to front is not required.
  • Pages inside a context respect context-level emulation, like viewport sizes, custom network routes or browser locale.
// Create two pages
const pageOne = await context.newPage();
const pageTwo = await context.newPage();
// Get pages of a brower context
const allPages = context.pages();

API reference#

Handling new pages#

The page event on browser contexts can be used to get new pages that are created in the context. This can be used to handle new pages opened by target="_blank" links.

// Get page after a specific action (e.g. clicking a link)
const [newPage] = await Promise.all([
context.waitForEvent('page'),
page.click('a[target="_blank"]') // Opens a new tab
])
await newPage.waitForLoadState();
console.log(await newPage.title());

If the action that triggers the new page is unknown, the following pattern can be used.

// Get all new pages (including popups) in the context
context.on('page', async page => {
await page.waitForLoadState();
await page.title();
})

API reference#

Handling popups#

If the page opens a pop-up, you can get a reference to it by listening to the popup event on the page.

This event is emitted in addition to the browserContext.on('page') event, but only for popups relevant to this page.

// Get popup after a specific action (e.g., click)
const [popup] = await Promise.all([
page.waitForEvent('popup'),
page.click('#open')
]);
await popup.waitForLoadState();
await popup.title();

If the action that triggers the popup is unknown, the following pattern can be used.

// Get all popups when they open
page.on('popup', async popup => {
await popup.waitForLoadState();
await popup.title();
})
