Direct Known Subclasses:

TestName

public class TestWatchman
extends Object
implements MethodRule

TestWatchman is a base class for Rules that take note of the testing action, without modifying it. For example, this class will keep a log of each passing and failing test:

 public static class WatchmanTest {
        private static String watchedLog;
 
        @Rule
        public MethodRule watchman= new TestWatchman() {
                @Override
                public void failed(Throwable e, FrameworkMethod method) {
                        watchedLog+= method.getName() + " " + e.getClass().getSimpleName()
                                        + "\n";
                }
 
                @Override
                public void succeeded(FrameworkMethod method) {
                        watchedLog+= method.getName() + " " + "success!\n";
                }
        };
 
        @Test
        public void fails() {
                fail();
        }
 
        @Test
        public void succeeds() {
        }
 }
