Locale, Timezone & Geolocation

Emulate user locale, timezone, geolocation, permissions, and color scheme

typescript
import { defineConfig } from '@playwright/test';

export default defineConfig({
  use: {
    locale: 'de-DE',
    timezoneId: 'Europe/Berlin',
    colorScheme: 'dark',
    geolocation: { latitude: 52.52, longitude: 13.405 },
    permissions: ['geolocation'],
  },
});
💡 test.use() overrides config-level settings for all tests in the current file
⚡ emulateMedia() lets you switch color scheme mid-test without reloading
📌 permissions must be granted explicitly — geolocation, notifications, clipboard, etc.
🟢 Locale affects Intl APIs, date formatting, and number display in the browser context
