java - How to verify that a specific method was not called using Mockito?

Saturday 17 August 2019

First of all: you should always import mockito static, this way the code will be much more readable (and intuitive):

import static org.mockito.Mockito.*;

There are actually many ways to achieve this, however it's (arguably) cleaner to use the

verify(yourMock, times(0)).someMethod();

method all over your tests, when on other Tests you use it to assert a certain amount of executions like this:

verify(yourMock, times(5)).someMethod();

Alternatives are:

verify(yourMock, never()).someMethod();

Alternatively - when you really want to make sure a certain mocked Object is actually NOT called at all - you can use:

verifyZeroInteracions(yourMock)
