Public methods

doCleanUp

public void doCleanUp (IInvocationContext context, 
                IConfiguration config, 
                Throwable exception)

Execute the target_preparer and multi_target_preparer cleanUp step. Does the devices clean up.

Parameters
`context`	`IInvocationContext`: the `IInvocationContext` of the invocation.
`config`	`IConfiguration`: the `IConfiguration` of this test run.
`exception`	`Throwable`: the original exception thrown by the test running.

doSetup

public void doSetup (TestInformation testInfo, 
                IConfiguration config, 
                ITestLogger listener)

Execute the target_preparer and multi_target_preparer setUp step. Does all the devices setup required for the test to run.

Parameters
`testInfo`	`TestInformation`: the `TestInformation` of the invocation.
`config`	`IConfiguration`: the `IConfiguration` of this test run.
`listener`	`ITestLogger`: the `ITestLogger` to report setup failures logs.

Throws
`BuildError`
`DeviceNotAvailableException`
`TargetSetupError`

doTeardown

public void doTeardown (TestInformation testInfo, 
                IConfiguration config, 
                ITestLogger logger, 
                Throwable exception)

Execute the target_preparer and multi_target_preparer teardown step. Does the devices tear down associated with the setup.

Parameters
`testInfo`	`TestInformation`: the `TestInformation` of the invocation.
`config`	`IConfiguration`: the `IConfiguration` of this test run.
`logger`	`ITestLogger`: the `ITestLogger` to report logs.
`exception`	`Throwable`: the original exception thrown by the test running.

reportLogs

public void reportLogs (ITestDevice device, 
                ITestLogger logger, 
                TestInvocation.Stage stage)

Report some device logs at different stage of the invocation. For example: logcat.

Parameters
`device`	`ITestDevice`: The device to report logs from.
`logger`	`ITestLogger`: The logger for the logs.
`stage`	`TestInvocation.Stage`: The stage of the invocation we are at.

runDevicePostInvocationTearDown

public void runDevicePostInvocationTearDown (IInvocationContext context, 
                IConfiguration config, 
                Throwable exception)

Invoke the ITestDevice#postInvocationTearDown(Throwable) for each device part of the invocation.

Parameters
`context`	`IInvocationContext`: the `IInvocationContext` of the invocation.
`config`	`IConfiguration`: the `IConfiguration` of this test run.
`exception`	`Throwable`: the original exception thrown by the test running if any.

runDevicePreInvocationSetup

public void runDevicePreInvocationSetup (IInvocationContext context, 
                IConfiguration config, 
                ITestLogger logger)

Invoke the ERROR(ITestDevice#preInvocationSetup(IBuildInfo)/com.android.tradefed.device.ITestDevice#preInvocationSetup(com.android.tradefed.build.IBuildInfo) ITestDevice#preInvocationSetup(IBuildInfo)) for each device part of the invocation.

Parameters
`context`	`IInvocationContext`: the `IInvocationContext` of the invocation.
`config`	`IConfiguration`: the `IConfiguration` of this test run.
`logger`	`ITestLogger`: the `ITestLogger` to report logs.

Throws
`DeviceNotAvailableException`
`TargetSetupError`

runTests

public void runTests (TestInformation info, 
                IConfiguration config, 
                ITestInvocationListener listener)

Runs the test.

Parameters
`info`	`TestInformation`: the `TestInformation` to run tests with.
`config`	`IConfiguration`: the `IConfiguration` to run
`listener`	`ITestInvocationListener`: the `ITestInvocationListener` of test results

shardConfig

public boolean shardConfig (IConfiguration config, 
                TestInformation testInfo, 
                IRescheduler rescheduler, 
                ITestLogger logger)

Attempt to shard the configuration into sub-configurations, to be re-scheduled to run on multiple resources in parallel.

If a shard count is greater than 1, it will simply create configs for each shard by setting shard indices and reschedule them. If a shard count is not set,it would fallback to IShardHelper#shardConfig.

Parameters
`config`	`IConfiguration`: the current `IConfiguration`.
`testInfo`	`TestInformation`: the `TestInformation` holding the info of the tests.
`rescheduler`	`IRescheduler`: the `IRescheduler`.
`logger`	`ITestLogger`: `ITestLogger` used to log file during sharding.

Returns
`boolean`	true if test was sharded. Otherwise return `false`
