Appium 1.5.3 使用遇到的两个问题

adfghzhang · 2016年08月08日 · 最后由 测试老菜 回复于 2016年11月01日 · 2349 次阅读

环境：

  • CentOS 7.2
  • Appium 1.5.3

问题 1：

使用 driver.findElementByAccessibilityId("退出登录") 查找不到该元素，实际页面已经切到对应页面 且该按钮已经出现。请使用过 1.5.x 的同学分享一下经验，谢谢！

问题 2：

Hybrid 应用，切换到 WEBVIEW 时遇到问题，能正常打印出 contexts，但切换到 WEBVIEW 时抛异常 no such session。

public void toWeb() {
    List<String> handleList = new ArrayList<String>();
    Set<String> set = driver.getContextHandles();
    Iterator<String> it = set.iterator();
    while (it.hasNext()) {
        handleList.add(it.next());
    }
    try {
        driver.context(handleList.get(1));
    } catch (Exception e) {
        // TODO: handle exception
        e.printStackTrace();
    }
}

运行异常信息：

no such session 这个感觉么啥问题啊

淽沐 #2 · 2016年08月09日

1.5.3 版本，driver.findElementByAccessibilityId("退出登录") 这个方法是真对 web 元素来使用的，而且对应的是 content-desc

adfghzhang #3 · 2016年08月09日 Author

#2 楼 @chungeguo 针对 native 元素 text 属性现在能用什么方法来找元素呢

淽沐 #4 · 2016年08月09日

self.driver.find_element_by_android_uiautomator('text("我知道啦")').click()

淽沐 #5 · 2016年08月09日

而且真对 Hybrid 应用，现在不用切换 webview 啦

adfghzhang #6 · 2016年08月09日 Author

#5 楼 @chungeguo 刚刚试验了一下不切 web 连 chromedriver 都不会起，难道 python 跟 java 不一样？

淽沐 #7 · 2016年08月09日

#6 楼 @adfghzhang 我是 python，没有切换

张可 #8 · 2016年08月09日

想问下 centos 下怎么安装安卓 sdk..

adfghzhang #9 · 2016年08月09日 Author

#8 楼 @kesha0 我用纯命令行安装的，保证 sdk 安装上比较容易，但是 aapt 要需要 libc++ 就需要自己去编译。先下载 linux 版的 sdk 解压，然后到 tools 目录执行该命令安装 sdk 中的 build-tools,platform-tools,tools。中间如果提示差什么就安装什么

./android update sdk -u -t 1,2,3
adfghzhang #10 · 2016年08月09日 Author

#1 楼 @lihuazhang 替换了一个低版本的 chromedriver，执行就没有问题了，这好诡异。

恒温 #11 · 2016年08月09日

#2 楼 @chungeguo 不用切 context 了啊？

淽沐 #12 · 2016年08月09日

#11 楼 @lihuazhang 我是一直都没有切换过，python 版本的 ios，android，都不切换

adfghzhang #13 · 2016年08月09日 Author

#11 楼 @lihuazhang java 还得切，不然没反应 chromedriver 都不启动

panda #14 · 2016年08月12日

#12 楼 @chungeguo 设置这个 desired_caps["autoWebview"] = True 就不用在代码里面切换了吗？是 Appium 1.5.3 还是 Appium 1.4 的版本呀？

问题 2 我也遇到了，在 4.4 系统上面不会有问题，在 5.1 系统上面，切换到 WEBVIEW 时遇到问题，能正常打印出 contexts，但切换到 WEBVIEW 时抛异常 no such session。

pcc426 #16 · 2016年10月11日

#15 楼 @lirenjun_2016 同遇到此问题，搞了 2 天了，求解答😥

adfghzhang #17 · 2016年10月11日 Author

#16 楼 @pcc426 可以试试切换 WEBVIEW 之前可以先杀掉 chromedriver 进程

大浪 #18 · 2016年10月11日

#17 楼 @adfghzhang 怎么杀掉 chromedriver 进程？

adfghzhang #19 · 2016年10月12日 Author

#18 楼 @jira win 下可以用这个命令 cmd.exe /C start wmic process where name='chromedriver.exe' call terminate 其实这个百度一下就有很多种方法的

测试老菜 #20 · 2016年11月01日

我也遇到这个问题了，appium 版本 1.4.x，切换到 WEBVIEW，findELement 的方法就找不到元素，不切换反而可以
