Starting March 27, 2025, we recommend using android-latest-release instead of aosp-main to build and contribute to AOSP. For more information, see Changes to AOSP.

IMultiTargetPreparer

public interface IMultiTargetPreparer
implements IDisableable

com.android.tradefed.targetprep.multi.IMultiTargetPreparer

Known indirect subclasses

BaseMultiTargetPreparer, HelloWorldMultiTargetPreparer, StubMultiTargetPreparer

BaseMultiTargetPreparer	Base implementation of `IMultiTargetPreparer` that allows to disable the object.
HelloWorldMultiTargetPreparer	An example implementation of a `IMultiTargetPreparer`.
StubMultiTargetPreparer	Placeholder empty implementation of a `IMultiTargetPreparer`.

Prepares the test environment for several devices together. Only use for a setup that requires multiple devices, otherwise use the regular ITargetPreparer on each device.

Note that multiple IMultiTargetPreparers can be specified in a configuration. It is recommended that each IMultiTargetPreparer clearly document its expected environment pre-setup and post-setUp.

Public methods

setUp

public void setUp (IInvocationContext context)

This method is deprecated.
Use setUp(com.android.tradefed.invoker.TestInformation) instead.

Perform the targets setup for testing.

Parameters
`context`	`IInvocationContext`: the `IInvocationContext` describing the invocation, devices, builds.

Throws
`TargetSetupError`	if fatal error occurred setting up environment
`BuildError`	In case of build related error
`DeviceNotAvailableException`	if device became unresponsive

setUp

public void setUp (TestInformation testInformation)

Perform the targets setup for testing.

Parameters
`testInformation`	`TestInformation`: the `TestInformation` describing the invocation, devices, builds.

Throws
`TargetSetupError`	if fatal error occurred setting up environment
`BuildError`	In case of build related error
`DeviceNotAvailableException`	if device became unresponsive

tearDown

public void tearDown (TestInformation testInformation, 
                Throwable e)

Perform the targets cleanup/teardown after testing.

Parameters
`testInformation`	`TestInformation`: the `TestInformation` describing the invocation, devices, builds.
`e`	`Throwable`: if the invocation ended with an exception, this will be the exception that was caught at the Invocation level. Otherwise, will be `null`.

Throws

tearDown

public void tearDown (IInvocationContext context, 
                Throwable e)

This method is deprecated.
Use tearDown(com.android.tradefed.invoker.TestInformation, Throwable) instead.

Perform the targets cleanup/teardown after testing.

Parameters
`context`	`IInvocationContext`: the `IInvocationContext` describing the invocation, devices, builds.
`e`	`Throwable`: if the invocation ended with an exception, this will be the exception that was caught at the Invocation level. Otherwise, will be `null`.
