无法在iOS设备上运行Xamarin应用的Calabash测试

Question

我们无法在真实的iPhone上运行部署在Xamarin应用上的Calabash测试。我们已经尝试从以下网址下载示例应用程序：http://developer.xamarin.com/guides/testcloud/calabash/introduction-to-calabash/。当部署到模拟器时可以运行，但是在尝试运行在真实设备上时则无法成功。我们可以在设备上安装和运行该应用程序，但是无法将其与Calabash配合使用。我们尝试运行的命令为：

APP_BUNDLE_PATH=~/Path/to/CreditCardValidation-Calabash/CreditCardValidation.iOS/bin/iPhone/Debug/CreditCardValidationiOS-1.0.ipa DEBUG=1 BUNDLE_ID=com.xamarin.calabash.example.creditcardvalidation DEVICE_TARGET=uuid-of-device DEVICE_ENDPOINT=http://ip.of.phone:37265 RESET_BETWEEN_SCENARIOS=1 cucumber

上述代码的输出为：

Running `curl http://ip.of.phone:37265/version` returns the expected json.

Answer 1

请确认以下内容：

1. 通过 USB 连接设备。
2. 确保捆绑标识符与应用程序的捆绑标识符匹配。
3. 设备是否出现在 xcrun instruments -s devices 的输出中？如果没有，请检查 Xcode 的设备窗口（Command + Shift + 2）。确保设备已列出并且没有警告出现。如果有错误出现，则退出Xcode，重新启动设备，再次启动Xcode。反复尝试直到错误消除。有时我必须将我的设备连接到另一台机器上才能消除警告。
4. 应用程序是否已安装在设备上？Calabash 无法在物理设备上安装应用程序。请参见 this project，了解如何使用ideviceinstaller作为Calabash测试的一部分安装应用程序。 我已添加TODO以改进该项目的README.md。

APP_BUNDLE_PATH=~/Path/to/CreditCardValidation-Calabash/CreditCardValidation.iOS/bin/iPhone/Debug/CreditCardValidationiOS-1.0.ipa

APP (首选)和 APP_BUNDLE_PATH 环境变量仅在针对模拟器时使用，当针对实际设备时，它们会被忽略。
