## API ##

提供同步(阻塞)API 和异步 API。它们在功能方面是相同的，并且仅在使用 API 的方式上有所不同。

from playwright import sync_playwright
    
    with sync_playwright() as p:
        for browser_type in [p.chromium, p.firefox, p.webkit]:
            browser = browser_type.launch()
            page = browser.newPage()
            page.goto('http://whatsmyuseragent.org/')
            page.screenshot(path=f'example-{browser_type.name}.png')
            browser.close()

async

import asyncio
    from playwright import async_playwright
    
    async def main():
        async with async_playwright() as p:
            for browser_type in [p.chromium, p.firefox, p.webkit]:
                browser = await browser_type.launch()
                page = await browser.newPage()
                await page.goto('http://whatsmyuseragent.org/')
                await page.screenshot(path=f'example-{browser_type.name}.png')
                await browser.close()
    
    asyncio.get_event_loop().run_until_complete(main())

## 自带pytest ##

def test_playwright_is_visible_on_google(page):
        page.goto("https://www.google.com")
        page.type("input[name=q]", "Playwright GitHub")
        page.click("input[type=submit]")
        page.waitForSelector("text=microsoft/Playwright")
