Popups are common in web applications, from new tabs and login windows to JavaScript alerts and confirmation messages. Learning to handle them is an essential skill for students preparing for a career in automation testing.

What Are Popups in Playwright?

In Playwright, a popup usually refers to a new browser page opened by an action such as clicking a link with target="_blank". Playwright also supports JavaScript dialogs such as alert(), confirm(), and prompt().

How to Handle a New Tab

The recommended approach is to start waiting for the popup before clicking the button that opens it:

const popupPromise = page.waitForEvent('popup');

await page.getByText('Open New Tab').click();

const popup = await popupPromise;

await popup.waitForLoadState('domcontentloaded');
console.log(await popup.title());

This helps prevent timing problems because Playwright captures the new page as soon as it opens.

How to Handle JavaScript Alerts

Playwright automatically dismisses JavaScript dialogs when no handler is registered. If you want to accept an alert or inspect its message, use a dialog handler:

page.on('dialog', async dialog => {
  console.log(dialog.message());
  await dialog.accept();
});

Important: A dialog handler must accept or dismiss the dialog. Otherwise, the action that triggered it can remain blocked.

A Useful Fact for Students

Playwright supports Chromium, Firefox, and WebKit, making it useful for learning cross-browser automation. Its official documentation also provides examples for JavaScript, Python, Java, and .NET, helping students practice with different programming languages.
