Mockito. Mock single method which throws an exception

Question

I have a class with method impersonate which throws UnsupportedOperationException. So I want to mock only this only method. I know that I can do it with Mockito.spy.

Session session = Mockito.spy(new Session("admin", "adminSpace")); Session imperSession = new Session("test", "testSpace"); when(session.impersonate(any(Credentials.class))).thenReturn(imperSession);

But the problem is that Mockito really calls impersonate and UnsupportedOperationException throws the execution. So what can I do here?

If you have to make sure mockito is not calling your method befor it's mocked you have to use the Mockito.doXXX() methods instead of Mockito.when().

In your case the code should look like:

doReturn(imperSession).when(session).impersonate(any(Credentials.class));
