Quiz, Playwright basics

Check what you know

This quiz has ten questions. The questions come from lessons 2 to 14. You need 70 percent to pass, and you can try again.

Read each question slowly. Many wrong answers look right if you read quickly.

Question 1 of 10

Which locator does Playwright recommend as the first choice for a button?

page.locator('div > button')page.getByRole('button', { name: 'Add' })page.locator('.btn-primary')page.getByTestId('add')

Question 2 of 10

A locator matches three elements. Your test calls click() on it. What happens?

Playwright clicks the first element.Playwright clicks all three elements.The test fails with a strict mode violation.Playwright clicks the last element.

Question 3 of 10

What is wrong with this test?

await page.goto('/');
const count = await page.getByTestId('todo-item').count();
expect(count).toBe(3);

count() does not exist in Playwright.expect needs the word await in front.toBe cannot compare numbers.count() reads the page one time, so it can read the list before the list is loaded.

Question 4 of 10

Why is await page.waitForTimeout(2000) a poor way to wait for a page?

It waits for a time, not for a fact. It is slow when the page is fast, and it fails when the page is slower.It does not work in Playwright.It makes the browser close.It can only wait for one second.

Question 5 of 10

Your test passes on the normal app, and it also passes on a copy of the app that has a bug. What does this tell you?

The bug is not a real bug.The app is right.The test does not check the thing that the bug changes.Playwright is not working.

Question 6 of 10

Every test in a group starts with await page.goto('/login'). Where should you put this line?

In every test, so that each test is complete.In a test.beforeEach hook inside the group.In test.afterEach.At the top of the file, outside any function.

Question 7 of 10

What does route.fulfill({ status: 500 }) do?

It sends the request to the server and changes the answer later.It answers the request itself with the status 500. The request never reaches the server.It makes the server return an error for all later tests.It stops the test with an error.

Question 8 of 10

You call page.waitForResponse(...) after the click that sends the request. What is the risk?

None. The order does not matter.The click does not work.The response can arrive before you start to wait, and the test waits until it times out.The response has no status.

Question 9 of 10

Which of these belong in a page object? Pick all that apply.

Choose all answers that apply.

A locator that many tests use.A method for a step of a user, such as addToCart(name).The expect calls that state what each test must check.A wait that makes sure the page is ready.

Question 10 of 10

In a fixture, what runs at the moment that the fixture calls await use(value)?

The next fixture.The cleanup code.The report.The test.

Answer every question to check.
