01

How do you reduce the execution time of a 2000-test suite?

Save to ▾
Show answer
Run in parallel with sharding, reuse authentication state, set up data through APIs, avoid unnecessary waits, run smoke on every commit and the full suite nightly.
02

How do you handle iframes in Playwright?

RazorpayMedium
Save to ▾
Show answer
Use page.frameLocator('#frame').getByRole(...) so actions work inside the iframe with auto-waiting.
03

How do you manage test data and environments?

RazorpayMedium
Save to ▾
Show answer
Use environment variables or .env files, a baseURL in config, API calls for setup and cleanup, and unique data per run.
04

How do you handle a new tab?

Save to ▾
Show answer
const [newPage] = await Promise.all([ context.waitForEvent('page'), page.getByText('Open').click(), ]); await newPage.waitForLoadState();
05

How do you handle errors in async code?

Save to ▾
Show answer
Use try-catch with await, or .catch() on promises, and make sure rejected promises are never left unhandled.
06

Explain the event loop.

RazorpayMedium
Save to ▾
Show answer
JavaScript runs one call stack and uses queues for async work; the event loop pushes callbacks from the microtask (promises) and task queues when the stack is empty.
07

How do you shard tests across machines?

RazorpayMedium
Save to ▾
Show answer
Use npx playwright test --shard=1/4 in each CI job and merge reports afterwards to reduce total run time.
08

How do you handle shadow DOM?

RazorpayMedium
Save to ▾
Show answer
Playwright locators pierce open shadow roots by default, so getByRole and CSS locators work without special handling.
09

How do you handle file uploads and downloads?

RazorpayMedium
Save to ▾
Show answer
setInputFiles on the input for uploads; for downloads wait on page.waitForEvent('download') and save or inspect the file.
10

What are higher-order functions?

RazorpayMedium
Save to ▾
Show answer
Functions that take other functions as arguments or return them, such as map, filter and reduce, or a helper that wraps retry logic around a test step.
11

How do you run tests in parallel and control workers?

RazorpayMedium
Save to ▾
Show answer
Files run in parallel by default; set workers in the config and use test.describe.configure({ mode: 'parallel' }) for tests inside a file.
12

How do you mock network requests?

RazorpayMedium
Save to ▾
Show answer
page.route('**/api/items', route => route.fulfill({ json: [...] })) intercepts and replies with test data; route.abort() simulates failures.
13

Design a Playwright framework for a 500-test suite.

Save to ▾
Show answer
TypeScript + POM + custom fixtures, environment configs, API helpers for test data, tags like @smoke, sharding across CI machines, retries with traces, HTML/Allure reports, lint and review rules.
14

How would you structure a large Playwright framework for a team?

Save to ▾
Show answer
Separate tests, page objects, fixtures, utilities, test data and config; use tags, projects, shared auth setup, linting, code review and a CI pipeline with sharding and reports.
15

What is hoisting?

RazorpayMedium
Save to ▾
Show answer
Declarations of var and functions are moved to the top of their scope at compile time; let and const are hoisted but stay in the temporal dead zone until declared.
16

What is async/await?

Save to ▾
Show answer
Syntax over Promises: an async function returns a Promise and await pauses until it resolves. Every Playwright action returns a Promise, so you await each step.
17

What are fixtures and how do you create a custom one?

RazorpayMedium
Save to ▾
Show answer
Fixtures set up and tear down test dependencies. Extend with test.extend({ loggedInPage: async ({ page }, use) => { ...; await use(page); } }).
18

What happens if you forget an await?

RazorpayMedium
Save to ▾
Show answer
The action runs without waiting, so the next step may run first — causing flaky failures or 'Target closed' errors. The @typescript-eslint/no-floating-promises rule catches it.
19

How do you run Playwright in GitHub Actions?

RazorpayMedium
Save to ▾
Show answer
Workflow: checkout → setup-node → npm ci → npx playwright install --with-deps → npx playwright test → upload playwright-report as an artifact.
20

What are soft assertions?

RazorpayMedium
Save to ▾
Show answer
await expect.soft(locator).toHaveText('...') records the failure but lets the test continue, so you see every mismatch in one run.
21

How do you measure API response time?

RazorpayMedium
Save to ▾
Show answer
Record timestamps around the request or use response timing, then assert the duration is under an agreed threshold.
22

How do you integrate Playwright with Allure or other reports?

RazorpayMedium
Save to ▾
Show answer
Install the allure-playwright reporter, add it in the config reporters array and generate the report from the allure-results folder in CI.
23

How do you validate JSON schema?

RazorpayMedium
Save to ▾
Show answer
Use a library such as zod or ajv to define the expected schema and parse the response to fail on missing or wrongly typed fields.
24

How would you type the response of an API call in TypeScript?

Save to ▾
Show answer
Define an interface for the payload, cast or validate the parsed JSON to it (for example with zod), and use that type in assertions to catch shape changes.
25

How do you handle multiple tabs or pop-ups?

RazorpayMedium
Save to ▾
Show answer
Wait for the popup event with const [popup] = await Promise.all([page.waitForEvent('popup'), page.click('a')]), then interact with popup.
26

What is the difference between map, filter and reduce?

RazorpayMedium
Save to ▾
Show answer
map transforms each item, filter keeps items that match a condition, and reduce combines all items into a single value.
27

Write an API test with the request fixture.

RazorpayMedium
Save to ▾
Show answer
test('get user', async ({ request }) => { const res = await request.get('/api/users/1'); expect(res.ok()).toBeTruthy(); expect((await res.json()).id).toBe(1); });
28

What reporters does Playwright provide?

RazorpayMedium
Save to ▾
Show answer
List, dot, line, HTML, JSON and JUnit reporters, plus integrations such as Allure, configurable per environment.
29

What is the difference between synchronous and asynchronous code?

RazorpayMedium
Save to ▾
Show answer
Synchronous code runs line by line and blocks; asynchronous code starts a task and continues, handling the result later with promises or await.
30

What is the difference between beforeEach and fixtures?

RazorpayMedium
Save to ▾
Show answer
beforeEach runs the same code before every test in scope; fixtures are lazy, composable and only set up what a test uses.
31

What is the difference between API testing and UI testing?

Save to ▾
Show answer
API testing checks services directly and is fast and stable; UI testing checks the full user experience in the browser and is slower.
32

How do you share cookies between API login and UI?

RazorpayMedium
Save to ▾
Show answer
Log in with request.post, call request.storageState(), and create a browser context using that state.
33

How do you mock an API response?

RazorpayMedium
Save to ▾
Show answer
await page.route('**/api/users', route => route.fulfill({ status: 200, json: [{ id: 1, name: 'Test' }] }) );
34

How do you take screenshots and videos?

RazorpayMedium
Save to ▾
Show answer
page.screenshot() for captures and config options use: { screenshot: 'only-on-failure', video: 'retain-on-failure' } for automatic evidence.
35

What is destructuring and the spread operator?

RazorpayMedium
Save to ▾
Show answer
Destructuring pulls values from arrays or objects into variables; spread expands an array or object into another, useful for copying and merging config.
36

What is the difference between click and dispatchEvent?

RazorpayMedium
Save to ▾
Show answer
click simulates a real user click with actionability checks; dispatchEvent fires a DOM event directly without those checks.
37

How do retries work?

RazorpayMedium
Save to ▾
Show answer
Set retries in the config or CLI and failed tests re-run in a fresh context, with trace recorded on first retry to diagnose flakiness.
38

How do you tag and filter tests?

RazorpayMedium
Save to ▾
Show answer
Add tags in the title (@smoke) or use the tag option, and run with --grep @smoke or --grep-invert.
39

How would you handle a very flaky element that appears after an animation?

Save to ▾
Show answer
Rely on auto-waiting plus a web-first assertion on the final state, disable animations in config for tests and avoid fixed timeouts.
40

Locator vs ElementHandle?

Save to ▾
Show answer
A Locator is lazy, re-resolved on every action and auto-waits (recommended). An ElementHandle points to one DOM node and can go stale.
41

How do you reuse login state across tests?

RazorpayMedium
Save to ▾
Show answer
Log in once in global setup, save storageState to a JSON file and set use.storageState in the config so every test starts logged in.
42

What are global setup and teardown?

RazorpayMedium
Save to ▾
Show answer
Scripts that run once before or after the whole run, for seeding data, starting services or creating authentication state.
43

interface vs type in TypeScript?

RazorpayMedium
Save to ▾
Show answer
Both describe object shapes. Interfaces can be extended and merged; type aliases can also describe unions and primitives. Use interfaces for page or test-data shapes, types for unions.
44

How do you create test data through the API before a UI test?

Save to ▾
Show answer
In a fixture or beforeEach, call the API (request.post) to create the user or order, use it in the UI test, then delete it in teardown. It is faster and more reliable than creating data through the UI.
45

What is the difference between page, context and browser?

RazorpayMedium
Save to ▾
Show answer
A browser is the engine instance; a context is an isolated session (cookies, storage); a page is a tab inside a context.
46

How do you write a Page Object in Playwright?

Save to ▾
Show answer
A class receives page in its constructor, stores locators as properties and exposes actions like login(user, pass). Tests call page objects, not raw locators.
47

How do you test file downloads and verify their content?

RazorpayMedium
Save to ▾
Show answer
Capture the download event, save it with download.saveAs, then read the file in Node and assert on name, size or content.
48

How do you test accessibility with Playwright?

RazorpayMedium
Save to ▾
Show answer
Integrate axe-core through @axe-core/playwright, run an analysis on the page and assert that there are no violations.
49

How do you set test timeouts?

RazorpayMedium
Save to ▾
Show answer
Use timeout and expect.timeout in config, test.setTimeout() for one test and test.slow() for known slower tests.
50

What is APIRequestContext?

RazorpayMedium
Save to ▾
Show answer
The object behind the request fixture that holds base URL, headers and cookies, and can share cookies with a browser context.
51

What is the difference between null and undefined?

RazorpayMedium
Save to ▾
Show answer
undefined means a variable has not been assigned; null is an intentional empty value.
52

How do you handle authentication to avoid logging in every test?

RazorpayMedium
Save to ▾
Show answer
Log in once in a setup project, save storageState to a file and reuse it in other projects or tests.
53

How do you install and start a Playwright project?

Save to ▾
Show answer
Run npm init playwright@latest, which sets up config, example tests and browsers; execute with npx playwright test.
54

Tests are flaky in CI. How do you debug them?

Save to ▾
Show answer
Turn on trace: 'on-first-retry', open the trace viewer, check network and timing, replace hard waits with web-first assertions, isolate test data and check for sharding conflicts.
55

What are arrow functions?

Save to ▾
Show answer
A short function syntax that does not have its own this and arguments, taking them from the surrounding scope.
56

What is npm and package.json?

Save to ▾
Show answer
npm is the Node package manager. package.json lists the project's dependencies and scripts, such as the command that runs the tests.
57

How do you send a POST request with a JSON body?

RazorpayMedium
Save to ▾
Show answer
await request.post('/api/users', { data: { name: 'Asha' } }) automatically sets JSON headers and serialises the payload.
58

How do you use test.step and test annotations?

RazorpayMedium
Save to ▾
Show answer
test.step groups actions into named steps in reports; annotations such as test.skip, test.fixme and test.slow communicate intent and adjust behaviour.
59

How do you run only smoke tests?

Save to ▾
Show answer
Tag tests (in the title or with { tag: '@smoke' }) and run: npx playwright test --grep @smoke (use --grep-invert to exclude).
60

How do you test a file download?

RazorpayMedium
Save to ▾
Show answer
const [download] = await Promise.all([ page.waitForEvent('download'), page.getByText('Export').click(), ]); await download.saveAs('reports/file.csv');
61

What is auto-waiting in Playwright?

Save to ▾
Show answer
Before acting, Playwright waits for the element to be attached, visible, stable, enabled and able to receive events — so manual waits are rarely needed.
62

What are generics in TypeScript?

RazorpayMedium
Save to ▾
Show answer
Placeholders for types that make reusable code type-safe, for example a helper function returning the same type of item that it receives.
63

How do you validate an API response in Playwright?

RazorpayMedium
Save to ▾
Show answer
Assert the status with expect(res.status()).toBe(200), parse res.json() and check fields, using schema validation for the structure.
64

How do you work with iframes?

Save to ▾
Show answer
const frame = page.frameLocator('#payment-frame'); await frame.getByLabel('Card number').fill('4111 1111 1111 1111');
65

let vs const vs var?

Save to ▾
Show answer
var is function-scoped and hoisted. let and const are block-scoped; const can't be reassigned (though an object it points to can change). Prefer const, then let.
66

How do you combine API and UI tests?

RazorpayMedium
Save to ▾
Show answer
Create test data through API calls, verify it in the UI and clean up via API, which makes UI tests faster and more reliable.
67

How do you run tests in Docker?

RazorpayMedium
Save to ▾
Show answer
Use the official Playwright image which contains browsers and dependencies, mount the project and run npx playwright test for consistent CI environments.
68

How do you structure environment-specific configs in Playwright?

RazorpayMedium
Save to ▾
Show answer
Use dotenv files per environment, read them in playwright.config and set baseURL and credentials from variables, selecting with an ENV flag.
69

How would you design API test coverage for a new endpoint?

Save to ▾
Show answer
Cover happy path, validation errors, auth and permissions, boundary values, idempotency, schema, performance and data cleanup.
70

How do you test file upload via API?

RazorpayMedium
Save to ▾
Show answer
Use request.post with multipart: { file: { name, mimeType, buffer } } and assert the response and stored file details.
71

How does Playwright's trace viewer help?

RazorpayMedium
Save to ▾
Show answer
It records screenshots, DOM snapshots, network calls and actions per step so you can replay a failed run and see exactly what happened.
72

What is a locator in Playwright?

Save to ▾
Show answer
An object describing how to find an element, re-evaluated on every action so it always targets the current DOM.
73

What is the difference between TypeScript and JavaScript?

Save to ▾
Show answer
TypeScript adds static types on top of JavaScript and compiles to it. Types catch errors early and give better autocomplete, which helps in larger test suites.
74

How do you mock third-party APIs in UI tests?

RazorpayMedium
Save to ▾
Show answer
Use page.route to intercept the call and fulfil it with fixed JSON so tests do not depend on external systems.
75

Which locators does Playwright recommend?

RazorpayMedium
Save to ▾
Show answer
User-facing ones: getByRole, getByText, getByLabel, getByPlaceholder and getByTestId, which are more resilient than CSS or XPath.
76

How do you test geolocation, permissions and time zones?

RazorpayMedium
Save to ▾
Show answer
Set them in the context options (geolocation, permissions, timezoneId, locale) to simulate users from other regions.
77

How does Playwright compare with Selenium and Cypress?

RazorpayMedium
Save to ▾
Show answer
Playwright supports multiple browsers, tabs, languages and has auto-waiting and tracing; Selenium has the widest ecosystem; Cypress runs in-browser with a great UI but has more limits across tabs.
78

How do you test pagination or chained API calls?

RazorpayMedium
Save to ▾
Show answer
Read the next page link or IDs from earlier responses, loop until done and assert counts and uniqueness; pass IDs between calls in the same test.
79

How do you wait for a network response in Playwright?

RazorpayMedium
Save to ▾
Show answer
Use page.waitForResponse(res => res.url().includes('/api/orders') && res.ok()) together with the action that triggers it.
