How do you verify a page's URL and title after navigation?

Locators and AssertionsMedium

Show answer

await page.getByRole('link', { name: 'Orders' }).click(); await expect(page).toHaveURL(/\/orders$/); await expect(page).toHaveTitle('My Orders | Shop'); // both retry, so no need to wait for navigation manually

What does the reportSlowTests option do?

Parallel Runs, Sharding & ReportingMedium

Show answer

reportSlowTests makes Playwright list test files that took longer than a threshold at the end of the run. You set max, the number of files to show, and threshold in milliseconds, for example { max: 5, threshold: 60000 }. It is a cheap way to find files worth splitting, because one slow file can hold up a worker or a whole shard.

How do access modifiers help in page object classes?

JavaScript and TypeScriptMedium

Show answer

private and protected hide internal locators and helper steps, so tests can only call meaningful public methods such as login or addToCart. This keeps tests readable and lets you change internals without breaking callers. readonly on the page field prevents it from being replaced. TypeScript enforces these at compile time only, not at runtime.

How does Playwright compare with Selenium and Cypress?

Playwright CoreMedium

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.

How do you test that the app retries a request that failed the first time?

Network MockingMedium

Show answer

Register a route with a counter: on the first call use route.fulfill with status 503, and on later calls fulfil with a success body. Perform the action, then assert the UI shows the final data and the counter equals 2. You can also check that no error message flashed. This proves the retry logic works without waiting for a real outage.

An endpoint should reject invalid email addresses. Which negative tests would you write?

API TestingMedium

Show answer

Cover empty string, missing field, null, wrong type such as a number, no at sign, no domain, spaces, very long strings and a duplicate existing email. For each, assert a 400 or 422 status, a clear error message naming the field, and that nothing was created. Also check that a valid email with uppercase letters is accepted.

How do you structure environment-specific configs in Playwright?

Framework Design and CI/CDMedium

Show answer

Use dotenv files per environment, read them in playwright.config and set baseURL and credentials from variables, selecting with an ENV flag.

What is the difference between await expect(locator) and a plain expect on a value?

Locators and AssertionsEasy

Show answer

await expect(locator).toHaveText('Paid') is a web-first assertion: it retries until the element matches or the timeout ends. expect(value).toBe('Paid') is a generic assertion that checks a value once, immediately. Use web-first assertions for anything on the page and generic ones for plain data such as an API JSON field you already have.

How do you test pagination or chained API calls?

API TestingMedium

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.

A third-party analytics script makes tests slow and flaky. What do you do?

Network MockingMedium

Show answer

Block it in tests with context.route on its domain and route.abort, or fulfill it with an empty script. Analytics is not what you are testing, and blocking it removes delays and random network errors. If tracking events matter, write a few separate tests that capture the requests with waitForRequest and assert their parameters.

What are automatic fixtures?

Fixtures and HooksMedium

Show answer

A fixture defined with { auto: true } runs for every test even when the test does not ask for it. It is useful for cross-cutting work such as attaching console logs on failure, setting a feature flag or checking for leftover data. Keep auto fixtures light, because they add cost to every test in the suite.

How do you open a trace file?

Debugging and Trace ViewerEasy

Show answer

Download trace.zip from the test results or CI artifact. Run npx playwright show-trace path/to/trace.zip to open it locally, or drag the file into trace.playwright.dev, which processes it in the browser without uploading it. In the HTML report, failed tests with a trace show a trace link you can click directly.

What is the difference between beforeEach and fixtures?

Fixtures and HooksMedium

Show answer

beforeEach runs the same code before every test in scope; fixtures are lazy, composable and only set up what a test uses.

What does the waitUntil option of page.goto do?

Playwright CoreEasy

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.

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.

What is the difference between synchronous and asynchronous code?

JavaScript and TypeScriptMedium

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.

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

JavaScript and TypeScriptMedium

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.

Describe a time you convinced developers to add accessible labels or test ids.

Locators and AssertionsMedium

Show answer

Situation: many inputs had no labels, so our tests relied on long CSS selectors that broke often. Task: get stable hooks without slowing developers. Action: I listed the worst screens, showed how getByLabel tests read and how the same labels help screen reader users, and offered to raise small pull requests myself. Result: the team added labels to new work as a rule and locator breakages dropped sharply.

What are the options for the trace setting in playwright.config?

Debugging and Trace ViewerMedium

Show answer

Values are 'off', 'on', 'retain-on-failure', 'on-first-retry' and 'on-all-retries'. 'on-first-retry' records only when a failed test is retried, which keeps the normal run fast and gives a trace for flaky failures. 'retain-on-failure' records every test but keeps only failed ones. 'on' records everything and is mainly for local investigation.

A component under test needs a complex class instance as a prop and the test fails to serialise it. What do you do?

Component TestingHard

Show answer

Create a small test story component in a separate file that builds the class instance inside the browser and renders the real component with it. The test then mounts the story with simple props, such as an id or a scenario name. This keeps the data creation on the browser side of the boundary and also documents test scenarios as reusable stories.

How do you design a locator strategy for a team so tests survive UI redesigns?

Locators and AssertionsHard

Show answer

Set a written priority order: role with name, then label, placeholder or text, then test id, and CSS or XPath only as a last resort. Agree with developers to add data-testid on complex widgets. Keep locators inside page objects so a change is fixed in one place. Add a lint rule or review check against long CSS chains and nth-child selectors.

What reporters does Playwright provide?

Framework Design and CI/CDMedium

Show answer

List, dot, line, HTML, JSON and JUnit reporters, plus integrations such as Allure, configurable per environment.

What is the playwright/index.tsx file used for?

Component TestingMedium

Show answer

It is the entry file bundled into the component test page, so it runs in the browser before every mount. You import global CSS, fonts and theme files there, and register beforeMount and afterMount hooks to wrap components in providers such as a router, theme or state store. Keeping this setup in one place means individual tests can mount components without repeating boilerplate.

What are the main data types in JavaScript?

JavaScript and TypeScriptEasy

Show answer

string, number, boolean, null, undefined, symbol, bigint and object (including arrays and functions).

How do you take screenshots and videos?

Debugging and Trace ViewerMedium

Show answer

page.screenshot() for captures and config options use: { screenshot: 'only-on-failure', video: 'retain-on-failure' } for automatic evidence.

What are closures?

JavaScript and TypeScriptMedium

Show answer

A function that remembers variables from its outer scope even after that scope has finished. They are used for private state and factory helpers.

What are arrow functions?

JavaScript and TypeScriptEasy

Show answer

A short function syntax that does not have its own this and arguments, taking them from the surrounding scope.

How do you combine fixtures from several files with mergeTests?

Fixtures and HooksHard

Show answer

When teams define fixtures in separate modules, such as dbTest and a11yTest, mergeTests(dbTest, a11yTest) returns one test object that has all their fixtures. mergeExpects does the same for custom matchers. This keeps fixture modules small and owned by different people. Watch for name clashes, because two modules defining the same fixture name will conflict.

Tell me about a time a pipeline you owned broke just before a release.

Framework Design and CI/CDMedium

Show answer

Situation: on release day the test job failed for every build after a runner image update. Task: unblock the release safely. Action: I compared logs, found missing browser dependencies, pinned the Playwright Docker image version and reran. Result: tests passed within an hour, the release went out on time, and I added an alert for image changes.

How do you organise tests with page object model in Playwright?

Framework Design and CI/CDMedium

Show answer

Create a class that takes a page, defines locators as properties and exposes action methods; instantiate it in a fixture for clean tests.

How do you validate JSON schema?

API TestingMedium

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.

A locator matches three Delete buttons and the test fails with a strict mode violation. How do you fix it?

Locators and AssertionsMedium

Show answer

First scope the locator to the item you mean, for example the row that contains the user's name: page.getByRole('row', { name: 'Ravi Kumar' }).getByRole('button', { name: 'Delete' }). Do not reach for first() or nth() as a quick fix, because the order can change and the test may delete the wrong record. Scoping by meaningful context is stable and readable.

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

Fixtures and HooksMedium

Show answer

How do you handle token refresh in long API test runs?

API TestingMedium

Show answer

Fetch tokens in a fixture with expiry tracking and refresh it when it is about to expire, keeping tests unaware of the details.

How do project dependencies differ from globalSetup?

Fixtures and HooksHard

Show answer

A setup project is a normal test file that other projects list in dependencies. It shows in the HTML report, can use fixtures, and records traces, so failures are easy to debug. globalSetup is a plain function that runs before everything without fixtures or traces. The docs now recommend project dependencies for login and data seeding.

How do you handle GraphQL APIs in Playwright?

API TestingMedium

Show answer

POST the query and variables as JSON to the single endpoint and assert both data and errors fields in the response.

Write a test that compares only the pricing card instead of the full page.

Visual & Accessibility TestingEasy

Show answer

test('pricing card looks right', async ({ page }) => { await page.goto('/pricing'); const card = page.getByRole('region', { name: 'Pro plan' }); // screenshot is clipped to the element await expect(card).toHaveScreenshot('pro-plan.png'); });

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.

What is the use block in playwright.config?

Framework Design and CI/CDEasy

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.

What is the difference between workerIndex and parallelIndex?

Parallel Runs, Sharding & ReportingMedium

Show answer

workerIndex is a unique number for every worker process started during the run, so it keeps growing when a worker is restarted after a failure. parallelIndex is a slot number from 0 to workers minus 1, and a restarted worker reuses its slot. Use parallelIndex, also exposed as TEST_PARALLEL_INDEX, to pick a fixed test account or database per slot.
