playwright

Browser automation with Playwright.

Installation

npm init playwright@latest npx playwright install chromium

Core concepts

• Browser: Chrome, Firefox, Safari
• Context: isolated browser session
• Page: single tab
• Locator: find elements (page.locator())
• Assertion: verify state (expect())

Common patterns

• Navigate: page.goto(url)
• Click: page.click(selector)
• Type: page.fill(selector, text)
• Wait: page.waitForSelector(selector)
• Screenshot: page.screenshot()
• Evaluate: page.evaluate(js)

Best practices

• Use locators over XPath/CSS when possible
• Test user flows, not implementation
• Parallel test execution
• Screenshot on failure
• Use fixtures for test data
• Mock network requests for reliability
