Then, click on the Toggle Device Toolbar.Ĭlick on the dropdown - Responsive to get the list of devices. Right-click on a page opened in the Chrome browser, then select Inspect. The list of devices that the Puppeteer supports can be obtained from the Chrome DevTools. We can run tests with mobile configurations in Puppeteer and check the responsive property of a webpage.
