ERROR - org.mockito.exceptions.misusing.UnfinishedStubbingException: Unfinished stubbing detected here

Error


org.mockito.exceptions.misusing.UnfinishedStubbingException:
Unfinished stubbing detected here:
-> at 

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();
Hints:
 1. missing thenReturn()
 2. you are trying to stub a final method, you naughty developer!
 3: you are stubbing the behaviour of another mock inside before 'thenReturn' instruction if completed 

Sample Code

Mockito.when(sampleReference.getElement());

Mockito.doReturn(element).when(sampleReference.getElement());

Possible Causes

 1. missing thenReturn()
 2. you are trying to stub a final method, you naughty developer!
 3: you are stubbing the behaviour of another mock inside before 'thenReturn' instruction if completed 

Possible Resolution

Specify then Return 

Mockito.when(sampleReference.getElement()).thenReturn(element);

Mockito.doReturn(element).when(sampleReference).getElement();
