01
interface vs type in TypeScript?
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.

02
What are fixtures and how do you create a custom one?
Show answer
Fixtures set up and tear down test dependencies. Extend with test.extend({ loggedInPage: async ({ page }, use) => { ...; await use(page); } }).
03
Component and end-to-end tests run together and slow down every commit. How do you separate them?
Show answer
Give them separate configs, such as playwright-ct.config.ts with its own testDir for component specs and playwright.config.ts for end-to-end tests, because component tests also need the bundler options and framework test import. In CI, run component tests on every commit as a fast job and end-to-end tests later or in parallel. Shared settings like reporters can live in a common module both configs import.
04
How do you handle date pickers and custom dropdowns?
Show answer
Click to open the control, then use getByRole('option') or a text locator for the target item, instead of relying on fragile index-based selectors.
05
Write a typed helper that retries an async function a few times.
Show answer
async function retry<T>(fn: () => Promise<T>, times = 3): Promise<T> {
let lastError: unknown;
for (let i = 0; i < times; i++) {
try {
return await fn();
} catch (e) {
lastError = e;
}
}
throw lastError;
}
06
How do you handle secrets such as passwords and tokens in CI?
Show answer
Store them in the CI system's secret store and pass them as environment variables, never in the repository or config files. Read them through process.env and fail fast if they are missing. Use dedicated test accounts with limited rights. Avoid printing them in logs, and make sure traces and screenshots do not expose them in reports.
07
How do you assert an element's CSS class, attribute or value?
Show answer
const btn = page.getByRole('button', { name: 'Submit' });
await expect(btn).toHaveClass(/disabled/);
await expect(btn).toHaveAttribute('aria-busy', 'true');
await expect(page.getByLabel('City')).toHaveValue('Pune');
await expect(btn).toHaveCSS('cursor', 'not-allowed');
08
Tell me about a time you reduced pipeline time with parallel runs or sharding.
Show answer
Situation: our regression suite took 55 minutes, so developers skipped it. Task: bring it under 15. Action: I removed shared test data so fullyParallel could be turned on, split the three slowest files, and ran four shards with blob reports merged into one HTML report. Result: the suite finished in 12 minutes and it became a required check on every pull request.
09
What does the failOnStatusCode option do?
Show answer
By default Playwright API calls do not throw on error statuses, you check them yourself. Setting failOnStatusCode: true on a request or context makes it throw for any status other than 2xx or 3xx. It is useful in setup helpers, where any failure should stop the test immediately with a clear message, instead of continuing with bad data.
10
Tell me about a bug you found through API testing that UI tests missed.
Show answer
Situation: the UI hid a delete button for normal users, so UI tests passed. Task: check permissions properly. Action: I called the delete endpoint directly with a normal user's token and it returned 204. Result: the team fixed the server-side permission check, and I added role-based API tests for every admin endpoint.
11
What are arrow functions?
Show answer
A short function syntax that does not have its own this and arguments, taking them from the surrounding scope.
12
What does --repeat-each do?
Show answer
--repeat-each=N runs every selected test N times in the same run, spread across workers. It is useful for checking a new or fixed test for flakiness before merging, for example npx playwright test checkout.spec.ts --repeat-each=20. Combined with several workers it also surfaces tests that collide with each other over shared data.
13
How do you handle iframes in Playwright?
Show answer
Use page.frameLocator('#frame').getByRole(...) so actions work inside the iframe with auto-waiting.
14
How do you share one authenticated API context across all tests in a worker?
Show answer
Create a worker-scoped fixture that calls request.newContext with baseURL and an auth header, or logs in through the API and keeps the cookies. Pass it to use, and dispose it after use returns. Every test in that worker gets the same ready context, so login happens once per worker. Do not store per-test data on it, or tests start depending on each other.
15
Does headless mode behave differently from headed mode?
Show answer
Modern Chromium headless uses the same browser code as headed, so behaviour is very close. Differences still appear in viewport size, GPU rendering, fonts and some OS dialogs. Tests should set an explicit viewport and not depend on window focus. If something passes headed but fails headless, record a trace and compare screenshots.
16
What are global setup and teardown?
Show answer
Scripts that run once before or after the whole run, for seeding data, starting services or creating authentication state.
17
How is toBeVisible different from toBeAttached?
Show answer
toBeAttached only checks that the element exists in the DOM. toBeVisible also needs it to have a non-empty bounding box and no visibility:hidden style. A hidden modal can be attached but not visible. Use toBeVisible for anything a user should see, and toBeAttached for hidden inputs or elements whose presence matters more than appearance.
18
What is the use block in playwright.config?
Show answer
The use block sets default options for every test, such as baseURL, headless, viewport, locale, trace, screenshot and video. Each project can override them in its own use block, and a file can override again with test.use. This layered setup keeps shared settings in one place while still allowing browser- or file-specific changes.
19
What are projects in playwright.config?
Show answer
Named configurations that run the same tests across different browsers, devices or environments.
20
The app polls a status endpoint every few seconds. How do you test the change from Pending to Done?
Show answer
Mock the endpoint with a counter: return Pending for the first two calls and Done after that. Then assert the UI shows Pending and later Done using web-first assertions with a suitable timeout. You can also use page.clock to speed up the polling interval instead of waiting real seconds. This makes a slow real-world process quick and deterministic.
21
Tell me about a disagreement with a developer over a failing test.
Show answer
Situation: a developer said a failing checkout test was flaky and asked to skip it before release. Task: decide based on evidence. Action: I shared the trace showing the total stayed wrong after a coupon was removed and reproduced it manually. Result: we agreed it was a real bug, it was fixed before release, and we started reviewing traces together.
22
How do you take screenshots and videos?
Show answer
page.screenshot() for captures and config options use: { screenshot: 'only-on-failure', video: 'retain-on-failure' } for automatic evidence.
23
How do you return a fake JSON response that depends on the request body?
Show answer
await page.route('**/api/quote', async (route) => {
const body = route.request().postDataJSON();
const price = body.plan === 'pro' ? 999 : 299;
await route.fulfill({
status: 200,
json: { plan: body.plan, price },
});
});
24
Tell me about a time mocking helped you test a hard edge case.
Show answer
Situation: we could not reproduce a bug where the cart broke when the stock API returned zero for one item. Task: cover it with a test. Action: I mocked only the stock endpoint with route.fetch and changed one item's quantity, then asserted the out-of-stock label. Result: the bug was fixed and the test now protects that case on every run.
25
How can you apply extra CSS only while a screenshot is taken?
Show answer
Pass the stylePath option to toHaveScreenshot or set it in the expect.toHaveScreenshot section of the config. The stylesheet is injected just for the capture, so you can hide scrollbars, freeze a carousel, or set visibility hidden on dynamic widgets without changing the app. It is cleaner than adding test-only classes and also works when a mask box would cover too much of the layout.
26
How do you check colour contrast in Playwright tests?
Show answer
Playwright has no built-in contrast assertion, so you run axe-core through @axe-core/playwright, whose color-contrast rule checks text against WCAG ratios such as 4.5 to 1 for normal text. Scan pages in each theme, for example after emulating dark mode with colorScheme. Axe may report some elements as needing review, for example text over images, and those need a manual look.
27
How do you skip a test only in WebKit?
Show answer
test('drag a file onto the upload zone', async ({ page, browserName }) => {
test.skip(browserName === 'webkit', 'Known WebKit drag issue, ticket QA-123');
await page.goto('/upload');
// rest of the test
});
28
How do you run one group of tests serially while the rest of the suite runs in parallel?
Show answer
Put the group in its own project with fullyParallel: false and limit it to one worker, which recent versions allow with a workers setting on the project, or run it in a separate CI step with --project=serial --workers=1. Inside a file, test.describe.configure({ mode: 'serial' }) keeps order. Use project dependencies if the group must run after the parallel tests.
29
What is UI mode and how is it different from --debug?
Show answer
UI mode, opened with npx playwright test --ui, is a dashboard to run, filter and watch tests, with a trace-like timeline for each one and a watch mode that reruns on file changes. --debug opens the Inspector to step through a single run live. Use UI mode for daily development and --debug for stepping through a specific action.
30
How do you handle errors in async code?
Show answer
Use try-catch with await, or .catch() on promises, and make sure rejected promises are never left unhandled.
31
How do you reuse login state across tests?
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.
32
How do you test file downloads and verify their content?
Show answer
Capture the download event, save it with download.saveAs, then read the file in Node and assert on name, size or content.
33
Write a beforeEach hook that opens the home page and accepts the cookie banner.
Show answer
test.beforeEach(async ({ page }) => {
await page.goto('/');
const accept = page.getByRole('button', { name: 'Accept cookies' });
if (await accept.isVisible()) {
await accept.click();
}
});
34
An axe scan reports 40 violations on a legacy page. How do you add accessibility checks without blocking every build?
Show answer
Record the current violations as a known baseline, for example by snapshotting violation ids and targets, and fail only on new ones. Fix the worst issues first, such as missing labels and contrast on key flows, and shrink the baseline every sprint. Make new pages and components meet zero violations from day one. Report the trend to the team so the debt is visible rather than silently ignored.
35
How do you send authentication headers?
Show answer
Set extraHTTPHeaders in the config or pass headers per request, for example Authorization: Bearer token fetched in a setup step.
36
How do you integrate Playwright with Allure or other reports?
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.
