playwright-python-`handleSIGTERM = False`导致UnhandledPromiseRejectionWarning并关闭浏览器

如何解决playwright-python-`handleSIGTERM = False`导致UnhandledPromiseRejectionWarning并关闭浏览器

我收到UnhandledPromiseRejectionWarning错误，并且在尝试模拟测试失败时不应关闭浏览器。

documentation说，我应该将 handleSIGTERM 设置为False，并且在运行结束时不应该关闭浏览器，对吗？所以我做到了（请参见代码示例）。

handleSIGTERM：可选[bool]在SIGTERM上关闭浏览器进程。默认为true。

Environment:
node v15.0.1
Python 3.8.0
MacOS Catalina 10.15.7 
playwright 0.152.0

代码示例：

import asyncio

from playwright import async_playwright


async def main():
    playwright = await async_playwright().start()
    browser = await playwright.chromium.launch(headless=False,handleSIGTERM=False,handleSIGHUP=False)
    page = await browser.newPage()
    page.setDefaultTimeout(timeout=5000)

    await page.goto('https://google.com/')

    # the following row simulates test failure
    await page.waitForSelector('input[name="q"]',state='hidden')

    await browser.close()
    await playwright.stop()


if __name__ == "__main__":
    asyncio.run(main())

意外的行为是浏览器关闭并且节点显示以下输出：

您知道我要怎么做吗？
