As the javadoc indicates, close() is a final method. And Mockito can't mock final methods.
How to mock concrete class void method
Pregunta
I'm trying to mock Lucenes IndexReader.close()
to do nothing.
I thought this should work...
IndexReader reader = Mockito.mock(IndexReader.class);
Mockito.stubVoid(reader).toReturn().on().close(); // old approach
Mockito.doNothing().when(reader).close(); // new approach
but both result in the unit test calling the actual, real close method and ultimately causing a null pointer exception.
What have I missed?
