public ShellStatusChecker ()

Public methods

postExecutionCheck

public StatusCheckerResult postExecutionCheck (ITestDevice device)

Check system condition after test module execution. Subclass should override this method if a check is desirable here. Implementation must return a boolean value to indicate if the status check has passed or failed.

Parameters
device ITestDevice: The ITestDevice on which to run the checks.

Returns
StatusCheckerResult result of system status check

Throws
DeviceNotAvailableException

preExecutionCheck

public StatusCheckerResult preExecutionCheck (ITestDevice device)

Check system condition before test module execution. Subclass should override this method if a check is desirable here. Implementation must return a boolean value to indicate if the status check has passed or failed.

It's strongly recommended that system status be checked after module execution, and this method may be used for the purpose of caching certain system state prior to module execution.

Parameters
device ITestDevice: The ITestDevice on which to run the checks.

Returns
StatusCheckerResult result of system status check

Throws
DeviceNotAvailableException
