01
How do you verify a page's URL and title after navigation?
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
02
How do you debug a test in VS Code with the Playwright extension?
Install the Playwright Test for VS Code extension. Open the Testing panel to see tests, then set a breakpoint in the test file and click Debug Test. Execution stops at the breakpoint with the browser open, so you can inspect variables. Turn on Show browser to watch runs, and use Pick locator or Record at cursor to add steps.
03
How do you organise tests with page object model in Playwright?
Make each test own its data. Create the record inside the test or a fixture with a unique name, such as one using a timestamp or the worker index, and delete it in teardown. Avoid shared seed records for anything that gets modified. Shared read-only reference data is fine. This also lets tests run fully in parallel.
08
How do you mock a paginated endpoint that returns different data per page?
An end-to-end test opens the full deployed app, logs in and goes through pages backed by a real server. A component test mounts one component in isolation with props you control, so there is no backend, routing or login. Component tests are faster and pinpoint the failing piece, while end-to-end tests prove the parts work together. A healthy suite has many component tests and fewer end-to-end journeys.
10
How do you assert that a request was sent with the correct payload?
Replace class-based selectors with role, label and text locators, and agree on data-testid for widgets without good semantics. Move all locators into page objects so future changes touch one file. Add a code review rule and a lint check that flags raw CSS selectors. Share a short locator guide with developers so they know which attributes tests depend on.
// scan the page but skip the chat widget you do not own
const results = await new AxeBuilder({ page })
.include('main')
.exclude('#third-party-chat')
.disableRules(['duplicate-id'])
.analyze();
expect(results.violations).toEqual([]);
// log a ticket for anything you exclude
15
What is expect(...).toPass and how is it different from expect.poll?
toPass retries a whole block of code, including several actions and assertions, until it runs without throwing. expect.poll retries only one function that returns a value. Use toPass for flows like 'click refresh, then check the status' that must be repeated together. It has no timeout by default, so always pass a timeout to avoid a hung test.
16
How do you integrate Playwright with Allure or other reports?
ES modules use import and export and are the modern standard, loaded statically. CommonJS uses require and module.exports and is the older Node.js style. Playwright supports both, and TypeScript test projects usually write import syntax. Mixing them causes errors such as require is not defined, so set type in package.json and tsconfig consistently.
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.
Use the official Playwright image which contains browsers and dependencies, mount the project and run npx playwright test for consistent CI environments.
21
Test data is left behind when tests fail midway. How do you guarantee cleanup?
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.
22
Does headless mode behave differently from headed mode?
Modern Chromium headless uses the same browser code as headed, so behaviour is very close. Differences still appear in viewport size, GPU rendering, fonts and some OS dialogs. Tests should set an explicit viewport and not depend on window focus. If something passes headed but fails headless, record a trace and compare screenshots.
23
How do you design a locator strategy for a team so tests survive UI redesigns?
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.
24
What do maxDiffPixels, maxDiffPixelRatio and threshold control in a screenshot comparison?
threshold sets how different two pixels can be in colour, from 0 to 1, before they count as different; the default is 0.2. maxDiffPixels allows a fixed number of differing pixels, and maxDiffPixelRatio allows a fraction of the total image. Keep them tight so real regressions fail, and set them in the expect section of the config rather than loosening single tests one by one.
Run it many times in isolation: npx playwright test cart.spec.ts -g 'apply coupon' --repeat-each=30 --workers=4 --trace=on. Repeating it with several workers creates the timing pressure CI has. Add --retries=0 so failures are not hidden. Once it fails, open the trace for that run and compare it with a passing run.
26
How do test.slow() and longer timeouts help or hurt debugging?
test.slow() triples the timeout for a test that is genuinely long, such as a report export. It is honest and visible in code. But raising timeouts to make a flaky test pass hides the real cause, such as a missing wait or slow backend, and makes failures take longer. Investigate the trace first and change timeouts only with a reason.
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.
Destructuring pulls values from arrays or objects into variables; spread expands an array or object into another, useful for copying and merging config.
29
A third-party analytics script makes tests slow and flaky. What do you do?
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.
30
How do you verify that an API returns consistent data across two versions of an endpoint?
Call both versions, for example /v1/orders/42 and /v2/orders/42, with the same test data. Map the fields that should match, since names may differ, and compare them with toEqual. Also assert that fields removed in v2 are really absent and new ones have correct types. Running this during a migration catches breaking changes before clients switch.
31
How do you record a trace manually with the tracing API?
Call await context.tracing.start({ screenshots: true, snapshots: true }) before the steps, and await context.tracing.stop({ path: 'trace.zip' }) after them. This is useful in scripts that use the library without the test runner, or when you want a trace of only part of a flow. tracing.group can label sections of steps.
toBeAttached only checks that the element exists in the DOM. toBeVisible also needs it to have a non-empty bounding box and no visibility:hidden style. A hidden modal can be attached but not visible. Use toBeVisible for anything a user should see, and toBeAttached for hidden inputs or elements whose presence matters more than appearance.
Situation: we could not reproduce a bug where the cart broke when the stock API returned zero for one item. Task: cover it with a test. Action: I mocked only the stock endpoint with route.fetch and changed one item's quantity, then asserted the out-of-stock label. Result: the bug was fixed and the test now protects that case on every run.
39
Write a test that deletes a record and confirms it is gone.
import { test, expect } from '@playwright/test';
import AxeBuilder from '@axe-core/playwright';
test('signup page has no WCAG A/AA issues', async ({ page }) => {
await page.goto('/signup');
const results = await new AxeBuilder({ page })
.withTags(['wcag2a', 'wcag2aa', 'wcag21a', 'wcag21aa'])
.analyze();
expect(results.violations).toEqual([]);
});
