Implementation

test('WebView content loads in hybrid app', async ({ page }) => {
  // Test the web content that loads inside React Native WebView
  await page.goto('/webview-content');
  // WebView typically injects a custom user agent
  const ua = await page.evaluate(() => navigator.userAgent);
  // Test content works for mobile UA
  await expect(page.getByRole('main')).toBeVisible();
  await expect(page.locator('.mobile-only-btn')).toBeVisible();
});

Run Tests

npx playwright test --grep "Playwright Testing for"
npx playwright test --ui

Frequently Asked Questions

How to test React Native WebView content with Playwright?

Test the web URL directly in Playwright while simulating the mobile user agent the WebView uses.

How to mock React Native bridge calls?

Inject window.ReactNativeWebView = { postMessage: jest.fn() } via page.addInitScript().

Can Playwright test Capacitor.js hybrid apps?

Yes, test the web layer directly. Use page.addInitScript to mock Capacitor plugin APIs.

How to test WebView postMessage communication?

Mock window.ReactNativeWebView.postMessage and verify your web code calls it with correct data.

How to test deep link handling in hybrid apps?

Mock the URL scheme handler and verify the correct content loads for deep link URLs.
