public class Verifier
extends Object
implements MethodRule

Verifier is a base class for Rules like ErrorCollector, which can turn otherwise passing test methods into failing tests if a verification check is failed

     public static class ErrorLogVerifier() {
        private ErrorLog errorLog = new ErrorLog();
     
        @Rule
        public MethodRule verifier = new Verifier() {
           @Override public void verify() {
              assertTrue(errorLog.isEmpty());
           }
        }
        
        @Test public void testThatMightWriteErrorLog() {
           // ...
        }
     }
