当我尝试运行我的代码却报出了协程页转到从未期待

我在使用playwright写自动化脚本的时候，使用类封装后尝试运行我的代码，然而确保协程页面转到从未期待

class MyTestCase():
    def __init__(self):
        with sync_playwright() as p:
            for browser_type in [p.chromium, p.firefox, p.webkit]:
                browser:Browser = browser_type.launch(headless=False)
                self.page:Page = browser.new_page()


class One(MyTestCase):
    def run(self):
        print(self.page)
        self.page.goto(url)

if __name__ == '__main__':
    m = One()
    m.run()
