装饰器 handle_black ,与自定义方法滚动查找 swipe_find 冲突,请问该如何改造

问题描述:

自定义的 handle_black 装饰器,导致自定义滚动查找 swipe_find 失效
装饰器导致无法进行到 swipe_find 的异常处理步骤
请问如何改造才能使 swipe_find 生效

详细代码:

find

@handle_black
    def find(self, by, locator=None) -> WebElement:
        if locator is None:
            result = self.driver.find_element(*by)
        else:
            result = self.driver.find_element(by, locator)

swipe_find

    def swipe_find(self, locator):
        self.driver.implicitly_wait(1)
        num = 5
        for i in range(0, num):
            if i == num - 1:
                raise NoSuchElementException(f"找了{i}次,未找到")
            try:
                element = self.find(locator)
                self.driver.implicitly_wait(5)
                return element
            except NoSuchElementException:
                print("未找到,滑动")
                size = self.driver.get_window_size()
                width = size["width"]
                height = size["height"]
                start_x = width / 2
                start_y = height * 0.8
                end_x = start_x
                end_y = height * 0.3
                duration = 2000
                self.driver.swipe(start_x, start_y, end_x, end_y, duration)```

是不是,元素虽然没出现在界面,但是元素已经加载到dom结构中,find已经找到这个元素了,所以失效了。

你直接find界面外的元素,看看报NoSuchElementException吗

是这样的,瓶子老师

元素没出现在界面(实际滚动界面能看到) → 进入黑名单查找 → 没找到,抛出 ValurEerror
这样就无法进入滑动查找的环节

我去掉装饰器是可以正常滑动查找的

代码贴到gitee上吧,然后报错截图出来
