自动化测试 智能等待 解决元素操作不稳定问题

# 判断元素是否存在
def isElementExist(driver, element_xpath):
    flag = True
    try:
        driver.find_element_by_xpath(element_xpath)
        print("Good~找到了元素："+element_xpath)
        return flag
    except:
        flag = False
        print("≧ ﹏ ≦未找到元素：" + element_xpath)
        return flag

# 智能等待

    # 循环18次 每次等1秒
    for i in range(18):
        if i >= 17:
            print("smart_wait time out" + str(i))
            break
        else:
            try:
                # 如果找到元素就返回元素，然后break
                if isElementExist(driver, element_xpath) is True:
