A test-only type your app uses to test app migration extensions.
Use this type in unit tests that your containing app hosts.
Calling the tester from your unit tests allows you to communicate with your app migration extension to valdiate your migration code.
In your tests, create an instance of `AppMigrationTester`, then access its ``exportController`` and ``importController`` properties to exercise export and import functionality, respectively.
> Warning: Use `AppMigrationTester` only in unit tests, not in production code. The tester doesn't operate in a production environment.

unownedExecutor
TypeScript
get unownedExecutor(): SDKHandle
Swift declaration
nonisolated final var unownedExecutor: UnownedSerialExecutor { get }
Retrieve the executor for this actor as an optimized, unowned
reference.
This property must always evaluate to the same executor for a
given actor instance, and holding on to the actor must keep the
executor alive.
This property will be implicitly accessed when work needs to be
scheduled onto this actor. These accesses may be merged,
eliminated, and rearranged with other work, and they may even
be introduced when not strictly required. Visible side effects
are therefore strongly discouraged within this property.
