捕获所有屏幕的布局 - Android App

Question

我想测试 android 应用程序是否存在可访问性违规。是否可以使用 uiautomator api 和 monkeyrunner api 来捕获所有屏幕的布局？

Answer 1

您可以简单地使用 AndroidViewClient 的转储：

$ dump --help
usage: dump [OPTION]... [serialno]

Options:
  -H, --help                       prints this help                             
  -V, --verbose                    verbose comments                             
  -v, --version
  -I, --ignore-secure-device       ignore secure device                         
  -E, --ignore-version-check       ignores ADB version check                    
  -F, --force-view-server-use      force view server use (even if UiAutomator present)
  -S, --do-not-start-view-server   don't start ViewServer                       
  -k, --do-not-ignore-uiautomator-killed don't ignore UiAutomator killed              
  -w, --window=WINDOW              dump WINDOW content (default: -1, all windows)
  -i, --uniqueId                   dump View unique IDs                         
  -x, --position                   dump View positions                          
  -d, --content-description        dump View content descriptions               
  -c, --center                     dump View centers                            
  -f, --save-screenshot=FILE       save screenshot to file                      
  -W, --save-view-screenshots=DIR  save View screenshots to files in directory  
  -D, --do-not-dump-views          don't dump views, only useful if you specified -f or -W

在你的情况下，可能

$ dump -d

够了。

如果您想要的不仅仅是保存屏幕的逻辑内容更复杂，您可以使用culebra（AndroidViewClient 中的另一个工具），它允许您使用 GUI 生成自动化测试：

$ culebra -UG -o mytest.py

您可以与 culebra 主窗口中设备屏幕的镜像表示进行交互以生成测试。保存。在任何设备上运行它，甚至是完全不同的设备。
