摘要
公共构造函数
DeviceSettingChecker
public DeviceSettingChecker ()
公共方法
postExecutionCheck
public StatusCheckerResult postExecutionCheck (ITestDevice device)
检查测试模块执行后的系统状态。如果需要在此处进行检查，子类应替换此方法。实现必须返回 boolean 值，以指明状态检查是否已通过或失败。
preExecutionCheck
public StatusCheckerResult preExecutionCheck (ITestDevice device)
在执行测试模块之前检查系统状态。如果需要在此处进行检查，子类应替换此方法。实现必须返回 boolean 值，以指明状态检查是否已通过或失败。
强烈建议在模块执行之后检查系统状态，并且此方法可用于在模块执行之前缓存特定系统状态。
