Interacting with Web Elements in Playwright

Playwright provides several methods to interact with web elements. Let's explore some of them.

Clicking Buttons

To click a button, first locate it using the getByRole method. Then, call the click() method on it. Here's how you do it:

await page.getByRole('button').click();

This simulates a human click, triggering any associated events.

Typing into Input Fields

If you need to type into an input field, use the locator.type() method. This simulates a user typing on a real keyboard.

await page.locator('#area').type('Hello World!');

Other Mouse Actions

Playwright also lets you double-click, right-click, and hover over elements. Use the .dblclick(), .click({button: 'right'}), or .hover() methods respectively.

await page.getByRole('button').dblclick();
await page.getByRole('button').click({button: 'right'});
await page.getByRole('button').hover();

Forcing Clicks

Sometimes, hovering over an element overlays it with another one that intercepts clicks. In this case, you can force clicks by adding {force: true} to your click options.

await page.getByRole('button').click({ force: true });

Writing Tests

When writing tests, use web first assertions instead of manual ones. Web first assertions let Playwright wait until expected conditions are met before proceeding with test execution. This reduces the chances of flaky tests. For more on this, check out Mastering the Art of Detecting and Handling Flaky Tests in Playwright.
