Public methods

onTestEnd

public void onTestEnd (DeviceMetricData testData, 
                 currentTestCaseMetrics, 
                TestDescription test)

Callback when a test case is ended. This should be the time for clean up.

Parameters
testData	DeviceMetricData: the DeviceMetricData holding the data for the test case. Will be the same object as during onTestStart(com.android.tradefed.device.metric.DeviceMetricData).
currentTestCaseMetrics	: the current map of metrics passed to ERROR(/#testEnded(com.android.tradefed.result.TestDescription,Map)).
test	TestDescription: the TestDescription of the test case in progress.

Throws
DeviceNotAvailableException

onTestStart

public void onTestStart (DeviceMetricData testData)

Callback when a test case is started.

Parameters
testData	DeviceMetricData: the DeviceMetricData holding the data for the test case.

Throws
