Using CSS/XPath Selectors in Playwright

Playwright is a powerful end-to-end testing framework that enables automation across browsers like Chrome, Firefox, and Safari. One of the most crucial parts of writing reliable Playwright tests is selecting the right elements. Playwright supports both CSS selectors and XPath selectors, each offering unique advantages.

CSS Selectors are concise and widely used. They allow you to locate elements by ID, class, attributes, hierarchy, and pseudo-classes. For example:

await page.click('button.submit');  

await page.fill('#username', 'testuser');

CSS is often the first choice due to simplicity, speed, and readability.

XPath Selectors, on the other hand, are more powerful when working with complex DOM structures. They can navigate both forward and backward in the hierarchy, making them suitable for dynamic or deeply nested elements. Example:

await page.click('//button[text()="Login"]');

XPath is flexible but can be harder to maintain because expressions are typically longer.

Best Practices:

Prefer CSS selectors for readability and performance.

Use XPath when you need to target elements by text or traverse up the DOM.

Keep selectors stable by avoiding auto-generated attributes.

Leverage Playwright’s built-in selector engines like text= or role= for improved test reliability.

By mastering CSS and XPath selectors, you can build more robust Playwright tests that adapt to real-world web applications.
