一、前置说明
Appium 原生的swipe()方法，需要指定起始坐标点的位置，方法调用偏底层。我们可以使用get_window_size()获取窗口大小，然后按比例定义起始位置，从而实现上下左右的滑动。
二、代码实现
from appium.webdriver.webdriver import WebDriver as Remote
from appium.options.android import UiAutomator2Options
from libs.check import CommonChecker
from libs.decorators import rerun_if_exception
class WebDriver(Remote):
def __init__(self, command_executor, capabilities: dict, *args, **kwargs):
# solve the problem: AttributeError: NoneType' object has no attribute 'to_capabilities'.
# https://stackoverflow.com/questions/77118636/attributeerror-nonetype-object-has-no-attribute-to-capabilities-getting-th
options = UiAutomator2Options().load_capabilities(capabilities)
super().__init__(command_executor=command_executor, options=options, *args, **kwargs)
def swipe_up(self, duration=500, num=1):
size = self.get_window_size()
x1 = size['width'] * 0.5
y1 = size['height'] * 0.75
y2 = size['height'] * 0.25
for i in range(num):
self.swipe(x1, y1, x1, y2, duration)
def swipe_down(self, duration=500, num=1):
size = self.get_window_size()
x1 = size['width'] * 0.5
y1 = size['height'] * 0.25
y2 = size['height'] * 0.75
for i in range(num):
self.swipe(x1, y1, x1, y2, duration)
def swip_left(self, duration=500, num=1):
size = self.get_window_size()
x1 = size['width'] * 0.75
y1 = size['height'] * 0.5
x2 = size['width'] * 0.05
for i in range(num):
self.swipe(x1, y1, x2, y1, duration)
def swip_right(self, duration=500, num=1):
size = self.get_window_size()
x1 = size['width'] * 0.05
y1 = size['height'] * 0.5
x2 = size['width'] * 0.75
for i in range(num):
self.swipe(x1, y1, x2, y1, duration)
@rerun_if_exception()
def swipe_to(self, direction, duration=500, num=1):
allowed = ['up', 'down', 'left', 'right']
CommonChecker.check_item_in_list(direction, allowed, 'direction')
if direction == 'up':
self.swipe_up(duration, num)
if direction == 'down':
self.swipe_down(duration, num)
if direction == 'left':
self.swip_left(duration, num)
if direction == 'right':
self.swip_right(duration, num)
在滑动页面时，可能会遇到页面未加载完成，从而导致滑动失败的问题。因此，在swipe_to() 方法上加了一个rerun_if_exception()失败重试的装饰器，相当于加了一个自动等待页面加载完成的功能。
三、Demo验证
测试代码：
def test_swipe_to():
from driver.appium.driver import WebDriver
appium_server_url = 'http://localhost:4723'
capabilities = {
"platformName": "Android",
"automationName": "uiautomator2",
"deviceName": "127.0.0.1:62001",
"app": "D:\\resources\\imooc.apk",
}
driver = WebDriver(command_executor=appium_server_url, capabilities=capabilities)
driver.swipe_to('left', num=2)
driver.swipe_to('right', num=2)
成功实现了滑动的效果，控制台运行结果：
