Can you make mockito (1.10.17) work with default methods in interfaces?
With mockito 2.x, JDK 8 default methods are supported.
With mockito 1.x it's not possible,
Old answer
Unfortunately it's not yet possible (mockito 1.10.19), from the README.md
on the github'page
JDK8 status
Mockito should work fine with JDK8 if you stay away from default methods (aka defender methods). Lambda usage may work just as good for Answers. We're unsure about every JDK8 features at the moment, like serializing a mock that uses a lambda. Error report and pull request are welcome though (contributing guide).
EDIT 1: defender methods and default methods are different names for the same thing.
I hope for a mockmaker replacement that will handle java 8 opcodes properly for such cases as some opcodes have a different semantic in Java 8.
EDIT 2: Updated the mockito readme, and this quote accordingly
I just tried Mockito 2.0.38-beta, and it already works in that version. But Mockito must be told explicitly to call the default implementation.
Foo foo = mock(Foo.class);
assertThat(foo.bar()).isEqualTo(0);
when(foo.bar()).thenCallRealMethod();
assertThat(foo.bar()).isEqualTo(42);
