在Android設備上運行DumpRenderTree

Question

我一直在嘗試在Android（運行ICS的Android設備上）運行DumpRenderTree測試，但無法弄清楚如何運行它。很少有文檔和唯一的其他線程我發現（也就是接近我的問題）是這樣的：

How do you push Android Instrumentation Tests to Emulator/Device?

這裏是我的DDMS輸出，當我運行此命令：

在我運行這個之前，我應該推進一些測試嗎？任何指針將不勝感激！

顯示渲染樹的一個棘手方法是在股票android瀏覽器的URL欄中輸入about:debug.render.file。

然後你可以在/mnt/sdcard/renderTree.txt找到一個文件。

同樣，about:debug.dom.file導致DOM樹輸出。
