Mockito verify no more interactions with any mock

Question

In Mockito, is there a way to verify that there are no more interactions on any mock I have created?

For example:

public void test() {   ...   TestObject obj = mock(TestObject);   myClass.test();   verifyNoMoreInteractionsWithMocks();  <------- } 

Is there such a method?

Answer 1

Since verifyNoMoreInteractions take an array of object we have to find a way to get all the created mocks.

You can create this class

public class MocksCollector {     private final List<Object> createdMocks;      public MocksCollector() {         createdMocks = new LinkedList<Object>();         final MockingProgress progress = new ThreadSafeMockingProgress();         progress.setListener(new CollectCreatedMocks(createdMocks));     }      public Object[] getMocks() {         return createdMocks.toArray();     } } 

and then use it in your test :

    public class ATest {     private final MocksCollector mocksCollector = new MocksCollector();      @Test     public void test() throws Exception {         A a1 = mock(A.class);         A a2 = mock(A.class);         A a3 = mock(A.class);         assertEquals("wrong amount of mocks", 3, mocksCollector.getMocks().length);         verifyNoMoreInteractions(mocksCollector.getMocks());         a3.doSomething();         verifyNoMoreInteractions(mocksCollector.getMocks()); // fail     } } 

or with annotations :

@RunWith(MockitoJUnitRunner.class) public class A2Test {     private final MocksCollector mocksCollector = new MocksCollector();      @Mock     private A a1;     @Mock     private A a2;     @Mock     private A a3;      @Test     public void test() throws Exception {         assertEquals("wrong amount of mocks", 3, mocksCollector.getMocks().length);         verifyNoMoreInteractions(mocksCollector.getMocks());         a2.doSomething();         verifyNoMoreInteractions(mocksCollector.getMocks()); // fail     } } 

It works but it adds a dependency on mockito internal.
