Essential Concepts

Browser -> Context -> Page Hierarchy

Browser (chromium/firefox/webkit)
  └── Context (isolated session: cookies, storage)
        └── Page (single tab/window)

• Browser: The browser process (Chrome, Firefox, or WebKit)
• Context: Isolated browser session with its own cookies, localStorage, and cache
• Page: A single tab or popup window within a context

New Browser    chromium    headless=false
New Context    viewport={'width': 1920, 'height': 1080}
New Page       https://example.com

Auto-Waiting

Browser Library automatically waits for elements to be actionable before interacting. No explicit waits needed in most cases.

• Waits for element to be visible
• Waits for element to be stable (not animating)
• Waits for element to be enabled
• Waits for element to receive events
