Interface TestInstancePostProcessor

All Superinterfaces:
Extension
Functional Interface:
This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface @API(status=STABLE, since="5.0") public interface TestInstancePostProcessor extends Extension
TestInstancePostProcessor defines the API for Extensions that wish to post-process test instances.

Common use cases include injecting dependencies into the test instance, invoking custom initialization methods on the test instance, etc.

Extensions that implement TestInstancePostProcessor must be registered at the class level.

      void postProcessTestInstance(Object testInstance, ExtensionContext context) throws Exception
      Callback for post-processing the supplied test instance.

      Note: the ExtensionContext supplied to a TestInstancePostProcessor will always return an empty Optional value from getTestInstance(). A TestInstancePostProcessor should therefore only attempt to process the supplied testInstance.

      Parameters:
      testInstance - the instance to post-process; never null
      context - the current extension context; never null
      Throws:
      Exception
