All Implemented Interfaces:

TestRule

Direct Known Subclasses:

ErrorCollector

public abstract class Verifier
   

    extends 
    Object
   
   

    implements 
    TestRule
   

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 Verifier verifier = new Verifier() {
           @Override public void verify() {
              assertTrue(errorLog.isEmpty());
           }
        }

        @Test public void testThatMightWriteErrorLog() {
           // ...
        }
     }
