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

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

This event is emitted in addition to the
browserContext.on('page') event, but only for popups relevant to this page.
If the action that triggers the popup is unknown, the following pattern can be used.
