const page = await browser.newPage();
// Navigate the page to a URL.
await page.goto('https://developer.chrome.com/');
// Set screen size.
await page.setViewport({width: 1080, height: 1024});
// Type into search box.
await page.locator('.devsite-search-field').fill('automate beyond recorder');
// Wait and click on first result.
await page.locator('.devsite-result-item-link').click();
// Locate the full title with a unique string.
const textSelector = await page
.locator('text/Customize and automate')
.waitHandle();
const fullTitle = await textSelector?.evaluate(el => el.textContent);
