Playwright interview questions that you are going to love

Following my previous article about playwright interview questions, here are 9 playwright tricky questions that you don't want to fail

1. The explicit waits

From testing search functionality point of view how would you improve the code below:

test("The explicit waits", async ({ page }) => {
  await page.goto("https://blog.martioli.com/playwright-tips-and-tricks-2/")
  await page.getByText('Playwright tips and tricks #2').scrollIntoViewIfNeeded()
  await expect(page.getByText('Playwright tips and tricks #2')).toBeVisible()
  await expect(page.getByRole('button', { name: 'Search this site' })).toBeVisible()
  await page.getByRole('button', { name: 'Search this site' }).click()
  await expect(page.frameLocator('iframe[title="portal-popup"]').getByPlaceholder('Search posts, tags and authors')).toBeVisible()
  await page.frameLocator('iframe[title="portal-popup"]').getByPlaceholder('Search posts, tags and authors').fill("Cypress")
  await expect(page.frameLocator('iframe[title="portal-popup"]').getByRole('heading', { name: 'Cypress' }).first()).toContainText("Cypress")
});

2. The visible methods

What is this code going to do:

test("The visible methods", async ({ page }) => {
  await page.goto("https://blog.martioli.com/");
  await expect(page.getByRole('link', { name: 'About' }).isVisible())
});

Possible answers:

• Test will fail because isVisible() is not a valid method that can be used
• Test will fail with an error about property 'then'
• Test will pass

3. The ninja click

Given the code below, what do you think it will happen

test("The ninja", async ({ page }) => {
  await page.goto("https://www.clickspeedtester.com/mouse-test/");
  await page.getByRole('link', { name: 'Second Clicker' }).click({ trial: true })
  await page.waitForURL("**/clicks-per-second-test/")
})

Possible answers:

• Test will fail with error page.waitForURL: Test ended, because click was not performed
• Test will fail because waitForURL() argument is not in valid format
• Test will fail at click step, there is no such thing as trial:true

4. The you OK ?

Given the code below, what do you think it will happen

test("The you OK", async ({ page }) => {
  const response = await page.request.get('https://blog.martioli.com/');
  await expect(response).toBeOK();
})

Possible answers:

• Test will fail because there is no such thing as toBeOK()
• Test will fail because page does not have request
• Test will pass

5. The special word

Given the element has the text "Be the first to discover new tips and tricks about automation in software development" , in the code below, what do you think will happen

test("The innerText?", async ({ page }) => {
  await page.goto('https://blog.martioli.com');
  const innertText = page.locator(".gh-subscribe-description").innerText()
  await expect(innertText).toContain("Be the first to discover new tips")
});

Possible answers:

• Test will pass
• Test will fail with Error: expect Received object: {}
• Test will fail because we cannot use toContain() on innerText()

6. The magic filter

What is the best and most recommended way to filter tests ?

7. The fail one

Given the code below and the fact that I am not an astronaut, what do you think will happen

test("The fail", async ({ page }) => {
  test.fail()
  await page.goto("https://www.martioli.com/");
  await expect(page.getByText('Astronaut')).toBeVisible()
});

Possible answers:

• Test will pass because of the test.fail() method applied
• Test will fail because of the test.fail() method applied
• Test will perform all the steps but still have a result as fail

8. The health check

Given the code below, what do you think will happen and how you can improve the code

const locales = [
  "de",
  "com",
  "es"
]

for (const location of locales) {
  test(`check health: ${location}`, async ({ page }) => {
    const response = await page.request.get(`https://www.google.${location}/`)
    expect(response).toBeOK()
  });
}

Possible answers:

• Test will pass
• Test will fail because you cannot do such for loops
• Test will fail because expect has no await key

9. The page one

Given the code below, what do you think will happen

test("The page one", async ({ page }) => {
  await page.goto("https://blog.martioli.com/");
  await expect(getByText('Recommended Resources')).toBeVisible()
});

Possible answers:

• Test will pass because we have Recommended Resources
• Test will fail because of Reference Error
• Test will fail because there is no Recommended Resources text on my blog

Hit the clap button if you found this useful. Or even buy me a coffee if you want to motivate me even more.
