滑屏找元素

在APP测试时，经常需要滑屏，才能找到元素。所以我们把滑屏找元素，然后再操作进行一次封装。

base_action.py中

def scroll_page_one_time(self, direction):

    screen_width = self.driver.get_window_size()["width"]
    screen_height = self.driver.get_window_size()["height"]
    center_x = screen_width * 0.5
    center_y = screen_height * 0.5
    down_x = center_x
    down_y = screen_height * 0.75
    up_x = center_x
    up_y = screen_height * 0.
    left_x = screen_width * 0.25
    left_y = center_y
    right_x = screen_width * 0.75
    right_y = center_y

    if direction == "up":
        self.driver.swipe(down_x, down_y, up_x, up_y, 3000)
    elif direction == "down":
        self.driver.swipe(up_x, up_y, down_x, down_y, 3000)
    elif direction == "left":
        self.driver.swipe(right_x, right_y, left_x, left_y, 3000)
    elif direction == "right":
        self.driver.swipe(left_x, left_y, right_x, right_y, 3000)
    else:
        raise Exception("您输入的参数有误，请检查，direction参数必须是up/down/left/right")
def is_loc_exist_scroll_page(self, loc, direction):
    page_source = ''
    while True:
        if self.driver.page_source == page_source:
            return False
        try:
            self.find_element(loc)
            return True
        except Exception:
            page_source = self.driver.page_source
            self.scroll_page_one_time(direction)
第一个方法是滑屏，第二个是看页面是否有元素，如果当前页面有，就返回True。否则继续滑，直到滑到页面的尽头
swipe_page.py中

#设置中的测试语言
def click_language(self):
    if self.is_loc_exist_scroll_page(self.language_btn, "up"):
        self.click(self.ram_btn)
    else:
        assert False

def click_yuyan(self):
    self.click(self.yuyan_btn)

def click_selected(self):
    ele_sel = self.is_loc_exist_scroll_page(self.selected_lan_btn, "up")
    self.click(self.selected_lan_btn)
test_swipe.py

def test_swipe_language(self):
    self.languageSwipe.click_language()
    self.languageSwipe.click_yuyan()
    self.languageSwipe.click_selected()

所有滑屏找元素都可以用这个模板。
