Dies ist eine funktionale Schnittstelle, die somit als Zuweisungsziel für einen Lambdaausdruck oder eine Methodenreferenz verwendet werden kann.

@API(status=EXPERIMENTAL,
     since="1.6.0")
@FunctionalInterface
public interface ProvidePropertyInstanceHook
extends LifecycleHook

Implement this hook to override behaviour that provides the test instance for each property try. Per default the only accessible constructor of the container class is invoked, with all parameters being resolved through applicable ResolveParameterHook hooks.

This hook can only be used in simple cases, since parameter resolution is currently unavailable to implementors.

Caveat: Only one hook per property method is possible.
