01
How do you listen to all network requests on a page?
Subscribe to events: page.on('request', r => ...), page.on('response', r => ...) and page.on('requestfailed', r => ...). You can log URLs, collect API calls or count failures. Unlike route, listeners only observe and cannot change traffic. They are handy for checks like 'no request returned a 5xx status during this flow'.
02
What does force: true do on an action, and why should you avoid it?
force: true skips the actionability checks, so Playwright clicks even if the element is hidden, disabled or covered. It can make a test pass while a real user would be blocked. Use it only for special cases like a custom checkbox whose real input is visually hidden by design. Otherwise fix the cause, such as an overlay.
03
How do you test how the UI handles a 500 error from the orders API?
Mock the endpoint with route.fulfill({ status: 500, json: { message: 'Server error' } }), then open the page. Assert the user sees a friendly error message and a retry button, and that no broken half-rendered table appears. Then make the retry return 200 and check the data loads. This covers a path that is hard to trigger on a real server.
04
Mocked responses drift from the real API and tests pass while production breaks. How do you prevent this?
Generate mock data from the API schema or real recorded responses instead of hand-writing it. Validate mocks against the OpenAPI schema in a unit test. Add contract tests on the backend side and re-record HAR files on a schedule. Keep a few unmocked end-to-end tests that run after each deploy. Treat mock files as code with owners and reviews.
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.
07
Write a typed helper that retries an async function a few times.
For most tests, avoid the pop-up: get a session through a test login API or a test identity provider and save it with storageState. Keep one test for the real flow, using const popup = page.waitForEvent('popup') before clicking, then fill the provider's form inside popup. Third-party pages can change and add captchas, so limit how often you depend on them.
09
How do you mock one GraphQL query when all calls go to /graphql?
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.
13
How do you set up Playwright component testing in an existing React project?
Run npm init playwright@latest -- --ct and choose React. It installs @playwright/experimental-ct-react, creates playwright-ct.config.ts and adds a playwright folder containing index.html and index.tsx. index.html hosts the mounted component and index.tsx is where global styles, themes and providers go. Tests then live in files such as Button.spec.tsx and run with npx playwright test -c playwright-ct.config.ts.
14
How do you fail a test if the page logs any console error?
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.
16
How would you structure a large Playwright framework for a team?
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.
In a fixture or beforeEach, call the API (request.post) to create the user or order, use it in the UI test, then delete it in teardown. It is faster and more reliable than creating data through the UI.
21
What are the risks of relying on an experimental testing feature in a large codebase?
APIs may change between minor versions, so upgrades can break many tests at once, and documentation or community examples are thinner. To reduce risk, pin versions, wrap mount setup in shared helpers, keep stories simple and read release notes before upgrading. Also keep the end-to-end suite healthy so you are not dependent on one tool for all UI confidence.
22
How do you assert an element's CSS class, attribute or value?
Situation: a manager wanted 50 tests for a release in one week. Task: deliver without creating a flaky suite. Action: I agreed on the 20 highest-risk flows first, used stable locators and shared fixtures, and listed the rest as follow-ups. Result: the 20 tests ran green in CI from day one and the rest were added next sprint.
24
Write a test that checks keyboard Tab order through a login form.
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.
A discriminated union is a union of object types that share one literal field, such as status: 'ok' with data, or status: 'error' with a message. Checking the status field narrows the type, so TypeScript only allows data in the ok branch. In test helpers this forces you to handle the error case and prevents reading fields that do not exist.
30
How do you test that the app retries a request that failed the first time?
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.
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.
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.
35
What is the difference between getByText and getByLabel?
getByText matches visible text anywhere on the page, so it suits paragraphs, links and messages. getByLabel finds a form control through its associated label element, aria-label or aria-labelledby, so it is the right choice for inputs such as Email or Password. Using getByLabel for inputs also checks that labels are wired correctly, which getByText cannot do.
36
What is the difference between unknown and any in TypeScript?
any switches off type checking, so any property access compiles even if it crashes at runtime. unknown accepts any value but forces you to narrow or validate it before use. For API JSON in tests, typing it as unknown and then validating or asserting a type is safer than any, because mistakes appear at compile time.
37
A locator matches three Delete buttons and the test fails with a strict mode violation. How do you fix it?
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.
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.
39
Describe how you mentored junior engineers on your test framework.
Situation: three interns joined with little automation experience. Task: make them productive without lowering quality. Action: I ran short sessions on fixtures, locators and traces, paired with each of them on a first test, and gave detailed but kind review comments. Result: within a month they each shipped stable tests, and one later improved our reporting script.
40
How do you test geolocation, permissions and time zones?
Set them in the context options (geolocation, permissions, timezoneId, locale) to simulate users from other regions.
