使用Appium作app自动化测试，绕不开的就是下拉刷新操作，下拉是最常见的，其实还有上滑、左滑、右滑操作。在正式的测试流程里，可以把刷新操作封装成一个模块，需要时直接调用。
Appium中提供了三种滑动的方式：swipe滑动、scroll滑动、drag拖拽事件
swipe()方法是从⼀个坐标位置滑动到另⼀个坐标位置，是两个点之间的滑动。
def swipe(self, start_x, start_y, end_x, end_y, duration=None):
"""Swipe from one point to another point, for an optional duration.
:Args:
- start_x - x-coordinate at which to start
- start_y - y-coordinate at which to start
- end_x - x-coordinate at which to stop
- end_y - y-coordinate at which to stop
- duration - (optional) time to take the swipe, in ms.
:Usage:
driver.swipe(100, 100, 100, 400)
"""
# `swipe` is something like press-wait-move_to-release, which the server
# will translate into the correct action
action = TouchAction(self)
action
.press(x=start_x, y=start_y)
.wait(ms=duration)
.move_to(x=end_x, y=end_y)
.release()
action.perform()
return self
- start_x - 滑动开始x轴坐标
- start_y - 滑动开始y轴坐标
- end_x - 滑动结束x轴偏移量
- end_y - 滑动结束y轴偏移量
- duration - (可选) 执行此次滑动时间，单位毫秒
其中end_x 和 end_y 为基于start_x 和start_y 的偏移量；最终在执行中的 to_x = start_x +end_x 并非end_x ；duration 参数单位为ms（默认5毫秒），注意 1s = 1000ms。
封装刷新模块便于随时调用，我们可以自行封装代码，将上滑、下滑、左滑、右滑封装成一个刷新模块。

假设刷新模块的文件名为app_slide 那么可以这样调用
from app_slide import Slide #调用时传递appium.webdriver flush = Slide(driver) #下拉刷新 flush.swipe_down(1000)
