    根据报错信息显示，问题出在 capture_screenshots 函数中，报错提示 NameError: name 'page' is not defined，即没有定义变量 page。

    这是因为在 capture_screenshots 函数中，使用了全局变量 page，但是在函数内部并没有直接引用该变量，导致 Python 报错未定义。解决方法是在函数内部添加 global page，以便在函数内部能够访问到该全局变量。修改后的函数如下所示：

    def capture_screenshots(failed_case):
    """
    配置用例失败截图路径
    :return:
    """
    global page  # 添加全局变量声明
    logging.error(f'测试用例执行失败，测试用例描述为===========>{failed_case}')
    if CONFIG.REPORT_PATH is None:
        raise NameError('没有初始化测试报告目录')
    else:
        img_bytes = page.screenshot()
        return str(base64.b64encode(img_bytes), 'utf-8')

    通过添加 global page 声明，可以解决该报错问题。请尝试修改后重新运行代码，看是否问题得到解决。

    如果该回答解决了您的问题，请采纳一下，谢谢!
