我在进行仪器测试时使用了Robotium。大部分情况下，我可以测试一切，但是离线情况除外。
只要我禁用数据（使用adb、模拟器中的F8快捷键等...），测试就会断开连接。它在设备/模拟器中继续运行，但没有结果报告。
所以，我想到了一个想法，只将应用程序置于脱机模式，而不是整个设备。问题是我不知道怎么做...
使用iptablesApi需要对我的设备进行root。我已经阅读过Mobiwol应用程序使用某种VPN来限制应用程序的互联网访问，而无需对设备进行root。
问题 Mobiwol应用程序如何按应用程序阻止互联网连接？或者还有其他方法来离线测试APK吗？

我忘了说，我能够在离线状态下运行测试，但必须在设备处于离线状态时启动测试。目前，我将我的测试分为离线和联机两个部分。在运行ONLINEs之后，我执行著名的adb kill-server和adb start-server。然后我执行OFFLINEs。
由于这里似乎有不同的问题，我只是提出一些建议。 1）如果您只想在运行离线测试用例之前关闭数据，则可以尝试使用Robotium本身来实现。
例如： 对于WiFi：
WifiManager wifi=(WifiManager)solo.getCurrentActivity().getSystemService(Context.WIFI_SERVICE);
wifi.setWifiEnabled(false);
移动数据（使用反射）：
ConnectivityManager dataManager=(ConnectivityManager)solo.getCurrentActivity().getSystemService(Context.CONNECTIVITY_SERVICE);
Method dataClass = ConnectivityManager.class.getDeclaredMethod(“setMobileDataEnabled”, boolean.class);
dataClass.setAccessible(true);
dataClass.invoke(dataManager, true);
setup() 方法运行单个测试用例之前执行上述两个调用。当 OFFLINE 测试套件中的所有测试用例都完成后，可以在 teardown() 方法的最后启用 WiFi/DATA。根据操作系统版本使用 ipTables
创建一个脚本标头，基于需要 WiFi/Data 的所有应用程序的 UID
应该从包管理器中获取设备上安装的应用程序列表以及任何隐藏应用程序等。
再次根据用户选择执行脚本并使用用户所需的规则覆盖 ipTable 中的现有规则。
在尝试了类似于user2511882的解决方案数小时后，我仍然遇到了一个异常，因为缺少权限（是的，“修改系统设置”权限已经被激活）。
最终我使用UI automator完成了它：
public static void setAirplaneMode(boolean enable)
{
if ((enable ? 1 : 0) == Settings.System.getInt(getInstrumentation().getContext().getContentResolver(),
Settings.Global.AIRPLANE_MODE_ON, 0))
{
return;
}
UiDevice device = UiDevice.getInstance(getInstrumentation());
device.openQuickSettings();
// Find the text of your language
BySelector description = By.desc("Airplane mode");
// Need to wait for the button, as the opening of quick settings is animated.
device.wait(Until.hasObject(description), 500);
device.findObject(description).click();
getInstrumentation().getContext().sendBroadcast(new Intent(Intent.ACTION_CLOSE_SYSTEM_DIALOGS));
}
您需要在 androidTest 清单文件中添加 ACCESS_NETWORK_STATE：
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
测试结束后不要忘记禁用它。
如果您使用的语言不是英语，则需要将“飞行模式”更改为您所使用的语言的文本。由于我有多种翻译，因此我从资源字符串中读取它。
Thread.sleep 就可以让测试通过了。 - pavi2410LinkedIn的Test Butler有一个非常好用的库，你只需调用以下代码即可轻松启用或禁用WiFi和移动数据:
TestButler.setGsmState(false);
TestButler.setWifiState(false);
这里有一个解决方案，它使用UiAutomator来从下拉状态栏启用或禁用“飞行模式”，如果启用，则关闭所有网络连接。它适用于大多数Android操作系统版本，并使用了用户Aorlinn（2019年10月12日）的答案的部分内容。
dependencies {
androidTestImplementation "androidx.test.uiautomator:uiautomator:2.2.0"
}
不需要额外的权限，甚至不需要 <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> 因为UiAutomator仅在状态栏UI上点击按钮。因此，应用程序不需要直接访问修改设备的Wifi或移动数据设置。

如果您的设备语言不是英语，您将需要调整字符串"Aeroplane mode"。例如，您可以在此处检查大约70种语言的翻译：https://github.com/aosp-mirror/platform_frameworks_base/search?q=global_actions_toggle_airplane_mode
ACCESS_NETWORK_STATE并使用Aorlinn的解决方案通过Settings.System在程序中进行编程检查，而不是尝试解析shell命令的输出。 - Adam BurleygetCurrentAirplaneModeSetting()函数中，我同时使用了Settings.System.getInt()和executeShellCommand()来获取当前的飞行模式设置。之所以使用了两种不同的策略，是因为其中一种方法在所有的Android操作系统版本上都不起作用。 - undefinedInstrumentationRegistry.getInstrumentation().getUiAutomation().executeShellCommand("svc wifi disable")
InstrumentationRegistry.getInstrumentation().getUiAutomation().executeShellCommand("svc data disable")
