Implementation

test('Ionic app navigation works correctly', async ({ page }) => {
  await page.goto('/');
  // Ionic uses shadow DOM for components
  const tabBar = page.locator('ion-tab-bar');
  await expect(tabBar).toBeVisible();
  await tabBar.locator('ion-tab-button[tab="profile"]').click();
  await expect(page.locator('ion-title')).toContainText('Profile');
});

Run Tests

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

Frequently Asked Questions

How to interact with Ionic components in Playwright?

Use page.locator('ion-button') for standard queries. Use >> to pierce shadow DOM for nested elements.

How to test Ionic modal popups?

Trigger the modal, then use page.locator('ion-modal') to interact with the modal content.

Can Playwright test Ionic alerts and action sheets?

Yes, click the trigger button and verify ion-alert or ion-action-sheet components appear.

How to test Ionic form validation?

Fill Ionic input components and verify ion-note elements show validation error messages.

How to test swipe-to-delete on Ionic lists?

Simulate swipe gesture using mouse events on the ion-item-sliding component.
