Estoy tratando de burlarme de un método para ver si manejo una excepción correctamente. Esto es lo más lejos que puedo llegar.

interfaz:

interface SampleManager {
    void deleteVariome(String specimenId, String analysisId) throws Exception;
    // ...
}

prueba de unidad:

// ...
SampleManger sampleManager = mock(SampleManager.class);

// below is line 753
doThrow(Exception.class).when(sampleManager).deleteVariome(sample1.getId(), analysisId);

resultado:

org.mockito.exceptions.misusing.UnfinishedStubbingException: 
Unfinished stubbing detected here:
-> at ...server.ArchiveManagerImplUTest.deleteVariomeFails(ArchiveManagerImplUTest.java:753)

E.g. thenReturn() may be missing.
Examples of correct stubbing:
    when(mock.isOk()).thenReturn(true);
    when(mock.isOk()).thenThrow(exception);
    doThrow(exception).when(mock).someVoidMethod(); <-- this looks a log like what I did!

Hints:

 1. missing thenReturn()

 2. you are trying to stub a final method, you naughty developer! <-- I have a lot of other mocks of this interface in this test that work.
