01
What happens before and after await use() in a fixture?
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.
02
How do you test geolocation, permissions and time zones?
webServer tells Playwright to start your app with a command, such as npm run start, and wait until a URL or port responds before running tests. reuseExistingServer: !process.env.CI lets you use an already running dev server locally. You can define several servers, for example frontend and a mock API. It shuts them down after the run.
04
How do you rerun only the tests that failed in a sharded CI run?
--last-failed works only on the machine that kept the .last-run.json file, so it does not help across shards. Instead collect the failed tests from the merged JSON report or the blob reports, then run them in a follow-up job by file and line or with --grep on their titles. Many teams simply rely on retries and treat any test needing a rerun as flaky.
A failed test may leave the browser or worker-scoped fixtures in a bad state, such as an open dialog or corrupted login. To protect the remaining tests, Playwright throws that worker away and starts a fresh one for the next tests. This means worker fixtures run again and beforeAll hooks may run more than once, which is normal and something your setup must tolerate.
08
A component test passes alone but fails when the full component suite runs. What do you check?
Look for state that leaks between mounts: global stores or singletons created at module level in index.tsx, timers or listeners not cleaned up on unmount, and shared mock data mutated by one test. Make the providers create fresh state in beforeMount each time and reset mocks per test. Running with --repeat-each and a single worker often reproduces the leak quickly.
09
What happens the first time toHaveScreenshot runs and no baseline image exists?
Playwright cannot compare anything, so it captures the screenshot, saves it as the new baseline in the snapshots folder and marks the test as failed with a message that the snapshot was missing. On the next run the test compares against that file. This is why you review new baselines before committing them, and why baselines should be generated in the same environment that CI uses.
10
Why are component tests usually faster than end-to-end tests?
They skip the expensive parts: no full app start, no backend calls, no login and no navigation through several pages. Playwright builds the component bundle once and each test simply mounts into an already loaded page. A typical component test finishes in well under a second, so hundreds can run in a pull request check, while end-to-end flows take several seconds each.
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.
maxFailures stops the run after a set number of test failures, for example maxFailures: process.env.CI ? 10 : undefined. If an environment is down and every test fails, the build stops early instead of burning an hour of CI time. Set it high enough that a few real failures still show their full picture.
16
A trace shows the click landed on an overlay instead of the button. How do you fix it?
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.
Listen with page.on('console', msg => ...) for console.log, warnings and errors, and page.on('pageerror', err => ...) for uncaught exceptions. Collect them in an array and attach them to the report on failure. Traces also show console output. Uncaught page errors often explain why a button did nothing or a page stayed blank.
19
A fixture mocks every /api call, but one test needs a different response for /api/cart. How do you override it?
Register a new page.route for /api/cart inside that test. Handlers run in reverse order of registration, so the newer one runs first. Fulfil the cart request with the special data, and for anything else call route.fallback() so the request moves on to the fixture's general handler. This keeps the shared mock untouched and makes the override local and easy to read.
20
How do you read a Playwright timeout error message?
The error names the action and locator, for example locator.click: Timeout 30000ms exceeded, followed by a call log. The call log lists each attempt, such as waiting for the element to be visible, enabled and stable, or another element intercepting pointer events. The last lines show what blocked the action. Read it before changing timeouts.
21
How do you run tests in parallel and control workers?
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.
23
A test must confirm that an error banner does not appear, but it always waits the full timeout. How do you fix it?
Use a web-first negative assertion such as await expect(banner).toBeHidden() or not.toBeVisible(); they pass as soon as the element is absent, so they do not wait the full timeout. The real problem is timing: assert after a positive signal, such as the success message appearing, otherwise the banner may simply not have rendered yet and the check passes too early.
24
How is a Playwright component test different from a Jest unit test with jsdom?
jsdom is a JavaScript imitation of the DOM running in Node, so layout, CSS, real focus and many browser APIs are missing or fake. A Playwright component test renders in real Chromium, Firefox or WebKit, so visibility, scrolling, styles and keyboard behaviour are real. The cost is a build step and a browser, so it is slower than jsdom. Pure logic and hooks are still cheaper in unit tests.
25
What do toHaveAccessibleName and toHaveAccessibleDescription check?
They assert the name and description that assistive technology computes for an element, using the accessibility tree rather than raw attributes. The name may come from a label, aria-label, aria-labelledby or inner text, and the description often from aria-describedby. For example an icon-only close button should have the name Close. These checks catch problems that a plain text assertion would miss.
26
What are the options for the trace setting in playwright.config?
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.
27
An API returns 200 but the body contains an error field. How should your test catch this?
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.
28
A test fails only in WebKit. How do you investigate?
Run it alone with --project=webkit --headed and record a trace. Compare it with the Chromium trace to see where behaviour differs, such as date input format, scrolling, font rendering or a missing browser API. Check the app's support matrix. If it is a real product bug, raise it, and skip the test for WebKit with a linked ticket until it is fixed.
29
How do you add build details such as the commit and environment to the test report?
Set the metadata field in playwright.config, for example metadata: { commit: process.env.GIT_SHA, env: process.env.TEST_ENV }, which reporters can read and recent HTML reports show. Inside tests use testInfo.annotations.push for per-test details like a ticket id. Custom reporters can read config.metadata in onBegin and include it in messages or uploads.
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.
32
How do you test that a modal dialog traps focus and returns it when closed?
Open the dialog with a button and assert the dialog role is visible and focus moved inside it. Press Tab more times than there are controls and check with toBeFocused that focus never leaves the dialog. Press Escape, assert the dialog is hidden, and check that the opening button is focused again. Running the same test with Shift+Tab covers backward navigation as well.
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.
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.
