Static mocked logger tests fail about mockito

[GiorgioRicca]

The reason your test doesn't work as you've written it is because you are trying to verify interactions on the Logger mock instead of the LogService mock. When you write:

verify(logger, times(1)).warn("Test message {}", 15);
You are trying to verify interactions directly on the logger mock, but in your test, you are calling the warn method on a mock of LogService. In other words, you are verifying interactions on the wrong mock.

To make the test work, you should change your verification to reflect the interactions on the correct mock. In this case, you should verify that the warn method of the LogService mock has been called, not the logger's method.

Change the code as following:

        final LogService logService = mock(LogService.class);
        logService.warn("Test message {}", 15);

        verify(logger, times(1)).warn("Test message {}", 15);`

With this modification, you are verifying that the warn method of the LogService mock has been called correctly with the specified parameters.

However, the explanation for why your test doesn't work in the suite is provided in this issue:
