ShardListener

public class ShardListener
extends CollectingTestListener

java.lang.Object
   ↳ com.android.tradefed.result.CollectingTestListener
     ↳ com.android.tradefed.invoker.ShardListener


A ITestInvocationListener that collects results from a invocation shard (aka an invocation split to run on multiple resources in parallel), and forwards them to another listener.

Summary

Public constructors

ShardListener(ITestInvocationListener master)

Create a ShardListener.

Public methods

void invocationEnded(long elapsedTime)

Reports that the invocation has terminated, whether successfully or due to some error condition.

void invocationFailed(Throwable cause)

Reports an incomplete invocation due to some error condition.

void invocationStarted(IInvocationContext context)

Reports the start of the test invocation.

void testLog(String dataName, LogDataType dataType, InputStreamSource dataStream)

Provides the associated log or debug data from the test invocation.

void testLogSaved(String dataName, LogDataType dataType, InputStreamSource dataStream, LogFile logFile)

Called when the test log is saved.

void testRunEnded(long elapsedTime, HashMap<String, MetricMeasurement.Metric> runMetrics)

Reports end of test run.

void testRunFailed(String failureMessage)

Reports test run failed to complete due to a fatal error.

Public constructors

ShardListener

public ShardListener (ITestInvocationListener master)

Create a ShardListener.

Parameters
master ITestInvocationListener: the ITestInvocationListener the results should be forwarded. To prevent collisions with other ShardListeners, this object will synchronize on master when forwarding results. And results will only be sent once the invocation shard completes.

Public methods

invocationEnded

public void invocationEnded (long elapsedTime)

Reports that the invocation has terminated, whether successfully or due to some error condition.

Will be automatically called by the TradeFederation framework.

Parameters
elapsedTime long: the elapsed time of the invocation in ms

invocationFailed

public void invocationFailed (Throwable cause)

Reports an incomplete invocation due to some error condition.

Will be automatically called by the TradeFederation framework.

Parameters
cause Throwable: the Throwable cause of the failure

invocationStarted

public void invocationStarted (IInvocationContext context)

Reports the start of the test invocation.

Will be automatically called by the TradeFederation framework. Reporters need to override this method to support multiple devices reporting.

Parameters
context IInvocationContext: information about the invocation

testLog

public void testLog (String dataName, 
                LogDataType dataType, 
                InputStreamSource dataStream)

Provides the associated log or debug data from the test invocation.

Must be called before ITestInvocationListener.invocationFailed(Throwable) or ITestInvocationListener.invocationEnded(long)

The TradeFederation framework will automatically call this method, providing the host log and if applicable, the device logcat.

Parameters
dataName String: a String descriptive name of the data. e.g. "device_logcat". Note dataName may not be unique per invocation. ie implementers must be able to handle multiple calls with same dataName

dataType LogDataType: the LogDataType of the data

dataStream InputStreamSource: the InputStreamSource of the data. Implementers should call createInputStream to start reading the data, and ensure to close the resulting InputStream when complete. Callers should ensure the source of the data remains present and accessible until the testLog method completes.

testLogSaved

public void testLogSaved (String dataName, 
                LogDataType dataType, 
                InputStreamSource dataStream, 
                LogFile logFile)

Called when the test log is saved.

Should be used in place of ITestLogger.testLog(String, LogDataType, InputStreamSource).

Parameters
dataName String: a String descriptive name of the data. e.g. "device_logcat". Note dataName may not be unique per invocation. ie implementers must be able to handle multiple calls with same dataName

dataType LogDataType: the LogDataType of the data

dataStream InputStreamSource: the InputStreamSource of the data. Implementers should call createInputStream to start reading the data, and ensure to close the resulting InputStream when complete.

logFile LogFile: the LogFile containing the meta data of the saved file.

testRunEnded

public void testRunEnded (long elapsedTime, 
                HashMap<String, MetricMeasurement.Metric> runMetrics)

Reports end of test run. FIXME: We cannot have two Map<> interfaces with different type, so we have to use HashMap here.

Parameters
elapsedTime long: device reported elapsed time, in milliseconds

runMetrics HashMap: key-value pairs reported at the end of a test run with MetricMeasurement.Metric.

testRunFailed

public void testRunFailed (String failureMessage)

Reports test run failed to complete due to a fatal error.

Parameters
failureMessage String: String describing reason for run failure.
