Question

我想验证是否与may db模拟对象存在x次交互。这样做是否与'verifyZeroInteractions（）'方法相似？

Answer 1

Mockito.verify(MOCKED_OBJ, Mockito.times(number)).YOUR_METHOD_CALL();

Mockito.verify(MOCKED_OBJ, Mockito.atLeast(number)).YOUR_METHOD_CALL();

Answer 2

根据模拟文档，您可以使用verify(mockedList, never()).add("never happened");。

有很多有用的组合来检查您的预期行为。来自Mockito doc的其他示例：

//using mock
mockedList.add("once");

mockedList.add("twice");
mockedList.add("twice");

mockedList.add("three times");
mockedList.add("three times");
mockedList.add("three times");

//following two verifications work exactly the same - times(1) is used by default
verify(mockedList).add("once");
verify(mockedList, times(1)).add("once");

//exact number of invocations verification
verify(mockedList, times(2)).add("twice");
verify(mockedList, times(3)).add("three times");

//verification using never(). never() is an alias to times(0)
verify(mockedList, never()).add("never happened");

//verification using atLeast()/atMost()
verify(mockedList, atLeastOnce()).add("three times");
verify(mockedList, atLeast(2)).add("three times");
verify(mockedList, atMost(5)).add("three times");

或者您可以使用verifyNoMoreInteractions来确保没有其他与您的模拟互动。

//using mocks
mockedList.add("one");
mockedList.add("two");

verify(mockedList).add("one");

//following verification will fail
verifyNoMoreInteractions(mockedList);

此外，您可以使用inOrder来以完全相同的顺序验证多个模拟的交互，并添加verifyNoMoreInteractions（）以确保没有其他与模拟定义的交互。

InOrder inOrder = inOrder(firstMock, secondMock);
inOrder.verify(firstMock).add("was called first");
inOrder.verify(secondMock).add("was called second");
inOrder.verifyNoMoreInteractions();

Answer 3

您可以使用Mockito.verify()方法，将Mockito.times(...)或Mockito.atLeast(..)用作参数。

Answer 4

或更优雅

verify(MOCK, never()).method()

是否有等效的verifyZeroInteractions（）来验证与模拟对象的确切交互次数？
