What do locator.and() and locator.or() do?

Locators and AssertionsMedium

Show answer

and() returns a locator that matches elements satisfying both locators, for example a button that also has a certain title. or() matches either locator, which helps when the UI may show one of two states, such as a New email button or a security dialog. With or(), wrap the assertion carefully, because if both appear the strict check fails.

Which frameworks does Playwright component testing support?

Component TestingEasy

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.

Why should you dispose an APIRequestContext?

API TestingMedium

Show answer

A context created with request.newContext() holds cookies, connections and stored responses in memory. Calling await context.dispose() frees them, and any later call on it fails. Without disposing, long runs can leak memory. The built-in request fixture is disposed automatically, so this matters for contexts you create in fixtures or helpers.

Write a test that updates a user with PUT and verifies the change.

API TestingMedium

Show answer

test('update user', async ({ request }) => { const res = await request.put('/api/users/12', { data: { name: 'Neha', city: 'Jaipur' }, }); expect(res.status()).toBe(200); const get = await request.get('/api/users/12'); expect(await get.json()).toMatchObject({ name: 'Neha', city: 'Jaipur' }); });

How do you handle iframes in Playwright?

Playwright CoreMedium

Show answer

Use page.frameLocator('#frame').getByRole(...) so actions work inside the iframe with auto-waiting.

How do you send query parameters in an API request?

API TestingEasy

Show answer

// GET /api/products?category=books&page=2 const res = await request.get('/api/products', { params: { category: 'books', page: 2 }, }); expect(res.ok()).toBeTruthy(); const body = await res.json(); expect(body.items.length).toBeGreaterThan(0);

How do you combine API and UI tests?

API TestingMedium

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.

How do you test API error scenarios?

API TestingMedium

Show answer

Send invalid payloads or missing auth and assert 400, 401 or 404 codes and the error message bodies.

Write a fixture that gives each parallel worker its own test account.

Parallel Runs, Sharding & ReportingMedium

Show answer

import { test as base } from '@playwright/test'; export const test = base.extend<{}, { account: { email: string; password: string } }>({ account: [async ({}, use, workerInfo) => { const i = workerInfo.parallelIndex; await use({ email: `qa.user${i}@example.test`, password: process.env.QA_PASSWORD!, }); }, { scope: 'worker' }], });

What does the github reporter do?

Parallel Runs, Sharding & ReportingEasy

Show answer

The github reporter prints failures in the format GitHub Actions understands, so each failed test appears as an annotation on the right line of the pull request diff. It is usually combined with the html or blob reporter, for example reporter: process.env.CI ? [['github'], ['html']] : 'list'. It saves reviewers from digging through raw logs.

How do you provide page objects as fixtures?

Fixtures and HooksMedium

Show answer

type Pages = { loginPage: LoginPage; cartPage: CartPage }; export const test = base.extend<Pages>({ loginPage: async ({ page }, use) => { await use(new LoginPage(page)); }, cartPage: async ({ page }, use) => { await use(new CartPage(page)); }, }); // test('x', async ({ loginPage }) => { ... })

How do you handle a new tab?

Playwright CoreEasy

Show answer

const [newPage] = await Promise.all([ context.waitForEvent('page'), page.getByText('Open').click(), ]); await newPage.waitForLoadState();

How do you validate response headers?

API TestingMedium

Show answer

Use response.headers() for an object of lower-cased header names, or headersArray() for duplicates. Assert content-type contains application/json, cache-control matches the policy, and security headers such as strict-transport-security are present. Also check that sensitive headers like server version are not exposed. Header checks catch configuration bugs that body checks miss.

How do you share one authenticated API context across all tests in a worker?

Fixtures and HooksMedium

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.

How do you fail a test if the page logs any console error?

Debugging and Trace ViewerMedium

Show answer

test('no console errors', async ({ page }) => { const errors: string[] = []; page.on('console', m => { if (m.type() === 'error') errors.push(m.text()); }); page.on('pageerror', e => errors.push(e.message)); await page.goto('/dashboard'); expect(errors).toEqual([]); });

An API returns 200 but the body contains an error field. How should your test catch this?

API TestingMedium

Show answer

Never trust status alone. Assert the body structure, for example that error is absent and data has the expected fields, ideally with a schema check. Report the issue, because returning 200 for errors breaks clients and monitoring. Add a helper that validates both status and body shape so every test checks it consistently.

How do you run tests against a preview deployment created for each pull request?

Framework Design and CI/CDHard

Show answer

Make baseURL come from an environment variable, such as process.env.BASE_URL, with a default for local runs. In the pipeline, wait for the preview deployment to be ready, read its URL from the deployment step and pass it to the test job. Add a quick health check request first, so a failed deployment is reported clearly instead of as hundreds of test failures.

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

API TestingMedium

Show answer

await request.post('/api/users', { data: { name: 'Asha' } }) automatically sets JSON headers and serialises the payload.

How do you wait for a network response in Playwright?

Network MockingMedium

Show answer

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

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

Network MockingMedium

Show answer

Use page.route to intercept the call and fulfil it with fixed JSON so tests do not depend on external systems.

What is UI mode and how is it different from --debug?

Debugging and Trace ViewerMedium

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.

How do you check a checkbox and verify it is checked?

Playwright CoreEasy

Show answer

const terms = page.getByRole('checkbox', { name: 'I agree to the terms' }); await terms.check(); await expect(terms).toBeChecked(); await terms.uncheck(); await expect(terms).not.toBeChecked(); // setChecked(true) works for both cases

Why choose Playwright over Selenium?

Playwright CoreMedium

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.

Test data is left behind when tests fail midway. How do you guarantee cleanup?

Fixtures and HooksMedium

Show answer

Create the data inside a fixture and delete it after await use(). Fixture teardown runs even when the test fails or times out, so cleanup is reliable. Avoid cleanup steps at the end of the test body, because they never run after a failed assertion. As a safety net, tag test data with a prefix and run a nightly cleanup job.

A trace shows the click landed on an overlay instead of the button. How do you fix it?

Debugging and Trace ViewerMedium

Show answer

The call log will say another element intercepts pointer events. Find what the overlay is, such as a loading mask, cookie banner or chat widget. Wait for it to disappear with expect(overlay).toBeHidden(), or close it in a fixture. Do not use force: true, because it hides a real issue: a user would also be blocked by that overlay.

How do you handle multiple tabs or pop-ups?

Playwright CoreMedium

Show answer

Wait for the popup event with const [popup] = await Promise.all([page.waitForEvent('popup'), page.click('a')]), then interact with popup.

How do you attach axe results to the Playwright HTML report?

Visual & Accessibility TestingMedium

Show answer

test('cart is accessible', async ({ page }, testInfo) => { await page.goto('/cart'); const results = await new AxeBuilder({ page }).analyze(); await testInfo.attach('axe-results', { body: JSON.stringify(results.violations, null, 2), contentType: 'application/json', }); expect(results.violations).toEqual([]); });

How do you keep test code, page objects and utilities organised as a repository grows?

Framework Design and CI/CDMedium

Show answer

Use a clear layout: tests grouped by feature, a pages folder for page objects, a fixtures folder that exposes them, and api and data folders for helpers and builders. Add path aliases in tsconfig, a lint config with the Playwright plugin, and a short contributing guide. Review new helpers in pull requests so duplicate utilities do not spread.

Component and end-to-end tests run together and slow down every commit. How do you separate them?

Component TestingMedium

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.

What is npm and package.json?

JavaScript and TypeScriptEasy

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.

When should you use getByTestId?

Locators and AssertionsEasy

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.

Write a typed helper that retries an async function a few times.

JavaScript and TypeScriptMedium

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; }

Write a component test that checks an onSubmit callback receives the form data.

Component TestingMedium

Show answer

test('submits the entered name', async ({ mount }) => { const submitted: string[] = []; const component = await mount( <NameForm onSubmit={(name) => submitted.push(name)} /> ); await component.getByLabel('Name').fill('Asha'); await component.getByRole('button', { name: 'Submit' }).click(); await expect.poll(() => submitted).toEqual(['Asha']); });

What is the blob reporter and why does it exist?

Parallel Runs, Sharding & ReportingMedium

Show answer

The blob reporter writes a compact archive of everything about a run, including results, attachments and traces, into the blob-report folder. It is meant for machines rather than people. Each shard produces one blob, and npx playwright merge-reports later combines them into a single HTML, JUnit or JSON report. Without it, every shard would produce its own separate HTML report.

What is locator strictness in Playwright?

Locators and AssertionsMedium

Show answer

Locators are strict: an action such as click or fill throws a strict mode violation if the locator matches more than one element. This prevents a test from silently clicking the wrong item. Fix it by making the locator more specific with a name, filter or chaining. Methods like count(), all() or first() are allowed to work with many matches on purpose.

What happens before and after await use() in a fixture?

Fixtures and HooksMedium

Show answer

Code before await use(value) is setup and runs before the test. use hands the value to the test and waits while the test runs. Code after it is teardown and runs when the test finishes, even if it failed. This keeps setup and cleanup for one resource in one place, which is cleaner than a separate beforeEach and afterEach pair.
