Basic Playwright TypeScript Interview Questions

1. What is Playwright?

Answer:

Playwright is an open-source browser automation framework developed by Microsoft. It supports Chromium, Firefox, and WebKit, making it suitable for cross-browser web automation.

2. Why use TypeScript with Playwright?

Answer:

TypeScript provides:

  • Static type checking
  • Better IntelliSense
  • Early error detection
  • Easier maintenance
  • Improved readability

These advantages are especially useful for enterprise automation frameworks.

3. How do you install Playwright?

npm init playwright@latest

This command creates a Playwright project, installs dependencies, and downloads supported browsers.

4. Which browsers does Playwright support?

  • Chromium
  • Firefox
  • WebKit

5. What is auto-waiting?

Model Answer:

Playwright automatically waits for elements to become visible, stable, enabled, and ready before interacting with them. This reduces flaky tests and removes many explicit waits.

Intermediate Interview Questions

6. What are Playwright locators?

Locators identify page elements for interaction.

Preferred order:

  1. getByRole()
  2. getByLabel()
  3. getByPlaceholder()
  4. getByText()
  5. getByTestId()
  6. locator()

7. What are assertions?

Assertions verify that the application behaves as expected.

import { test, expect } from ‘@playwright/test’;

test(‘Dashboard verification’, async ({ page }) => {

  await page.goto(‘https://example.com/dashboard’);

  await expect(page).toHaveURL(/dashboard/);

  await expect(

    page.getByRole(‘heading’, {

      name: ‘Dashboard’

    })

  ).toBeVisible();

});

Explanation

This example verifies:

  • Correct page navigation
  • Dashboard heading visibility

8. What are fixtures?

Fixtures provide reusable setup and teardown logic, such as browser pages, authenticated sessions, or test data, helping keep tests clean and consistent.

9. What is Trace Viewer?

Trace Viewer records:

  • Screenshots
  • DOM snapshots
  • Network requests
  • Console logs
  • Timeline of actions

It helps diagnose failures without rerunning tests.

10. What is the Page Object Model?

The Page Object Model (POM) organizes page interactions into reusable classes, improving maintainability and reducing duplicated code.

Advanced and Scenario-Based Interview Questions

11. How would you reduce flaky tests?

Model Answer

  • Use semantic locators.
  • Rely on auto-waiting.
  • Avoid fixed delays.
  • Keep tests independent.
  • Review Trace Viewer for failures.
  • Use retries to diagnose issues, not to hide them.

12. How would you test a multi-step checkout process?

Suggested Approach

  1. Log in.
  2. Search for a product.
  3. Add it to the cart.
  4. Complete checkout.
  5. Verify the confirmation page.
  6. Validate the order using an API if available.

13. Your test passes locally but fails in CI. What would you do?

Model Answer

  • Review pipeline logs.
  • Compare browser versions.
  • Inspect screenshots and traces.
  • Check environment variables.
  • Verify network stability.
  • Confirm test data availability.

14. How would you organize a large automation framework?

Suggested Answer

Use separate folders for:

  • Page Objects
  • Tests
  • Utilities
  • Fixtures
  • API helpers
  • Test data
  • Reports
  • Configuration

This improves maintainability and scalability.

  await page.goto(‘https://example.com/login’);

  await page.getByLabel(‘Username’)

    .fill(‘admin’);

  await page.getByLabel(‘Password’)

    .fill(‘password’);

  await page.getByRole(‘button’, {

    name: ‘Login’

  }).click();

  await expect(page)

    .toHaveURL(/dashboard/);

});

How to Explain This in an Interview
