Mockito验证不再与任何模拟交互

在Mockito中,有没有办法验证我创建的任何模拟器上没有更多的交互?

例如:

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

有这样的方法吗?

由于verifyNoMoreInteractions采用了一个对象数组,我们必须找到一种方法来获取所有创建的模拟。

您可以创建此课程

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();
    }
}

然后在测试中使用它:

    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
    }
}

或带注释:

@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
    }
}

它有效,但它增加了对mockito内部的依赖。
