## Class TestWatchman

- java.lang.Object
- - org.junit.rules.TestWatchman

- All Implemented Interfaces:
    MethodRule

  Deprecated.
  Use `TestWatcher` (which implements `TestRule`) instead.

      @Deprecated
      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() {
           }
       }
