目前 playwright- Python 还是不完善

今天发现一个 BUG ，主要是开启调试的情况下，运行完会导致浏览器 crash ，插件全部 crash （和插件本身无关），相关 issue： https://github.com/microsoft/playwright-python/issues/2160

我这边目前 100%复现，代码很简单，我贴一个，有兴趣的可以复现一下。

playwright 代码

from playwright.sync_api import Playwright, sync_playwright, expect


def run(playwright: Playwright) -> None:
    browser = playwright.chromium.connect_over_cdp('http://127.0.0.1:2333')
    context = browser.contexts[0]
    # context.tracing.start(screenshots=True, snapshots=True, sources=True)
    page = context.pages[0]

    page.goto("https://www.baidu.com/")

    # context.tracing.stop(path = "trace.zip")
    # page.close()  # 加上 page.close()可以解决，但是会关闭网页啊，这没法继续后面的操作了。
    # context.close()
    # browser.close()



with sync_playwright() as playwright:
    run(playwright)

selenium 代码

from selenium import webdriver
from selenium.webdriver.chrome.service import Service
from selenium.webdriver.chrome.options import Options

chrome_service = Service('./chromedriver.exe')
chrome_options = Options()
chrome_options.add_experimental_option("debuggerAddress", "127.0.0.1:2333")

driver = webdriver.Chrome(service=chrome_service, options=chrome_options)
driver.get('https://www.baidu.com/')

今天发现 playwright 有头定位元素是根据前端视窗定位的？而不是根据前端源码？当我定位某个页面元素时，虽然它存在于前端源码中，但在当前分辨率下并没有出现在屏幕上，比如说有一个水平的滑动窗口，可以通过向左和向右的按钮来控制窗口中显示不同的内容，当前没有显示的话，这种情况下定位会导致视口上下晃动，直到发生 timeout 错误。
