02
What are web-first assertions?
Show answer
Assertions like expect(locator).toBeVisible() that retry until they pass or time out, unlike one-off checks.
03
Why mock the network in UI tests at all?
Show answer
Mocking makes tests fast, stable and independent of backend data or third-party outages. It also lets you test states that are hard to create for real, such as empty lists, errors or huge responses. The trade-off is lower confidence that frontend and backend work together, so keep some unmocked end-to-end tests for critical journeys.
04
What does eslint-plugin-playwright help with?
Show answer
It is a lint plugin with rules for common Playwright mistakes, such as missing await on assertions, leftover test.only or page.pause, forced clicks, fixed waits with waitForTimeout and element handles instead of locators. Running it in pull requests stops bad patterns before review. Teams usually enable the recommended rule set and add a few stricter rules over time.
05
How do you locate elements inside a specific row or card?
Show answer
Chain locators: find the container first, then search inside it. Example: page.getByRole('row', { name: 'INV-104' }).getByRole('button', { name: 'Download' }). Each step narrows the search area, so short names like Edit or Download stay unique. Chaining also documents intent clearly and avoids long CSS paths that break when markup changes.
06
How do you simulate a slow API to test a loading spinner?
Show answer
await page.route('**/api/report', async route => {
await new Promise(r => setTimeout(r, 3000));
await route.continue();
});
await page.getByRole('button', { name: 'Generate' }).click();
await expect(page.getByRole('progressbar')).toBeVisible();
await expect(page.getByRole('progressbar')).toBeHidden();
07
Why can beforeAll run more than once in a Playwright run?
Show answer
Each worker is a separate process with its own state. When tests from a file are split across workers, or a worker restarts after a failure, beforeAll runs again in the new worker. So never assume it runs only once globally. For one-time setup across the whole run, use a setup project with dependencies or globalSetup.
08
Why use readonly and as const for test data?
Show answer
readonly and as const stop test data from being changed by accident, for example one test editing a shared user object and breaking the next. as const also keeps literal types, so ['admin', 'viewer'] as const gives the type 'admin' | 'viewer'. That lets TypeScript reject invalid roles at compile time instead of during a run.
09
How do you provide page objects as fixtures?
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 }) => { ... })
10
Test data is left behind when tests fail midway. How do you guarantee cleanup?
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.
11
How do you mock network requests?
Show answer
page.route('**/api/items', route => route.fulfill({ json: [...] })) intercepts and replies with test data; route.abort() simulates failures.
12
How do you run tests on mobile viewports?
Show answer
Use device descriptors such as devices['iPhone 13'] in a project config to emulate viewport, user agent and touch.
13
How do you test accessibility with Playwright?
Show answer
Integrate axe-core through @axe-core/playwright, run an analysis on the page and assert that there are no violations.
14
Promise.all vs Promise.allSettled vs Promise.race?
Show answer
all waits for every promise and rejects on the first failure; allSettled waits for all and reports each outcome; race settles with the first one to finish.
15
How do you test a file download?
Show answer
const [download] = await Promise.all([
page.waitForEvent('download'),
page.getByText('Export').click(),
]);
await download.saveAs('reports/file.csv');
16
How do you change part of a real API response?
Show answer
await page.route('**/api/profile', async route => {
const response = await route.fetch();
const json = await response.json();
json.plan = 'premium';
await route.fulfill({ response, json });
});
await page.goto('/account');
await expect(page.getByText('Premium plan')).toBeVisible();
17
What does the reportSlowTests option do?
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.
18
A worker-scoped fixture holds shared data and some tests see stale values. How do you fix it?
Show answer
Worker fixtures live across many tests, so any test that changes their data affects the next ones. Keep worker fixtures read-only, such as a connection or a reference catalogue. Move anything a test modifies into a test-scoped fixture that creates fresh data. If sharing is needed for speed, reset the relevant state in the test fixture before use.
19
A locator matches three Delete buttons and the test fails with a strict mode violation. How do you fix it?
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.
20
How do you publish the Playwright HTML report from a CI pipeline?
Show answer
Keep the html reporter in the config. After the test step, add an upload-artifact step that runs even when tests fail, using a condition like always(), and upload the playwright-report folder with a retention period. Team members download and open it with npx playwright show-report. Some teams also publish it to static hosting for direct links.
21
A designer changes the primary button colour and 300 visual tests fail at once. How do you handle it?
Show answer
First confirm the change is intended and check a sample of diffs to make sure nothing else moved. Then regenerate baselines in the CI Docker environment in a separate commit, so reviewers can see only image changes. Longer term, reduce the count: most of those tests should not snapshot full pages. Keep a few page-level shots and move detail checks to component-level screenshots of key states.
22
How do you pass slots and listen to events in a Vue component test?
Show answer
With the Vue package you can mount with an options object: mount(Button, { props: { label: 'Save' }, slots: { default: 'Click me' }, on: { click: handler } }). The on map receives emitted events, so you can push payloads into an array and assert on them. JSX syntax is also supported if the project is configured for it.
23
Tests pass with one worker but fail with eight. How do you debug this?
Show answer
This usually means tests share something: the same user account, the same records or a global server setting. Run the failing file with --workers=8 and --repeat-each to reproduce it. Look at which tests run at the same time in the report. Fix it by giving each test unique data, using workerIndex in names, or isolating shared settings per worker.
24
Show a config with a setup project and a browser project that reuses its login.
Show answer
projects: [
{ name: 'setup', testMatch: /auth\.setup\.ts/ },
{
name: 'chromium',
use: { ...devices['Desktop Chrome'], storageState: '.auth/user.json' },
dependencies: ['setup'],
},
],
25
Tell me about a time an accessibility check caught a real issue before release.
Show answer
Situation: a new checkout redesign was ready for release. Task: I had just added an axe scan to our Playwright smoke tests. Action: the scan flagged that the payment form inputs had placeholder text but no labels, and a keyboard test showed the pay button was unreachable with Tab. I raised it with screenshots and the rule links. Result: the developer fixed both in a day and the release went out on time.
26
Component tests fail because imports like @/utils cannot be resolved, though the app builds fine. How do you fix it?
Show answer
The app uses a bundler alias that the component test bundle does not know. Add the same alias in ctViteConfig under resolve.alias, or reuse the project's Vite config by importing it. Also make sure tsconfig paths match, so editors and type checks agree. After that, clear the cache folder that the component bundler writes under playwright/.cache so the bundle rebuilds.
27
Describe how you handled a flaky test that was blocking releases.
Show answer
Situation: a payment test failed randomly and blocked three release builds. Task: unblock releases without hiding a real problem. Action: I quarantined it with a tag and a ticket, kept it running in a separate job, and used traces from twenty runs to find a missing wait on a redirect. Result: it was fixed in two days and releases continued meanwhile.
28
How do you test offline behaviour?
Show answer
Call context.setOffline(true) to cut all network access for the context, then check that the app shows an offline banner or queues actions. Switch back with setOffline(false) and verify it syncs. You can also set offline: true in the context options. For a single failing endpoint, use route.abort instead of going fully offline.
29
How do you capture browser console messages and page errors?
Show answer
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.
30
Visual tests pass on developers' laptops but fail in CI with tiny font differences. Why, and how do you fix it?
Show answer
Font rendering, anti-aliasing and installed fonts differ between Windows, macOS and Linux, so the same page produces slightly different pixels. The fix is to generate and compare baselines in one fixed environment, usually the official Playwright Docker image used in CI. Developers update baselines by running that container locally or through a CI job, not from their own machines. Loosening thresholds should be the last resort.
31
How do you handle iframes in Playwright?
Show answer
Use page.frameLocator('#frame').getByRole(...) so actions work inside the iframe with auto-waiting.
32
A test passes locally but fails in CI with a timeout on a click. How do you use the trace?
Show answer
Open the CI trace and go to the failed click. Check the action log, which shows what Playwright waited for, such as the element not being visible or another element intercepting pointer events. Compare before and after snapshots and the network tab for slow or failed calls. Common causes are a slower environment, a cookie banner or different screen size.
33
How do you write a custom matcher with expect.extend?
Show answer
expect.extend takes an object of matcher functions. Each receives the received value and arguments, and returns { pass, message, name, expected, actual }. For example a toHaveAmount matcher can read a locator's text, strip the currency symbol and compare numbers, retrying with expect.poll inside. Export the extended expect from a shared fixtures file so all tests use the same version.
34
What are generics in TypeScript?
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.
35
How do you test conditional GET requests that use ETag and If-None-Match?
Show answer
Call the endpoint once and read the etag header from the response. Call it again with the If-None-Match header set to that value and assert status 304 with an empty body. Then change the resource, repeat the conditional call and assert 200 with a new ETag. This proves caching works and that updates are not hidden behind stale responses.
36
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');
37
An endpoint should reject invalid email addresses. Which negative tests would you write?
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.
38
How do you test a component that reads from a global state store?
Show answer
Wrap the mounted component in the store provider inside beforeMount, and use hooksConfig to choose the initial state for each test, such as a logged-in user or an empty cart. Build the store in the browser side of index.tsx, not in the test file. Then interact with the component and assert on the rendered output rather than reading store internals.
39
How do you test a page in dark mode or with reduced motion?
Show answer
Set colorScheme: 'dark' or reducedMotion: 'reduce' in the context options or test.use. You can also switch during a test with page.emulateMedia({ colorScheme: 'dark' }). Then assert the right styles or take a screenshot comparison. Reduced motion also helps stability, because many apps skip animations when that preference is set.
40
How do you test geolocation, permissions and time zones?
Show answer
Set them in the context options (geolocation, permissions, timezoneId, locale) to simulate users from other regions.
