您好我正在尝试使用 iPhone 模拟器和 Android 模拟器在 Mac 服务器上设置 Selenium GRID II。我可以将 iPhone 连接到 Grid，甚至可以开始测试。但是在连接 Android Emulator 时出现以下错误。

我在做什么？

1.) 我在 Android 上安装 android-standalone-server.apk 并使用 adb 将端口 8080 转发到 8080。

2.）然后开始连接到网格的新节点，如下所示

java -jar selenium-server-standalone-2.25.0.jar -role node -hub http://localhost:4444/grid/register -port 8080 -browser browserName="Android",version="4",platform="MAC"

我在做什么错？

2 things to try.

1: try running the node launch command with this updated syntax: java -jar selenium-server-standalone.jar -role node -hub http://localhost:4444/grid/register -port 8080 -browser "browserName=android,version=4,platform=MAC"

2: follow the updated instructions here:

我终于能够进行 Android 测试。我按照https://code.google.com/p/selenium/wiki/AndroidDriver上的详细说明进行操作

不要启动本地节点来连接到您的集线器。相反，在您的 Android 设备上启动 WebDriver 后，使用adb -s {id} forward tcp:8080 tcp:8080命令转发端口。这就对了。您已准备好进行测试。您已将测试修改为现在连接到您正在转发的端口。

我使用 selenium 网格，所以在执行 android 测试时我必须修改我的测试以适应不同的集线器。我无法连接到 selenium 集线器，而是必须直接连接到 android 设备，就好像它是集线器一样。我找不到将 android 设备注册为我使用的主要 selenium 集线器的节点的方法。

在您的 android 测试中，您需要http://localhost:8080/wd/hub在创建 RemoteWebDriver 时连接到。这会将您连接到 android 设备上的集线器，您的测试将从那里开始。

希望有一种方法可以在 android 设备上配置 WebDriver 以注册为具有现有集线器的节点。我确定有，但我还没有弄清楚。
