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

Question

我想验证与可能db模拟对象确实有x次交互。是否有类似于"verifyZeroInteractions(("方法的方法？

Answer 1

您可以使用

验证无交互((

与verifyZeroInteractions((完全相同的行为

Answer 2

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

Answer 3

根据 mockito 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文档的其他示例：

//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");

或者您可以使用验证NoMoreInteraction来确保没有与您模拟的其他交互。

//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 以完全相同的顺序验证多个模拟的交互，并添加 verifyNoMoreInteractions(( 以确保没有与您的模拟定义的其他交互。

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

Answer 4

您可以使用

Mockito.verify()方法传递Mockito.times(...)或Mockito.atLeast(..)作为参数。

Answer 5

甚至更优雅

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