Question

我在硒和铬驱动程序的帮助下运行了我的Wicket项目的JUnit测试。

我们的网站使用manifest和all支持HTML5离线模式，我们也想测试它。

我们使用ChromeDriver：

Map<String, Object> chromeOptions = new HashMap<String, Object>();
chromeOptions.put("binary", binarylocation);
DesiredCapabilities capabilities = DesiredCapabilities.chrome();
capabilities.setCapability(ChromeOptions.CAPABILITY, chromeOptions);
capabilities.setCapability(CapabilityType.SUPPORTS_NETWORK_CONNECTION, true);
driver = new ChromeDriver(capabilities);

但不可思议的是，在我的测试过程中尝试这个时出现了错误：

((NetworkConnection) chromeDriver).setNetworkConnection(ConnectionType.NONE);

错误是：

关于这一点：https://bugs.chromium.org/p/chromedriver/issues/detail?id=984这个功能应该是可能的，但不知道怎么回事？

有人可以给我一个提示吗？

这似乎是用于移动仿真。我对此进行了测试并能够重现您的错误，然后通过启用移动仿真来修复它，即：

Map<String, String> mobileEmulation = new HashMap<String, String>();
mobileEmulation.put("deviceName", "Laptop with touch");

Map<String, Object> chromeOptions = new HashMap<String, Object>();
chromeOptions.put("mobileEmulation", mobileEmulation);
chromeOptions.put("binary", binarylocation);
DesiredCapabilities capabilities = DesiredCapabilities.chrome();
capabilities.setCapability(ChromeOptions.CAPABILITY, chromeOptions);
capabilities.setCapability(CapabilityType.SUPPORTS_NETWORK_CONNECTION, true);
driver = new ChromeDriver(capabilities);

我认为您可能只需要将网络类型设置为飞行模式，而不是无，但这不起作用（不启用移动仿真）。

错误＆＃34;必须启用网络连接＆＃34;使用ChromeDriver设置networkConnection
