我正在使用appium python-client库在iOS和Android设备上运行[py.]test.我注意到许多iOS测试都因点击点崩溃而不在屏幕范围内.由于提供的坐标似乎在设备显示的报告范围内,因此对测试进行调查似乎很奇怪.
以下代码段说明了我的问题：
from appium.webdriver.common.touch_action import TouchAction
def test_max_screen_size(appium_driver):
driver = appium_driver
window_size = driver.get_window_size()
max_width = window_size["width"] - 1
max_height = window_size["height"] - 1
action = TouchAction(driver)
action.tap(None, max_width, max_height).perform()
在这里,我尝试点击显示的最极端.
此测试在Android设备上通过,但在iOS模拟器设备上未通过(我尚未测试真正的iOS设备-但我敢肯定它也会崩溃).
这是一个Appium错误还是我做错了什么？
我的环境：
鸦片1.3.4
iOS 8.1current Appium Python client
Python 2.7.6
更新资料
我在这个问题上花了更多时间.
首先,我通过Instruments运行了这个简单的UIAutomation脚本：
var target = UIATarget.localTarget();
var max_width = target.rect().size.width;
var max_height = target.rect().size.height
UIALogger.logMessage("width: " + max_width + " height:" + max_height);
target.tap({x:max_width, y:max_height});
当您在iPhone 4s上运行此程序时,您将获得max_width = 320和max_height = 480,因为它是2x retina display-正是Appium告诉我们的以及期望的结果.
如果您增加了两个变量,则脚本将按预期方式失败,并出现以下情况：脚本引发了未捕获的JavaScript错误：点击点不在“新脚本”第8行的屏幕范围内.
这意味着Appium必须发送乐器不喜欢的东西.
因此,下一个故障点可能是appium python客户端.我使用pdb转到客户端与appium服务器对话的位置：
../remote_connection.py(349)execute()
-> return self._request(command_info[0], url, body=data)
(Pdb) l
344 command_info = self._commands[command]
345 assert command_info is not None, 'Unrecognised command %s' % command
346 data = utils.dump_json(params)
347 path = string.Template(command_info[1]).substitute(params)
348 url = '%s%s' % (self._url, path)
349 -> return self._request(command_info[0], url, body=data)
350
351 def _request(self, method, url, body=None):
352 """
353 Send an HTTP request to the remote server.
354
(Pdb) url
u'http://127.0.0.1:4723/wd/hub/session/c9e49cb0-d291-4fb5-8aef-d89b9ceaa759/touch/perform'
(Pdb) data
'{"sessionId": "c9e49cb0-d291-4fb5-8aef-d89b9ceaa759",
"actions": [{"action": "tap", "options": {"y": 479, "x": 319, "count": 1}}]}'
这表明appium python客户端似乎也正在按照您的期望进行操作.
这使Appium服务器成为下一故障点…
解决方法:
好吧,经过一会儿的挖掘,我终于找到了答案.与可以在屏幕上进行相对于全屏的任意点击的Instruments不同,Appium选择将您限制在应用程序的范围之内.这意味着,如果显示菜单栏,它将通过菜单栏的高度减小您的可点击区域.
您可以在appium服务器日志中看到以下内容：

在第2行中,您可以看到服务器如何响应设备分辨率.
在第14行中,您可以看到应用程序分辨率：320×460,在下面的行中,您可以看到我(现在是相对的)单击的实际位置：{“ x”：0.996875,“ y”：1.041304347826087}.
这是意外的,我希望API说明能够指出这一点-Appium中的选项卡是相对于应用程序窗口(而不是整个显示窗口)执行的.
长话短说
我现在必须使用< driver> .find_element_by_xpath(‘// UIAApplication [1]’).size替换iOS的< driver> .get_window_size().
