Network Mocking & API Testing — quiz

You want to test the empty-state UI when the products API returns `[]`. Which Playwright API is the right tool?

• page.evaluate(() => fetch('/products').then(r => r.json()))
• await page.route('**/api/products', route => route.fulfill({ json: [] })) — intercepts the request and returns a mocked response
• Use a sinon stub on window.fetch
• Modify the backend to return `[]` in the test environment
