  4. Write a program to read test data from a JSON file and filter the cases to run.
Part 9. Framework Patterns3 programs
  1. Write a custom fixture that gives every test a logged-in dashboard page object.
  2. Write a typed config loader that reads environment variables with safe defaults.
  3. Write a test data builder using the builder pattern.

Playwright TypeScript Last-Minute Notes12 parts, 48 questions

Part 1. Playwright Basics and Architecture4 questions
  1. Your company runs Selenium. Why are teams like yours moving to Playwright?
  2. One test must show an admin and a customer working at the same time. How do Browser, BrowserContext and Page make that possible?
  3. Which browsers does Playwright support, and what is the difference between bundled Chromium and the Chrome channel?
  4. How do you set up a Playwright TypeScript project from scratch?
Part 2. TypeScript for Testers5 questions
  1. Why use TypeScript instead of JavaScript for Playwright tests?
  2. What are interfaces and types, and where do you use them in a test framework?
  3. A test sometimes fails with "Target closed" and sometimes passes. You suspect a missing await. Explain what is going on.
  4. What are generics, and how do they help in a test framework?
  5. How do you manage environment config and secrets in a Playwright TypeScript framework?
Part 3. Locators5 questions
  1. Your element handle throws errors after the page re-renders. Why do Playwright locators not have this problem?
  2. Which locator strategy do you recommend, and in what order?
  3. How do you work with lists and tables using filter, nth and chaining?
  4. A card payment form sits inside an iframe and a cookie banner lives in shadow DOM. How do you automate both?
  5. How do you generate and debug locators quickly?
Part 4. Auto-waiting and Assertions5 questions
  1. What is auto-waiting, and what does Playwright check before it performs an action?
  2. What are web-first assertions, and why are they better than reading a value and checking it?
  3. Explain soft assertions, expect.poll and toPass.
  4. What are the different timeouts in Playwright, and what are their defaults?
  5. How do you do visual testing with toHaveScreenshot?
Part 5. Test Runner, Config and Projects4 questions
  1. Walk me through the important settings in playwright.config.ts.

  4. How do you run tests in order when a flow truly needs it?
Part 6. Fixtures and Hooks3 questions
  1. Every spec file starts with the same 20 lines of setup. How do Playwright fixtures fix this?
  2. What is the difference between test-scoped and worker-scoped fixtures? What is an auto fixture?
  3. When do you use beforeAll and beforeEach hooks instead of fixtures?
Part 7. Page Object Model and Framework Design3 questions
  1. The same login locators are copied into 30 test files. How would you refactor this with the Page Object Model?
  2. How would you design a scalable Playwright framework? Walk me through the folder structure.
  3. Two parallel tests keep editing the same student account and fail at random. How should test data be managed?
Part 8. Network Mocking and API Testing5 questions
  1. How do you mock or change network responses with page.route?
  2. After clicking Place order, you need the order id from the API response. How do you capture it reliably?

  2. Your suite takes 40 minutes on one machine. How do you split it across 4 CI machines and still get one report?
  3. Your team wants every pull request tested automatically. What does a Playwright pipeline look like?
  4. Screenshots differ between your laptop and CI because fonts render differently. How does running Playwright in Docker fix this?

  3. What are Playwright test agents (planner, generator, healer)?

A real page from the playbook

Write a Playwright program to verify a table column is sorted after clicking its header.

  • Click the column header.
  • Read every cell of that column with allTextContents.
  • Convert the texts to numbers if needed.
  • Compare with a sorted copy of the same list.
await page.getByRole('columnheader', { name: 'Price' }).click();
const cells = page.locator('table tbody tr td:nth-child(3)');
const prices = (await cells.allTextContents())
  .map(t => Number(t.replace(/[^0-9.]/g, '')));
const sorted = [...prices].sort((a, b) => a - b);
expect(prices).toEqual(sorted);

Remember: Copy before sorting ([...prices]) so you compare against the original order.

Common mistake: Calling prices.sort() directly. It sorts the original array, so the check always passes.
