Before moving further, it is important to learn that we need to follow different approaches to run the tests on the basis underlying JUnit version is 4 or 5. it has to How to verify that a specific method was not called using Mockito? <. A first attempt may look like: However, this only works if the method logThrowable in the example usage accepts Throwables, and does not require something more specific like a RuntimeException.
