  • Method Details

    • registerExtension

      void registerExtension(Extension extension, Object source)
      Register the supplied Extension, without checking if an extension of that type has already been registered.

      Semantics for Source

      If an extension is registered declaratively via @ExtendWith, the source and the extension should be the same object. However, if an extension is registered programmatically via @RegisterExtension, the source object should be the Field that is annotated with @RegisterExtension. Similarly, if an extension is registered programmatically as a lambda expression or method reference, the source object should be the underlying Method that implements the extension API.

      Parameters:
      extension - the extension to register; never null
      source - the source of the extension; never null
