Class ExternalResourceSupport

  • All Implemented Interfaces:
    AfterEachCallback, BeforeEachCallback, Extension


    @API(status=EXPERIMENTAL,
         since="5.0")
    public class ExternalResourceSupport
    extends java.lang.Object
    implements BeforeEachCallback, AfterEachCallback
    This Extension provides native support for subclasses of the ExternalResource rule from JUnit 4.

    @Rule-annotated fields as well as methods are supported.

    By using this class-level extension on a test class such ExternalResource implementations in legacy code bases can be left unchanged including the JUnit 4 rule import statements.

    However, if you intend to develop a new extension for JUnit 5 please use the new extension model of JUnit Jupiter instead of the rule-based model of JUnit 4.

    Since:
    5.0
