01

What is the difference between getByText and getByLabel?

Locators and AssertionsEasy
Save to ▾
Show answer
getByText matches visible text anywhere on the page, so it suits paragraphs, links and messages. getByLabel finds a form control through its associated label element, aria-label or aria-labelledby, so it is the right choice for inputs such as Email or Password. Using getByLabel for inputs also checks that labels are wired correctly, which getByText cannot do.
02

How do you run a single test or file in Playwright?

Playwright CoreEasy
Save to ▾
Show answer
npx playwright test tests/login.spec.ts, add -g "test title" to match a name, or use test.only while debugging.
03

Write a test that logs in and checks the dashboard heading.

Playwright CoreEasy
Save to ▾
Show answer
test('login', async ({ page }) => { await page.goto('/login'); await page.getByLabel('Email').fill('a@b.com'); await page.getByLabel('Password').fill('secret'); await page.getByRole('button', { name: 'Login' }).click(); await expect(page.getByRole('heading', { name: 'Dashboard' })).toBeVisible(); });
04

How do you handle a new tab?

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

What is the difference between == and === in JavaScript?

JavaScript and TypeScriptEasy
Save to ▾
Show answer
=== compares value and type without conversion, so '5' === 5 is false. == converts types first, so '5' == 5 is true and null == undefined is true. Implicit conversion causes surprising bugs, so test code should always use === and !==. TypeScript and lint rules such as eqeqeq help enforce this.
06

How do you handle a page that opens a browser permission prompt for notifications?

Playwright CoreEasy
Save to ▾
Show answer
Browser permission prompts are not part of the page, so you cannot click them. Instead grant the permission up front with the permissions option in the config or context, for example permissions: ['notifications'], or call context.grantPermissions. To test the denied path, create a context without the permission and assert that the app shows its fallback message.
07

What is the difference between map, filter and reduce?

JavaScript and TypeScriptMedium
Save to ▾
Show answer
map transforms each item, filter keeps items that match a condition, and reduce combines all items into a single value.
08

Why choose Playwright over Selenium?

Playwright CoreMedium
Save to ▾
Show answer
Auto-waiting, a built-in test runner, Chromium/Firefox/WebKit with one API, network interception, the trace viewer and parallel runs out of the box — usually faster and less flaky.
09

What does the channel option do?

Playwright CoreEasy
Save to ▾
Show answer
By default Playwright uses its own bundled Chromium, Firefox and WebKit builds. Setting channel: 'chrome' or 'msedge' in a project runs tests in the installed branded Chrome or Edge browser instead. This is useful when you must test on the exact browser users run, for example for codecs or policies. Install with npx playwright install chrome.
10

How do you select an option from a native select dropdown?

Playwright CoreEasy
Save to ▾
Show answer
const country = page.getByLabel('Country'); await country.selectOption('India'); // by value or label await country.selectOption({ label: 'India' }); await expect(country).toHaveValue('IN'); // multi-select: selectOption(['a', 'b'])
11

What does the mount fixture return?

Component TestingEasy
Save to ▾
Show answer
mount renders the component into the test page and returns a locator pointing at the component root. You can call getByRole, click, and use web-first assertions on it like any locator. It also has helpers: update to re-render with new props or children, and unmount to remove it. Because it is a locator, the auto-waiting and retry behaviour of end-to-end tests applies here too.
12

How do you work with iframes?

Playwright CoreEasy
Save to ▾
Show answer
const frame = page.frameLocator('#payment-frame'); await frame.getByLabel('Card number').fill('4111 1111 1111 1111');
13

What are generics in TypeScript?

JavaScript and TypeScriptMedium
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.
14

Write an API test with the request fixture.

API TestingMedium
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); });
15

How do you read environment variables safely in a TypeScript test project?

JavaScript and TypeScriptMedium
Save to ▾
Show answer
Load a .env file with a package like dotenv in playwright.config, then read process.env.BASE_URL. Values are string | undefined, so validate them early and throw a clear error if a required one is missing. Keep .env out of git and commit an .env.example instead. In CI, set the same names as secret variables.
16

let vs const vs var?

JavaScript and TypeScriptEasy
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.
17

Which frameworks does Playwright component testing support?

Component TestingEasy
Save to ▾
Show answer
Official packages exist for React, Vue and Svelte, named like @playwright/experimental-ct-react and @playwright/experimental-ct-vue. Each package provides the mount fixture and hooks in the style of its framework, such as slots and events for Vue. Support has changed between versions and the feature is experimental, so check the current docs and pin the package version alongside @playwright/test.
18

How do you use keyboard shortcuts in Playwright?

Playwright CoreMedium
Save to ▾
Show answer
Use locator.press('Enter') for a key on a focused element, or page.keyboard.press('Control+A') for page-level shortcuts. Modifiers combine with a plus sign, and ControlOrMeta picks Ctrl on Windows and Linux and Cmd on macOS. keyboard.down and keyboard.up hold keys. Use pressSequentially only when the app needs real keystrokes, such as autocomplete.
19

Tell me about a time you replaced brittle locators in an existing suite.

Locators and AssertionsEasy
Save to ▾
Show answer
Situation: a suite I joined used long XPath selectors and about ten tests broke after every UI release. Task: make them stable. Action: I rewrote the locators with getByRole and getByLabel, added test ids for two custom grids and moved everything into page objects. Result: locator-related failures dropped to almost zero over the next three releases.
20

How do you write data-driven API tests with many inputs?

API TestingMedium
Save to ▾
Show answer
const cases = [ { email: '', status: 400 }, { email: 'bad', status: 400 }, { email: 'ok@test.in', status: 201 }, ]; for (const c of cases) { test(`signup with '${c.email}'`, async ({ request }) => { const res = await request.post('/api/signup', { data: { email: c.email } }); expect(res.status()).toBe(c.status); }); }
21

How do you install and start a Playwright project?

Playwright CoreEasy
Save to ▾
Show answer
Run npm init playwright@latest, which sets up config, example tests and browsers; execute with npx playwright test.
22

Parallel tests create users with the same email and fail with 'already exists'. How do you fix it?

Parallel Runs, Sharding & ReportingMedium
Save to ▾
Show answer
Generate unique data per test, for example by adding testInfo.testId, the parallel index or a random suffix to the email, or by using a data builder that creates a fresh user through the API. Avoid hard-coded shared records in test files. Clean up created users in a fixture teardown so the database does not fill up over time.
23

What is npm and package.json?

JavaScript and TypeScriptEasy
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.
24

How do you handle errors in async code?

JavaScript and TypeScriptEasy
Save to ▾
Show answer
Use try-catch with await, or .catch() on promises, and make sure rejected promises are never left unhandled.
25

What is the difference between a type and an enum in TypeScript?

JavaScript and TypeScriptMedium
Save to ▾
Show answer
A type alias describes a shape or union of values; an enum creates a named set of constants that exists at runtime.
26

A toast message disappears after two seconds and the assertion on it is flaky. How do you test it reliably?

Locators and AssertionsMedium
Save to ▾
Show answer
Assert immediately after the action that triggers it, using a web-first assertion like toBeVisible and toHaveText, which start checking at once. Do not add sleeps before the check. If the toast is still missed, control time with page.clock so it does not auto-hide, or verify the result through the data it confirms, such as the saved record.
27

What is the difference between null and undefined?

JavaScript and TypeScriptMedium
Save to ▾
Show answer
undefined means a variable has not been assigned; null is an intentional empty value.
28

What does the waitUntil option of page.goto do?

Playwright CoreEasy
Save to ▾
Show answer
waitUntil decides when goto considers navigation finished: 'load' waits for the load event and is the default, 'domcontentloaded' waits only for the HTML to parse, 'networkidle' waits for no network for 500 ms, and 'commit' returns when the response starts. Avoid networkidle, which is discouraged and flaky; use assertions on the content you need instead.
29

What is the difference between path parameters and query parameters?

API TestingEasy
Save to ▾
Show answer
Path parameters identify a specific resource and are part of the URL path, like /users/42. Query parameters filter, sort or paginate and follow a question mark, like /users?city=Delhi&page=2. In tests, check invalid path ids return 404, and that each query parameter changes results correctly, including invalid and missing values.
30

What are arrow functions?

JavaScript and TypeScriptEasy
Save to ▾
Show answer
A short function syntax that does not have its own this and arguments, taking them from the surrounding scope.
31

When should you use getByTestId?

Locators and AssertionsEasy
Save to ▾
Show answer
Use getByTestId when no user-facing locator is stable or unique, for example icon-only buttons, dynamic grids or canvas wrappers. It matches the data-testid attribute by default, and you can change the attribute name with testIdAttribute in the config. Test ids are very stable but users never see them, so prefer role, label or text first and keep test ids as a fallback.
32

What does the nullish coalescing operator do?

JavaScript and TypeScriptEasy
Save to ▾
Show answer
a ?? b returns b only when a is null or undefined. Unlike ||, it keeps valid falsy values such as 0, false and an empty string. In config this matters: process.env.RETRIES ?? '2' keeps a value of 0 if someone sets it, whereas || would wrongly replace it. It is often combined with optional chaining.
33

Describe a time a test passed but the feature was actually broken.

Locators and AssertionsMedium
Save to ▾
Show answer
Situation: a checkout test passed, but users saw a blank order summary. Task: find why. Action: I found the test only asserted that the summary container was visible, not its contents. I added assertions on item names, totals and the order id. Result: the test caught the regression, and I reviewed other tests for similar weak assertions.
34

Tell me about the first time you used the trace viewer to solve a failure.

Debugging and Trace ViewerEasy
Save to ▾
Show answer
Situation: during my internship a login test failed only in CI and I could not reproduce it. Task: find the cause. Action: I enabled trace on first retry, downloaded the trace and stepped through the actions, and saw a cookie banner covering the sign-in button in the CI viewport. Result: I added a step to accept the banner, the test became stable, and I shared the method with my team.
35

What is a Promise and what states can it have?

JavaScript and TypeScriptEasy
Save to ▾
Show answer
A Promise represents a value that will be available later, such as an API response. It is pending at first, then either fulfilled with a value or rejected with an error, and it never changes after that. You consume it with await or then and catch. Almost every Playwright call returns a Promise, which is why tests use await so much.
36

What are the main data types in JavaScript?

JavaScript and TypeScriptEasy
Save to ▾
Show answer
string, number, boolean, null, undefined, symbol, bigint and object (including arrays and functions).
37

Describe a time strict TypeScript types caught a bug in your test code.

JavaScript and TypeScriptMedium
Save to ▾
Show answer
Situation: our API helpers returned loosely typed objects and tests often read fields that no longer existed. Task: make helpers safer. Action: I added response interfaces, turned on strict mode and replaced any with unknown plus type guards. Result: the compiler immediately showed eleven tests reading a renamed field, which had been passing because they compared undefined with undefined. We fixed them before the next release.
38

What is hoisting?

JavaScript and TypeScriptMedium
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.
39

How does this behave in arrow functions compared with regular functions?

JavaScript and TypeScriptMedium
Save to ▾
Show answer
A regular function gets this from how it is called, so passing a class method as a callback can lose this. An arrow function has no own this and uses the value from the surrounding code. In page objects, arrow functions in callbacks such as map keep access to this.page, which avoids undefined errors.
40

What actionability checks does Playwright run before a click?

Playwright CoreMedium
Save to ▾
Show answer
Before clicking, Playwright waits until the element is attached, visible, stable (not animating), enabled and able to receive events (not covered by another element). It also scrolls it into view. fill checks for an editable element. If the checks are not met before the timeout, the action fails with a log of what was missing.
