# Browser Automation Automate browser tasks for scraping, testing, and workflows. ## Core capabilities - **Navigation**: load URLs, wait for selectors, scroll, handle navigation. - **Interaction**: click, type, select, upload files. - **Extraction**: read text, attributes, tables, or lists. - **Capture**: screenshots, PDFs, and traces. ## Workflow 1. Open the page. 2. Wait for the right selector. 3. Interact with elements. 4. Extract or capture the result. 5. Handle pagination or repeated steps with clear bounds. ## Best practices - Use stable selectors like `data-testid` instead of CSS paths. - Wait for elements before interacting. - Add human-like delays when mimicking real users. - Respect rate limits and robots.txt. - Capture screenshots on failure. - Use headless mode for production. ## Example ```javascript await page.goto('https://example.com/login'); await page.fill('#email', 'user@example.com'); await page.fill('#password', 'securepass'); await page.click('button[type="submit"]'); await page.waitForNavigation(); ``` ## Guardrails - Do not scrape behind authentication unless explicitly asked. - Do not run aggressive crawlers without rate limiting. - Keep personal data out of logs and screenshots.
