Network & API Testing — quiz

You want to test the empty-state UI when /api/products returns []. What's the right Playwright Python tool?

• Modify the backend so it returns [] in test mode
• page.route('**/api/products', lambda route: route.fulfill(json=[])) — the Python API uses snake_case (route.fulfill, not routeFulfill), accepts a callable handler that receives the Route, and lets you return synthetic responses without backend changes
• Use unittest.mock.patch on requests.get
• page.route exists only in JS/TS
