python+appium地区定位 20C

图片说明
是不是我没说清楚啊,要python自动化实现选择需要选择的地区,我在选择的时候只能选择整个大的框架,选择不到里面各个的省市区,有什么方法实现吗?我用了for循环选择一个地区,然后对这个框架的text对比,可是这个整个框架没有test。

正常地图定位应该是有插件,
如果你不用插件工具,那么你使用网络定位,
手机连网,用网络定位,一般移动或者一些大公司会有这样的接口报出,你可以搜搜看看

怎么选择指定的地区,不要坐标定位滑动。

找一个第三方植入比较准确。用大数据!

python+appium,sendkeys输入不了内容,无论中文还是数字怎么办?
sendkeys其他输入框都能输入,只有这个不能输入,能够定位到输入框,能看得见光标显示了,无论是ID定位还是xpath定位最多也只是显示光标,有过一次手动输入几个字符后成功的输入进去了。贴代码 ``` #输入手机号 account_name = driver.find_element_by_id('com.eestar:id/edtPhone').send_keys("15512341234") #输入验证码 password = driver.find_element_by_id('com.eestar:id/edtCode').send_keys("1111") #点击登录 driver.find_element_by_id("com.eestar:id/txtLogin").click() #点击首页唯一直播 driver.find_element_by_id("com.eestar:id/txtTitle").click() #输入聊天内容 time.sleep(5) #a = 123 driver.find_element_by_id("com.eestar:id/txtChat").send_keys("3369") ``` ![图片说明](https://img-ask.csdn.net/upload/201908/08/1565231480_994747.png) 光标能显示到输入框中,当时最终还是报错,只有这个一个输入框这样,是什么情况呢? python报错信息: ``` raise exception_class(message, screen, stacktrace) selenium.common.exceptions.NoSuchElementException: Message: UiSelector[INSTANCE=0, RESOURCE_ID=com.eestar:id/txtChat] ``` appium提示信息: ``` [AndroidBootstrap] [BOOTSTRAP LOG] [debug] Attempting to clear using UiObject.clearText().

cmd中可执行的命令,用python os.popen提示“不是内部或外部命令,也不是可运行的程序”
因工作需要研究 python + appium 自动化,从 github 下载了最新的 appium-desktop-setup-1.8.2.exe 安装并且配置好所有相关内容,在 cmd 命令行中输入“appium -a 127.0.0.1 -p 4723”,可以正确地开启 appium server 1.9.1 的服务。然而在 python 中, 执行这段代码 ``` import os os.popen('appium -a 127.0.0.1 -p 4723') ``` 却提示“'appium' 不是内部或外部命令,也不是可运行的程序” 但是同样的这段代码却又是可以执行的 ``` import os print(os.popen('netstat -aon | findstr 4723').readlines()) ``` 包括像 adb devices 这样的命令都可以,但是 appium 的就是不行。求解!

appium+python进行手机app自动化测试时遇到元素定位问题

Appium到底怎么定位父兄元素?
百度了很多次都说用当前元素(例如ele)的ele.find _ element _ by _ xpath ( ' // parent :: * ') 方法找父元素,用 preceding-sibling :: 找兄元素,following-sibling :: 找弟元素,但执行下来就是找不到元素,而实际上从 xml 可以明显看到存在 父/兄/弟 元素。尝试了各种方法很多天了,但是还是没办法实现 父/兄/弟 元素的定位,不知道是不是少了什么引用?还请高手指点。P.S.:找不到,但不报错。

Java学习的正确打开方式
在博主认为,对于入门级学习java的最佳学习方法莫过于视频+博客+书籍+总结,前三者博主将淋漓尽致地挥毫于这篇博客文章中,至于总结在于个人,实际上越到后面你会发现学习的最好方式就是阅读参考官方文档其次就是国内的书籍,博客次之,这又是一个层次了,这里暂时不提后面再谈。博主将为各位入门java保驾护航,各位只管冲鸭!!!上天是公平的,只要不辜负时间,时间自然不会辜负你。 何谓学习?博主所理解的学习,它是一个过程,是一个不断累积、不断沉淀、不断总结、善于传达自己的个人见解以及乐于分享的过程。
程序员必须掌握的核心算法有哪些?

程序员接私活怎样防止做完了不给钱?

【技巧总结】位运算装逼指南
位算法的效率有多快我就不说,不信你可以去用 10 亿个数据模拟一下,今天给大家讲一讲位运算的一些经典例子。不过,最重要的不是看懂了这些例子就好,而是要在以后多去运用位运算这些技巧,当然,采用位运算,也是可以装逼的,不信,你往下看。我会从最简单的讲起,一道比一道难度递增,不过居然是讲技巧,那么也不会太难,相信你分分钟看懂。 判断奇偶数 判断一个数是基于还是偶数,相信很多人都做过,一般的做法的代码如下...
为什么要学数据结构?
一、前言 在可视化化程序设计的今天,借助于集成开发环境可以很快地生成程序,程序设计不再是计算机专业人员的专利。很多人认为,只要掌握几种开发工具就可以成为编程高手,其实,这是一种误解。要想成为一个专业的开发人员,至少需要以下三个条件: 1) 能够熟练地选择和设计各种数据结构和算法 2) 至少要能够熟练地掌握一门程序设计语言 3) 熟知所涉及的相关应用领域的知识 其中,后两个条件比较容易实现,而第一个...
