摘要
公用建構函式
SystemServerFileDescriptorChecker
public SystemServerFileDescriptorChecker ()
公用方法
postExecutionCheck
public StatusCheckerResult postExecutionCheck (ITestDevice device)
在執行測試模組後檢查系統狀態。如果需要在此處進行檢查，子類別應覆寫此方法。實作項目必須傳回 boolean 值，指出狀態檢查是否已通過或失敗。
preExecutionCheck
public StatusCheckerResult preExecutionCheck (ITestDevice device)
在執行測試模組前，請先檢查系統狀態。如果需要在此處進行檢查，子類別應覆寫此方法。實作項目必須傳回 boolean 值，指出狀態檢查是否已通過或失敗。
強烈建議您在模組執行後檢查系統狀態，並在模組執行前使用此方法快取特定系統狀態。
