public LogcatOnFailureCollector ()

public void onTestFail (DeviceMetricData testData, 
                TestDescription test)

Callback when a test case fails.

Parameters
`testData`	`DeviceMetricData`: the `DeviceMetricData` holding the data for the test case.
`test`	`TestDescription`: the `TestDescription` of the test case in progress.

public void onTestRunEnd (DeviceMetricData runData, 
                 currentRunMetrics)

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

Parameters
`runData`	`DeviceMetricData`: the `DeviceMetricData` holding the data for the run. Will be the same object as during `onTestRunStart(com.android.tradefed.device.metric.DeviceMetricData)`.
`currentRunMetrics`	: the current map of metrics passed to `ITestLifeCycleReceiver.testRunEnded(long, Map)`.

public void onTestRunFailed (DeviceMetricData testData, 
                FailureDescription failure)

Parameters
`testData`	`DeviceMetricData`
`failure`	`FailureDescription`

public void onTestRunStart (DeviceMetricData runData)

Callback when a test run is started.

Parameters
`runData`	`DeviceMetricData`: the `DeviceMetricData` holding the data for the run.

public void onTestStart (DeviceMetricData testData)

Callback when a test case is started.

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