get_elements方法在找不到元素的时候，希望可以返回空列表以便做判断，目前直接抛异常了，用len()也不能处理

[ChenQ16]

感谢建议，修改了代码，支持返回 空 list()

import seldom


class BaiduTest(seldom.TestCase):

    def test_case(self):
        """a simple test case """
        self.open("https://www.baidu.com")
        ret = self.get_elements(id_="error")
        print("-->", ret)
